摘　　要：黄沙坨油田属于火山岩裂缝性气顶边底水油藏，开发后期由于地层压力下降，油层脱气，油井结蜡程度加重．油井热洗时易造成地层伤害，井下安装多功能阀后热洗，在一定程度上解决了生产的难题。Huangshatuo fractured volcanic gas field belongs to the top edge and bottom water reservoir, develop later due to formation pressure decreases, reservoir degassing, increased level of oil wax, hot oil wells could easily lead to formation damage during washing, after the underground installation of multi-function valve hot wash, to a certain extent, solve the production problems.

关 键 词：井下多功能阀 热洗 排液期 溶解气驱
