| Summary: | The relevance of studying the unallocated subsoil fund of the east of the Tomsk region is determined by the prospects and underexplored right bank of the Ob River. The subsoil user does not want to take risks there, the same about the State. However, oil companies will be forced to develop the eastern regions when production at the oil fields on the left bank drops to a critical level of profitability. A number of promising areas for exploratory drilling have already been identified on the right bank. The main aim of the research of geologists and geophysicists in the oil industry in Western Siberia and in particular the Tomsk region is a significant increase in reserves and accordingly prevention decline in oil production. This is the aim of the present work. The objects of the study are hard-to-recover reserves which requires the solution of the scientific problem of theoretical and experimental study of thermodynamics and material composition of the Western Siberia Paleozoic. The key geodynamic parameter that determines geotemperatures and the time of its impact on the centers of hydrocarbon generation is the heat flow of the foundation roof. It serves as the basis for basin modeling in prospecting and exploration. The construction and general analysis of the heat flow density map of the foundation roof of the Tomsk region east were carried out for a joint study of the prospects for the oil and gas potential of the poorly studied Bakchar mezodepression and the areas of the preliminary forecast of the East Paidugin megadepression. Methods. The original software «TeploDialog» was used to perform the simulation. This software package implements specially formulated direct and inverse geothermal problems under sedimentation conditions. Determining the value of the heat flow density from the roof of the foundation is complicated by taking into account many processes occurring both in the bowels and on the surface of the Earth. Therefore, an integral approach was used in the calculations, allowing these processes ... |
