Abstract

The features of the use of non-hydrocarbon gases for the displacement of residual natural gas from depleted gas deposits are characterized. Using the licensed computer program Computer Modeling Group (CMG), for the conditions of a round-shaped gas deposit with a peripheral battery of injection wells and a central battery of
production wells, the effect on the total (final) gas recovery coefficient and the gas recovery coefficient for residual gas, the ratio of the radius of the battery of production and injection wells, technological parameters of the process under study (pressure of the start of nitrogen injection, duration, rate and cyclicity of its injection) and different systems of areal well placement. Using the results of the study, the optimal values ​​of the parameters of the process of nitrogen injection into the depleted gas deposit were established. The results of the performed studies indicate a significant technological efficiency of nitrogen injection into a depleted gas reservoir to intensify the process of its additional development and increase the final gas recovery.
