СПОСОБ ЭКСПРЕСС-РЕМОНТА ПО ВОССТАНОВЛЕНИЮ ГЕРМЕТИЧНОСТИ ГАЗОВОДОНЕФТЕПРОЯВЛЯЮЩИХ СКВАЖИН |
摘要 |
FIELD: oil and gas extractive industry. ^ SUBSTANCE: excessive pressure is dropped from inter-column spaces down to atmospheric value. Inter-column and behind-column spaces up to upper zone of well mouth are filled with pressurizing liquid based on water solution of saponified tall pitch with concentration ranging from 5 to 17% and viscosity (11-41).10-4 Pa.s by means of at least single free topping or forcing it into behind-column and inter-column spaces under pressure 5 - 50 atmospheres. Pressurization of wells is determined in inter-column spaces on basis of drop down to zero value of excessive pressure in them using manometer or flow of fluids from inter-column spaces of well shown by flow meter. ^ EFFECT: simplification of maintenance operations. ^ 3 ex |
