In the process of geo-thermal drilling at Jiaoliudao in Dalian,normal circulation is used to 633 me-ters,a lot of water gushes out and cuttings is deposited.This leads to the proj ect cannot be implemented . Then air lift reverse circulation is used to removing cuttings ,good results is achieved.This paper intro-duces the application situation of air-lift reverse circulation and construction experience.
