    Актуальность исследования обусловлена необходимостью устранения существующих расхождений во взглядах на возраст палеогеновых промышленно-угленосных отложений на юго-западе Приморья и сопредельных территориях. Цель: осуществить U-Pb-датирования цирконов из третичных образований, встречающихся в пределах Хасанской рифтогенной впадины, что позволит в дальнейшем уточнить схему последовательности их формирования на территории юго-западного Приморья. Объекты: осадочные породы хасанской и назимовской свит, а также риолиты краскинского комплекса. Методы. Изучение зональности и внутренней структуры цирконов выполнено электронным микрозондом JXA-8100, оснащенным катодолюминесцентным детектором, U-Pb-изотопные исследования цирконов были проведены LA-ICP-MS-методом. Результаты. Согласно полученным результатам U-Pb-датирования цирконов из третичных образований Хасанской впадины, установлено, что возраст самой молодой популяции цирконов в песчаниках назимовской и хасанской свит составляет 37-38 млн лет, что соответствует позднему эоцену и совпадает с возрастной оценкой формирования этих свит, полученной ранее по результатам изучения микро- и макрофлоры. Установлено, что поступление цирконов самой молодой популяции в песчаники хасанской (=назимовской) свиты связано с размывом верхнеэоценовых кислых пород краскинского комплекса. Соответственно, это позволяет говорить об одновозрастности вышеперечисленных стратонов и наличии в пределах Хасанской депрессии в кайнозое одного, позднеэоценового, этапа углеобразования, а не двух, как считалось ранее. Это значительно упрощает региональную стратиграфическую шкалу применительно к Хасанской впадине и ее аналогам в других впадинах Приморья и соседних регионах юга Дальнего Востока России. The relevance of the research is conditioned by the need to eliminate the existing division of opinions about the age of the commercially coal-bearing Paleogene deposits in the southwestern Primorye and neighboring territories. The main objective is to carry out U-Pb analysis of zircons from the Tertiary rocks within the Khasan rift valley for later use of these data in specifying the order of formation of the rocks. Objects: sedimentary rocks of the Khasan and Nasimova formations, rhyolites of the Kraskinsky complex. Methods: study on zircon internal zoning and structure with the help of cathodoluminescence detector-equipped JXA-8100 electron microprobe, U-Pb dating of zircons by LA-ICP-MS. Results. The age of 37-38 Ma was determined for the zircons from sandstones of the Nasimova and Khasan formations. This age corresponds to the late Eocene and coincides with the age estimation of these sequences formation inferred from the previous studies on micro- and macroflora. Is has been established that the supply of the youngest population of zircons to the sandstones was due to erosion of the upper Eocene acid rocks of the Kraskinsky complex. This allows a suggestion about the uniformity of age for the above-mentioned stratigraphic units and the existence of one rather than two, as previously believed, stages of coalification in the Cenozoic within the Khasan rift valley. The new data thus considerably simplify regional stratigraphic scale as applied to the Khasan depression and its analogues in Primorye and neighboring regions.

    Актуальность работы связана с государственной задачей увеличения прироста запасов углеводородного сырья и плохой геологической изученностью нижнесреднеюрских отложений юго-востока Западной Сибири. Цель исследования заключена в комплексном изучении геологического строения отложений нижнесреднеюрскoго возраста на территории Томской области, а также в определении перспективных нефтегазоносных зон, обусловленных вторичными процессами. В работе использованы традиционные методы литологического и стратиграфического расчленения разрезов скважин по материалам каротажных диаграмм, результаты петрографического анализа шлифов керна на основании «Дел скважин», а также инновационная технология статистической интерпретации материалов геофизических исследований скважин на предмет выявления низкоомных УВ-насыщенных коллекторов и интенсивностей вторичных геохимических процессов. Представлены результаты обобщения геологического строения и стратиграфии нижнесреднеюрских отложений Томской области. Выделены нефтегазовые комплексы (НГК), и на основе эмпирических данных показана перспективность в образовании УВ залежей каждого НГК. По результатам инновационной интерпретации материалов геофизических исследований скважин определены интенсивности вторичных процессов и вероятность образования низкоомных УВ-насыщенных коллекторов. Определены наиболее перспективные площади их проявления в нижнесреднеюрских отложениях. Выводы. Во-первых, наиболее перспективными НГК в нижнесреднеюрских отложениях Томской области являются надояхский и малышевский комплексы, при условии обнаружения флюидоупоров и ловушек. Во-вторых, наиболее перспективные площади (с точки зрения обнаружения низкоомных УВ-насыщенных пластов) находятся на территориях межструктурных зон либо близко расположенных к ним. В-третьих, корреляции по латерали между выборками усредненных (по разрезу) данных интенсивностей каолинизации с низкоомным параметром, карбонатизации и пиритизации с пористостью позволяют выявить режимы формирования либо разрушения залежей УВ. The relevance of the discussed paper is related to a national objective of increasing a gain of stocks of hydrocarbonic raw materials and bad geological study of the Lower-Middle Jurassic deposits of the Southeast of Western Siberia. The main aim of the consists in complex studying of geological structure of the Lower-Middle Jurassic