Abstract
Background In order to maintain reservoir pressure for injection into the wells, it is preferable to use wastewater that is produced together with the hydrocarbon liquid. After separating it from oil in integrated oil treatment plants, it becomes necessary to clean it before injection into the reservoir. Aims and Objectives Based on the analysis of existing wastewater treatment systems before their injection into wells, develop an improved application scheme that does not require significant material investments for its implementation. Results The application of the sewage treatment system will reduce the occupied areas of the purification system by combining them into one, improve the quality of treatment, obtain additional sources of recycled water for technical use and provide the required volume of water for pulsed non-stationary water flooding.
