Claims (1)

Способ промывки песчаной пробки и предотвращения пескования в обводняющейся скважине, включающий монтаж колтюбинговой установки, установку противовыбросового и насосного оборудования, приготовление промывочной пенообразующей жидкости и промывку скважины в зоне образования песчаной пробки, отличающийся тем, что промывку песчаной пробки проводят только до нижних отверстий интервала перфорации, после этого в интервал перфорации закачивают водоизолирующую композицию, например состав на основе поливинилового спирта, образующую водоизоляционный экран, оттесняющий воду от забоя вглубь пласта по радиусу, затем закачивают герметизирующий состав, например полиакриломидную смолу, закрепляющий породу, и после затвердения герметизирующего состава обрабатывают прискважинную зону пласта, например пенокислотным составом, и осваивают скважину.A method of washing a sand plug and preventing sanding in a waterlogged well, including installing a coiled tubing installation, installing blowout preventer and pumping equipment, preparing a washing foam-forming fluid and flushing a well in the sand plug formation zone, characterized in that the washing of the sand plug is carried out only to the lower holes of the perforation interval, after that, a water-insulating composition, for example, a composition based on polyvinyl alcohol, is formed into the perforation interval, forming water olyatsionny screen, pushes water into the formation from the bottom of the radius, then pumped sealant, e.g. poliakrilomidnuyu resin fixating breed, and after curing of the sealing composition is treated with the near-well formation zone, such as foam-acid composition, and the master hole.
