“…The object of research is the change in the structure of a sample of an oil source rock, in this case, the black mudstone of the Bazhenov suite (Russia, Western Siberia) as a result of radical reactions in dispersed organic matter (kerogen) [4][5][6][7][8][9]. As a consequence of microwave treatment, oil and gas generation processes occur, with a natural increase in the volume of hydrocarbons during the transition from a solid state (kerogen) to a liquid (oil) and gaseous (gas).…”

The oil and gas industry is developing rapidly. Based on this, it is necessary to determine new methods of productive prospecting of mineral deposits. One of the most high-tech and perspective methods is computer X-ray microtomography. For this stage, this method is widely used for the different fields of geology and geophysics. The main advantage is the ability to study the sample without destruction, which is especially important in the process of working with the kern material. In this paper, the method of computerized X-ray microtomography is highlighted. A comparative analysis of the voids structure of an oil source rock before and after exposure to microwave fields using the standard DataViewer software is clarified. As a result of this analysis, an increase in the diameter of a sample of a cylindrical shape after treatment with microwave fields was established, and the formation of microcracks was also established. Based on the results obtained, assumptions were made about the formation of hydrocarbon deposits. In other words, the paper discusses in detail the method that allows fixing changes in the structure of the void space of rocks as a result of oil and gas generation flowing under the influence of wave fields.

Estimation of the Impact of Basement Heterogeneity on Thermal History Reconstruction: The Western Siberian Basin

Some of the simplifying assumptions frequently used in basin modelling may adversely impact the quality of the constructed models. One such common assumption consists of using a laterally homogeneous crustal basement, despite the fact that lateral variations in its properties may significantly affect the thermal evolution of the model. We propose a new method for the express evaluation of the impact of the basement’s heterogeneity on thermal history reconstruction and on the assessment of maturity of the source rock. The proposed method is based on reduced-rank inversion, aimed at a simultaneous reconstruction of the petrophysical properties of the heterogeneous basement and of its geometry. The method uses structural information taken from geological maps of the basement and gravity anomaly data. We applied our method to a data collection from Western Siberia and carried out a two-dimensional reconstruction of the evolution of the basin and of the lithosphere. We performed a sensitivity analysis of the reconstructed basin model to assess the effect of uncertainties in the basement’s density and its thermal conductivity for the model’s predictions. The proposed method can be used as an express evaluation tool to assess the necessity and relevance of laterally heterogeneous parametrisations prior to a costly three-dimensional full-rank basin modelling. The method is generally applicable to extensional basins except for salt tectonic provinces.

Основний об'єкт розробки-шельфові пісковики нео кому. В Югрі зосереджено 44 % прогнозних ресурсів Росії категорії Dj, тобто ре сурсів у відкладах і на територіях з доведеною нафтоносністю. Ключовим завданням для Югри є запобігання зниженню видобутку нафти та його стабілізація. Цього можна досягти завдяки активному залученню у розробку важкодобувних запасів нафти. Проаналізовано критерії таких запасів, можливості і результати залучення їх у розробку в умовах родовищ Югри. Це поклади нафти з аномальними фізико-хімічними властивостями, підгазові зони покладів, відклади пласта ЛВ}-2 типу "рябчик", ачимовська товща, тюменська світа, породи доюрського комплексу і баженовська світа. Лише за трьома комплексами (ачимовським, баженовським і тюменським) приріст видобутку нафти в 2017 р. дорівнював майже 4 млн т, що можна порівняти з темпа ми зниження видобутку в цілому на Югрі. Початкові геологічні ресурси баженовського комплексу оцінено в 11 млрд т, видобувні ресурси-в 3,1 млрд т. Першочергове джерело стабілізації видобутку нафти в Югрі-залучення в розробку важкодобувних запасів ачимовського і тюменського комплексів. Можливе зростання видобутку таких запасів доюрського комплексу, його річний видобуток становить 2-3 млн т. Ресурси баженовського комплексу поповнять спадистий видобуток нафти до 2030 р. Ключові слова: нафтовидобуток, важкодобувні запаси, ачимовський, тюменський, доюрський і баженовський комплекси, Югра.