layers on the territory of Tomsk region as well as in defining the perspectives of oil-and-gas zones caused by the secondary processes. The authors have used the traditional methods of lithological and stratigraphy correlation of cuts of wells on the materials of well logging, descriptions of results of petrographic analysis of shlif on the base of «Affairs of wells», and the innovative statistical interpretation method of the GIS date regarding the identification of low-impedance hydrocarbonic saturated collectors and intensity of the secondary geochemical processes. The paper introduces the results of generalization of a geological structure and stratigraphy of the Lower-Middle Jurassic deposits of the Tomsk region. Oil and gas complexes were allocated and on the base of empirical data the prospects in formation of hydrocarbon deposits of each complex were shown. The intensity of the secondary processes and probability formation of low-resistance collector were based on the innovative statistical interpretation method of the GIS date. The authors determined the areas of higher perspective in Low-Middle Jurassic deposits. The results. Nadoyakhsky and malyshevsky complexes are the most perspective oil and gas companies in the Low-Middle Jurassic deposits of the Tomsk region, in case of detection of impermeable layers and traps. The most perspective areas (from the point of view of detection of the low-impedance hydrocarbonic saturated deposits) are within the territories of interstructural zones, or the ones close located to them. Lateral correlations between the samplings of the average data (on a section) of kaolinization intensities with a low-impedance parameter, carbonization and pyritization with porosity allow revealing the formation modes, or destructions of hydrocarbonic deposits.

    Предмет исследования. Рассмотрены современные подходы к решению задачи мультиклассовой классификации намерений. Под намерением пользователя понимаются входящие пользовательские запросы при взаимодействии с голосовыми помощниками и чат-ботами. Алгоритм должен определить, к какому классу относится обращение. Современные технологии, такие как трансферное обучение и трансформеры, значительно улучшают результаты мультиклассовой классификации. Метод. В исследовании использован метод сравнительного анализа моделей. В свою очередь, каждая модель встроена в общий конвейер для подготовки, очистки данных и обучения модели, но с учетом ее конкретных требований. Для сравнения были выбраны современные модели, которые используются в реальных проектах: логистическая регрессия + TF-IDF; логистическая регрессия + FastText; LSTM + FastText; Conv1D + FastText; BERT; XLM. Последовательность моделей соответствует их историческому происхождению, но на практике эти модели используются независимо от времени их появления, а в зависимости от эффективности решаемой проблемы. Основные результаты. Выполнено исследование эффективности моделей мультиклассовой классификации на реальных данных. Представлены результаты сравнения современных практических подходов. В частности, XLM подтверждает превосходство трансформеров над другими подходами. Выдвинуто предположение, по какой причине трансформеры показывают такой отрыв. Описаны преимущества и недостатки современных подходов. Практическая значимость. С практической точки зрения результаты этого исследования могут быть использованы для проектов, которые требуют автоматической классификации намерений, как части сложной системы (голосового помощника, чат-бота или другой системы), а также как самостоятельной системы. Пайплайн, разработанный во время исследования, можно использовать для сравнения и выбора наиболее эффективной модели для конкретных наборов данных как в научных исследованиях, так и в производстве. Subject of Research. The paper considers modern approaches to the multiclass intention classification problem. The user intention is the incoming user requests when interacting with voice assistants and chatbots. The algorithm is meant for determination what class the call belongs to. Modern technologies such as transfer learning and transformers can improve significantly the multiclass classification results. Method. This study uses a comparative model analysis technique. In turn, each model is inlined into a common pipeline for data preparing and clearing, and the model training but with regard to its specific requirements. The following models applied in real projects have been selected for comparison: Logistic Regression + TF-IDF, Logistic Regression + FastText, LSTM + FastText, Conv1D + FastText, BERT, and XLM. The sequence of models corresponds to their historical origin, but in practice these models are used without regard to the time period of their creation but depending on the effectiveness of the problem being solved. Main Results. The effectiveness of the multiclass classification models on real data is studied. Comparison results of modern practical approaches are described. In particular, XLM confirms the superiority of transformers over other approaches. An assumption is made considering the reason why the transformers show such a gap. The advantages and disadvantages of modern approaches are described. Practical Relevance. From a practical point of view, the results of this study can be used for projects that require automatic classification of intentions, as part of a complex system (voice assistant, chatbot or other system), as well as an independent system. The pipeline designed during the study can be applied for comparison and selection of the most effective model for specific data sets, both in scientific research and production.

