气举反循环钻井技术在超深地热井钻探中的应用

The Application of the Air-lift Reverse Circulation Technology to Super-deep Geothermal Well Drilling

本文通过地热钻井气举反循环施工实例,说明其钻井深度可以达到4000m以下的深度。

By analyzing the application example of the air-lift reverse circulation construction technique to geothermal well drilling,this paper explains that air-lift reverse circulation construction technique can drill to over 4000m depth through rational use and arrangement of construction equipment.
