Abstract

The article studies an oil deposit in the carbonate dankov-lebedyansk sediments of the oil field, which are characterized by reduced productivity compared to the lower lying terrigenous Upper and Middle Devonian sediments. The dankov-lebedyansk sediments were sporadically studied during active development of highly productive reservoirs, which explains their low geological study. In the conditions of depletion of the main exploitation object, the relevance of additional study of the deposit in the dankov-lebedyansk horizon is undoubted. The data on the geological study of the deposit, including core materials, open and closed hole logging, sampling, testing and development data are summarized. It is proved that the reservoir is understudied and it is established that structural and lithological factors are determinant in the spatial distribution of oil-bearing capacity in the reservoir. In wells previously drilled for the main production object for final confirmation of oil-bearing capacity of the proposed promising intervals before stripping and sampling are recommended research by neutron generator and carbon oxygen logging. If oil-bearing capacity is confirmed, a set of measures is justified to involve the identified oil-bearing intervals and reservoirs into development with sidetracking and horizontal drilling, hydraulic fracturing, acid treatments, simultaneous separate exploitation and other methods recognized as the most effective in carbonate rocks.