    Актуальность исследования обусловлена необходимостью устранения существующих расхождений во взглядах на возраст палеогеновых промышленно-угленосных отложений на юго-западе Приморья и сопредельных территориях. Цель: осуществить U-Pb-датирования цирконов из третичных образований, встречающихся в пределах Хасанской рифтогенной впадины, что позволит в дальнейшем уточнить схему последовательности их формирования на территории юго-западного Приморья. Объекты: осадочные породы хасанской и назимовской свит, а также риолиты краскинского комплекса. Методы. Изучение зональности и внутренней структуры цирконов выполнено электронным микрозондом JXA-8100, оснащенным катодолюминесцентным детектором, U-Pb-изотопные исследования цирконов были проведены LA-ICP-MS-методом. Результаты. Согласно полученным результатам U-Pb-датирования цирконов из третичных образований Хасанской впадины, установлено, что возраст самой молодой популяции цирконов в песчаниках назимовской и хасанской свит составляет 37-38 млн лет, что соответствует позднему эоцену и совпадает с возрастной оценкой формирования этих свит, полученной ранее по результатам изучения микро- и макрофлоры. Установлено, что поступление цирконов самой молодой популяции в песчаники хасанской (=назимовской) свиты связано с размывом верхнеэоценовых кислых пород краскинского комплекса. Соответственно, это позволяет говорить об одновозрастности вышеперечисленных стратонов и наличии в пределах Хасанской депрессии в кайнозое одного, позднеэоценового, этапа углеобразования, а не двух, как считалось ранее. Это значительно упрощает региональную стратиграфическую шкалу применительно к Хасанской впадине и ее аналогам в других впадинах Приморья и соседних регионах юга Дальнего Востока России. The relevance of the research is conditioned by the need to eliminate the existing division of opinions about the age of the commercially coal-bearing Paleogene deposits in the southwestern Primorye and neighboring territories. The main objective is to carry out U-Pb analysis of zircons from the Tertiary rocks within the Khasan rift valley for later use of these data in specifying the order of formation of the rocks. Objects: sedimentary rocks of the Khasan and Nasimova formations, rhyolites of the Kraskinsky complex. Methods: study on zircon internal zoning and structure with the help of cathodoluminescence detector-equipped JXA-8100 electron microprobe, U-Pb dating of zircons by LA-ICP-MS. Results. The age of 37-38 Ma was determined for the zircons from sandstones of the Nasimova and Khasan formations. This age corresponds to the late Eocene and coincides with the age estimation of these sequences formation inferred from the previous studies on micro- and macroflora. Is has been established that the supply of the youngest population of zircons to the sandstones was due to erosion of the upper Eocene acid rocks of the Kraskinsky complex. This allows a suggestion about the uniformity of age for the above-mentioned stratigraphic units and the existence of one rather than two, as previously believed, stages of coalification in the Cenozoic within the Khasan rift valley. The new data thus considerably simplify regional stratigraphic scale as applied to the Khasan depression and its analogues in Primorye and neighboring regions.

    Актуальность работы связана с государственной задачей увеличения прироста запасов углеводородного сырья и плохой геологической изученностью нижнесреднеюрских отложений юго-востока Западной Сибири. Цель исследования заключена в комплексном изучении геологического строения отложений нижнесреднеюрскoго возраста на территории Томской области, а также в определении перспективных нефтегазоносных зон, обусловленных вторичными процессами. В работе использованы традиционные методы литологического и стратиграфического расчленения разрезов скважин по материалам каротажных диаграмм, результаты петрографического анализа шлифов керна на основании «Дел скважин», а также инновационная технология статистической интерпретации материалов геофизических исследований скважин на предмет выявления низкоомных УВ-насыщенных коллекторов и интенсивностей вторичных геохимических процессов. Представлены результаты обобщения геологического строения и стратиграфии нижнесреднеюрских отложений Томской области. Выделены нефтегазовые комплексы (НГК), и на основе эмпирических данных показана перспективность в образовании УВ залежей каждого НГК. По результатам инновационной интерпретации материалов геофизических исследований скважин определены интенсивности вторичных процессов и вероятность образования низкоомных УВ-насыщенных коллекторов. Определены наиболее перспективные площади их проявления в нижнесреднеюрских отложениях. Выводы. Во-первых, наиболее перспективными НГК в нижнесреднеюрских отложениях Томской области являются надояхский и малышевский комплексы, при условии обнаружения флюидоупоров и ловушек. Во-вторых, наиболее перспективные площади (с точки зрения обнаружения низкоомных УВ-насыщенных пластов) находятся на территориях межструктурных зон либо близко расположенных к ним. В-третьих, корреляции по латерали между выборками усредненных (по разрезу) данных интенсивностей каолинизации с низкоомным параметром, карбонатизации и пиритизации с пористостью позволяют выявить режимы формирования либо разрушения залежей УВ. The relevance of the discussed paper is related to a national objective of increasing a gain of stocks of hydrocarbonic raw materials and bad geological study of the Lower-Middle Jurassic deposits of the Southeast of Western Siberia. The main aim of the consists in complex studying of geological structure of the Lower-Middle Jurassic