| titleOfInvention | Method of washing of sand plug and prevention of addition of sand in water producer under conditions of lifting of gas-water contact |
| abstract | FIELD: mining. n SUBSTANCE: method consists in assembling of coiled tubing facility, assembling of blowout preventer and pump equipment, preparing of washing of foaming fluid, washing well in zone from sand plug occurring to bottomhole of well, locating gas-water contact position by means of geophysical methods, and pumping water insulating composition into perforation interval with forming water insulating screen displacing underground water. Further a grouting mortar is poured into well to level 20 m above the flowing gas-water contact; while lower apertures of perforation interval are shut. After grouting mortar has been hardened, a sealing composition is pumped through upper holes of the perforation interval. When sealing composition hardening period has been completed, bottomhole zone of the reservoir is treated with an acid solution and development of well commences. n EFFECT: increased efficiency of plug removal under conditions of low reservoir pressure; eliminating conditions of sand occurring. n 6 dwg |
