摘要
本文介绍了螺杆钻具的基本结构,阐述了螺杆钻具的工作原理,分析了泥浆螺杆钻具在国内外物探钻井的施工应用,探讨了其在物探钻井中的适应地层和技术优势。另外还对空气螺杆钻具在物探钻井中的需求和可行性进行了简单探讨。
The paper introduced the structure and operational principle of downhole motor firstly. Then the paper analyzed its application in domestic and international geophysical prospecting to show its suitable formation and technical ad- vantages. In addition, the requirement and feasibility of downhole motor in geophysical exploration drilling are also discussed.
