FIELD: oil and gas extractive industry. ^ SUBSTANCE: method includes forming a screen of viscous-elastic mass in well via interaction of working liquid pumped into well in form of alkali waste of kaprolaktam production or its solution, with influx liquid. Necessary speed of transformation of viscous-elastic mass and intensiveness of filling of well adjacent area with it is adjusted by mode of pressing of working liquid into influx zone. For this purpose pressure increase is alternated with pressure decrease. Pressure is decreased for 10-50% from achieved maximum pressure. Relation of exposure time for increased pressure to decreased pressure time is taken in limits 1.1-5.0. ^ EFFECT: higher efficiency. ^ 7 cl, 1 ex |
