PROCESS OF TREATMENT OF INJECTION WELLS

摘要

The process of treatment of injection wells includes sequential pump-in to the critical area of formation of water solutions of surface-active substances, with giving rise to gas inflow with pressing out solutions to ejection. By the first portion of the solution one washes the pump-compressor pipes with the following pressing-out of solution from the well, the second portion of the solution is lowered to the face, with soaking and with following pressing-out of solution from the well, and the third portion of the solution is pumped-in to the bed, with soaking and pressing out by gas from the bed.
