Express zoning of the parent suite on density of generated oil resources (by the example of Nyurol'ka megadepression)
The relevance of the research is caused by the need to develop the criteria and to improve the technique of assessing hard-to-produced reserves of shale oil (accumulated in situ) of Bazhenov suite in West Siberian oil-and-gas province.

| description | The relevance of the research is caused by the need to develop the criteria and to improve the technique of assessing hard-to-produced reserves of shale oil (accumulated in situ) of Bazhenov suite in West Siberian oil-and-gas province. The main aim of the research is to define the methodology, a set of initial geological and geophysical data and demonstrate the technique of zoning oil source deposits on shale oil resource density. The object of research is the Upper Jurassic Bazhenov sediments of Mesozoic and Cenozoic section penetrated by deep wells in the south-east of Western Siberia. Methodology and technology of the research. Duration and temperature of the main phase of oil generation are accepted as the key factor detailing the characteristics of the parent suite as the one supplying higher/lower located clastic reservoirs or as shale formation (N. B. Vassoevich, 1967); and the main volume of oil generated, accumulated in situ, or emigrated to the collector, are located there where the parent deposits are/were to a greater extent in the main zone of oil formation (A. E. Kontorovich et al., 1967). The zoning technique is based on the method of paleotemperature modeling which allows reconstructing thermal history of the parent deposits, allocating oil generation sources by geothermal criteria and mapping them. The generated oil resources are estimated by an integral index, depending on the time which the parent suite spent in the main zone of oil formation and on its temperatures. Research results. The paper demonstrates the zoning technique of Nurol'ka megadepression and the structures of its framing, based on the method of paleotemperature modeling that fits organically into the methodology of the theory of oil generation main phase and threshold temperatures for the parent deposits occurrence in the main zone of oil formation. The authors have determined the promising regions and areas of the slate (accumulated in situ) Bazhenov oil. The oil seeps and flows in deep wells from the intervals of the parent rocks and clastic reservoirs prove zoning substantiality. |
