Annotation:
The existing carbonate reservoir development system is currently less effective than the development of terrigenous reservoirs and the ongoing measures to organize and strengthen the reservoir pressure maintenance system are of small success. To improve the injection wells efficiency there required a research to identify filtration channels, to determine the direction of the injected fluid movement and to estimate the filtration rate of the working agent. The analysis of the hydrodynamic system of carbonate reservoirs of the Verei-Bashkir deposits of the Dachnoye field in the Republic of Tatarstan based on the results of tracer studies made it possible to establish a hydrodynamic connection between injection and production wells.
Based on the data obtained, the filtration rate of the injected fluid was calculated, the velocity fields were built, and the fractured type of reservoirs was confirmed.
