Dolomitization of high-carbon rocks of Bazhenov horizon is an indicator of the appearance of the oil inflows in the well, i.e., it controls netgeneral caused by conditional heating.

The extent of secondary dolomitization should be the measure of thermal effect on rocks. This is in accordance with theoretical views by G. N. Perosio, and N. T. Mandrikov (1971) showed on the example of Western Siberia clear communication of location proctological (Dolomites) with the zones of tectonic disturbances of the sedimentary cover, where there was an active circulation of high temperature groundwater. In this regard, it is important to emphasize that a dry hole, the number of us analyzed wells is the greatest distance from the faults. In high-carbon Bazhenov horizon thickness rarely experienced hydrothermal-metasomatic dolomitization. In rare cases, clay-siliceous high-carbon, the breed has undergone this change.

Wells with high flow rate, timed to the tectonic dislocations, characterized by a sharp increase in the quantity of dolomite. On the formation of numerous nests and veinlets composed of this mineral, it is not sufficient domestic resources, Mg and Ca that have algae and clay minerals. The source of Mg rolling stock could be iron-magnesian chlorite or the dolomite contained in the composition of Paleozoic shales. Minerals were destroyed during periods of structural adjustment hot aggressive waters, which redistributed transformed into a solution element in the sedimentary cover at the most permeable areas.
