Based on the results of the research, a technology has been developed to control the process of watering productive reservoirs and production wells by injecting carbon dioxide near the initial gas-bearing contour, which are characterized by high technological efficiency. According to the results of the studies, an increase in the natural gas recovery factor can be achieved by implementing the technology of carbon dioxide injection according to the duration of the period of its injection into the reservoir, which, with battery placement of injection wells at the initial gas-bearing contour and production wells in the center of the reservoir, is four months per hundred meters of distance between and production wells, and in the case of cyclic injection - with an injection cycle duration of 8 months. To obtain the maximum values of the natural gas recovery factor, it is necessary to provide an appropriate ratio of the distance between injection wells to the distance between production wells. According to the calculation results, the ratio of the distance between injection wells to the distance between production wells is 1.29 for a homogeneous reservoir and 0.97 for a heterogeneous reservoir. An increase in the natural gas recovery factor by injecting carbon dioxide can be achieved by substantiating rational technological parameters for the operation of injection and production wells. To ensure high hydrocarbon recovery rates, it is necessary to ensure a rational ratio of the rate of carbon dioxide injection to the rate of natural gas production at the level of 1.25. The introduction of the developed technologies for increasing the final hydrocarbon of the extraction of natural gas reservoirs in the waterdrive will significantly intensify the process of hydrocarbon production and reach the global level of solving this problem
