METHOD FOR TREATMENT OF WELLS OF UNDERGROUND GASHOLDERS

机译:处理地下金矿井的方法

摘要

A method for treatment of wells of underground gasholders includes sequential injection into critical area of formation of two types of solutions of surface-active substances and prescribes injection and keeping in formation first portion of high-concentration solution of surface-active substance (SAS) with washing effect, generation of gas inflow with displacement of solution to discharge and injection second portion of solution of non-ionic surface-active substance. To first portion of high-concentration solution of surface-active substance one adds foaming inhibitor. As second portion one uses solution of inhibitor of foaming with concentration 0.3-0.5 wt. % that is pressed with high pressure gas to borehole zone of formation.
