Terms and principle of formation of carbonate productive strata of Salyukinskoye oilfield based on the analysis of the statistical variability of the reservoir

Authors: V.G. Miroshkin (NK Rosneft - NTC LLC, Krasnodar, Russian Federation)

Paleotectonic analysis of materials of Salyukinskoye oilfield in cross-section of Upper Carboniferous-Lower Permian age by the method of statistical model of rocks variability is executed. A representation about the conditions of sedimentation of deposits of the given age is obtained, the geological model for the further development of the field is refined.

The executed paleotectonic analysis of data on the Upper Carboniferous and Lower Permian sediments of the Salyukinskoye oilfield territory has shown that at creating a geological models of reservoirs С3 (С2+С3), P11 и Р12, a major complicating factor is quite widespread in these beds occurrence of bioherms, to which hydrocarbon deposits are confined at the field. The described method for studying the conditions of sedimentation is quite applicable to the fields, formed by organogenic carbonate rocks.

Key words: paleotectonics, statistical model, variability, carbonate rocks.
