Abstract:

In Western Siberia, on numerous oil fields and newly drilled ultradeep wells (SG-6 and SG-7) as well as by core, logging materials, cavernous-fractured, fractured cavernous-porous space is established, not only in the upper part of the basement (the weathering crust), but in decompressed rocks located at greater depth, below the basement surface. New seismic technology (using the scattered waves) allows today to map the zones and areas of reservoir rocks distribution in the interior of the basement. Evaluation of hydrocarbon potential from the geochemical position is based on the isolation in the section of oil and gas source strata, which in a first approximation are fixed by the generating capabilities of oil and gas source deposits is determined by the results of the analysis Rock-Eval, reflecting the content and composition of organic matter and the nature of catagenetic transformations. Study of catagenetic staging of organic matter is a necessary tool for geochemical evaluation of hydrocarbon potential, and in the first place, it refers to the deep, heterogeneous, sometimes dislocated Paleozoic deposits of the West Siberian oil and gas basin. Using the new features of the basement heterogeneity mapping and isolation of reservoir rocks distribution zones and areas, as well as the evaluation of hydrocarbon generating potential of sedimentary source strata, that clothe ledges of the basement, specifically choose and depth of project wells.
