风动潜孔冲击器钻进技术在马里共和国钻井工程中的应用

The Use of Air-driven Down Hole Hammer for Accomplishing the Water Well Drilling Program in the Republic of Mali

介绍了马里450眼钻井工程的地层条件、钻孔结构、设备选择、施工工艺、潜孔冲击器钻进技术、钻进参数的确定以及取得的主要技术经济指标和效益.同时,对风动潜孔冲击器钻进技术的应用作了较系统的总结.

A drilling program for investigation of 450 water wells was accomplished by using the air-driven down hole hammer drilling. In this paper the stratigraphical condition of the drilling site and drill hole structure are described. A summary on drilling technology, drilling parameter determination and the main technicaleconomic targets achieved is also given.
