Abstract
The article discusses the unsteady drainage as one of the ways to increase oil recovery. With this well operation process, optimal periods of pump switching are determined to increase the oil flow rate and reduce the watercut. The object of study is the "reservoir — well — pump" system. The purpose of the study is to ensure efficient operation of wells. We use the descriptive method, including the analysis of transient processes of the "reservoir — well — pump" system on a simulation bench, interpretation of transient graphs, and comparison and generalization of the results. The research results showed the dependence of the pressure change on the pump operation mode, i.e. the dependence of the formation parameter on the change in the flow resistance of the "reservoir — well — pump" system. For each transient process, the optimal period of pump operation was determined equal to 3 τ, which will ensure efficient well production mode.
