СПОСОБ ЛИКВИДАЦИИ НАПОРНОЙ ВОДОЗАБОРНОЙ СКВАЖИНЫ

摘要

FIELD: well construction technologies. ^ SUBSTANCE: fountain armature is mounted on casing pipe for abolishing of self-pouring. Cementing solution is fed into well. According to invention prior to feeding of cementing solution, compressed air is fed into casing string through grid pipeline for displacement of water from casing string through well filter to upper mark of water-bearing level. Given pressure is supported in casing pipe. Compressed air is fed until hardening of cementing solution. ^ EFFECT: full and reliable liquidation of well. ^ 1 dwg
