摘要
本文就大连交流岛地热井施工过程中,正循环钻至633m时,孔内涌水量大,沉渣严重,导致正循环钻进无法顺利实施,后采用气举反循环技术进行清渣钻进,效果很好。
In the process of geo-thermal drilling at Jiaoliudao in Dalian,normal circulation is used to 633 meters,a lot of water gushes out and cuttings is deposited.This leads to the project cannot be implemented.Then air lift reverse circulation is used to removing cuttings,good results is achieved.This paper introduces the application situation of air-lift reverse circulation and construction experience.