layers on the territory of Tomsk region as well as in defining the perspectives of oil-and-gas zones caused by the secondary processes. The authors have used the traditional methods of lithological and stratigraphy correlation of cuts of wells on the materials of well logging, descriptions of results of petrographic analysis of shlif on the base of «Affairs of wells», and the innovative statistical interpretation method of the GIS date regarding the identification of low-impedance hydrocarbonic saturated collectors and intensity of the secondary geochemical processes. The paper introduces the results of generalization of a geological structure and stratigraphy of the Lower-Middle Jurassic deposits of the Tomsk region. Oil and gas complexes were allocated and on the base of empirical data the prospects in formation of hydrocarbon deposits of each complex were shown. The intensity of the secondary processes and probability formation of low-resistance collector were based on the innovative statistical interpretation method of the GIS date. The authors determined the areas of higher perspective in Low-Middle Jurassic deposits. The results. Nadoyakhsky and malyshevsky complexes are the most perspective oil and gas companies in the Low-Middle Jurassic deposits of the Tomsk region, in case of detection of impermeable layers and traps. The most perspective areas (from the point of view of detection of the low-impedance hydrocarbonic saturated deposits) are within the territories of interstructural zones, or the ones close located to them. Lateral correlations between the samplings of the average data (on a section) of kaolinization intensities with a low-impedance parameter, carbonization and pyritization with porosity allow revealing the formation modes, or destructions of hydrocarbonic deposits.

    Предмет исследования. Рассмотрены современные подходы к решению задачи мультиклассовой классификации намерений. Под намерением пользователя понимаются входящие пользовательские запросы при взаимодействии с голосовыми помощниками и чат-ботами. Алгоритм должен определить, к какому классу относится обращение. Современные технологии, такие как трансферное обучение и трансформеры, значительно улучшают результаты мультиклассовой классификации. Метод. В исследовании использован метод сравнительного анализа моделей. В свою очередь, каждая модель встроена в общий конвейер для подготовки, очистки данных и обучения модели, но с учетом ее конкретных требований. Для сравнения были выбраны современные модели, которые используются в реальных проектах: логистическая регрессия + TF-IDF; логистическая регрессия + FastText; LSTM + FastText; Conv1D + FastText; BERT; XLM. Последовательность моделей соответствует их историческому происхождению, но на практике эти модели используются независимо от времени их появления, а в зависимости от эффективности решаемой проблемы. Основные результаты. Выполнено исследование эффективности моделей мультиклассовой классификации на реальных данных. Представлены результаты сравнения современных практических подходов. В частности, XLM подтверждает превосходство трансформеров над другими подходами. Выдвинуто предположение, по какой причине трансформеры показывают такой отрыв. Описаны преимущества и недостатки современных подходов. Практическая значимость. С практической точки зрения результаты этого исследования могут быть использованы для проектов, которые требуют автоматической классификации намерений, как части сложной системы (голосового помощника, чат-бота или другой системы), а также как самостоятельной системы. Пайплайн, разработанный во время исследования, можно использовать для сравнения и выбора наиболее эффективной модели для конкретных наборов данных как в научных исследованиях, так и в производстве. Subject of Research. The paper considers modern approaches to the multiclass intention classification problem. The user intention is the incoming user requests when interacting with voice assistants and chatbots. The algorithm is meant for determination what class the call belongs to. Modern technologies such as transfer learning and transformers can improve significantly the multiclass classification results. Method. This study uses a comparative model analysis technique. In turn, each model is inlined into a common pipeline for data preparing and clearing, and the model training but with regard to its specific requirements. The following models applied in real projects have been selected for comparison: Logistic Regression + TF-IDF, Logistic Regression + FastText, LSTM + FastText, Conv1D + FastText, BERT, and XLM. The sequence of models corresponds to their historical origin, but in practice these models are used without regard to the time period of their creation but depending on the effectiveness of the problem being solved. Main Results. The effectiveness of the multiclass classification models on real data is studied. Comparison results of modern practical approaches are described. In particular, XLM confirms the superiority of transformers over other approaches. An assumption is made considering the reason why the transformers show such a gap. The advantages and disadvantages of modern approaches are described. Practical Relevance. From a practical point of view, the results of this study can be used for projects that require automatic classification of intentions, as part of a complex system (voice assistant, chatbot or other system), as well as an independent system. The pipeline designed during the study can be applied for comparison and selection of the most effective model for specific data sets, both in scientific research and production.
