Abstract
Способ промывки проппантовой пробки в газовой или газоконденсатной скважине после завершения гидравлического разрыва пласта, включающий спуск гибкой трубы и закачивание в скважину промывочной жидкости, отличающийся тем, что спуск гибкой трубы до головы проппантовой пробки проводят со скоростью 0,1 м/с, после этого осуществляют промывку ствола скважины и ступенчатое углубление гибкой трубы на глубину 1-3 м со скоростью 0,001 м/с с постоянной подачей аэрированной промывочной жидкости и с поддержанием 100% выхода циркуляции из скважины на каждой ступени углубления гибкой трубы, при этом циркуляцию на каждой ступени проводят не менее двух циклов.A method of washing a proppant plug in a gas or gas condensate well after completion of a hydraulic fracturing, including releasing a flexible pipe and pumping a washing fluid into the well, characterized in that the flexible pipe is lowered to the head of the proppant plug at a speed of 0.1 m / s, after which flushing the wellbore and stepwise deepening the flexible pipe to a depth of 1-3 m at a speed of 0.001 m / s with a constant supply of aerated flushing fluid and maintaining 100% of the circulation output from the well for each the first step of deepening the flexible pipe, while the circulation at each stage is carried out for at least two cycles.
