摘　　要：自转式空气锤是在传统空气锤的基础上,利用高压气体实现钻头旋转的一种新型空气锤。它在工作时并不需要钻柱旋转,因此可以有效克服传统空气锤的局限于打直井的不足。在垂直井段,常规空气锤气体欠平衡钻井中的机械钻速较常规钻井液钻井提高数倍甚至数十倍。用气体螺杆配常规空气锤在气体定向井中应用未获成功,这极大地限制了空气锤的应用,针对这一问题而立项开展了自转式空气锤研制。文章就自转式空气锤的工作原理以及关键零部件螺旋棒和螺旋母的设计进行了分析。In the vertical well section, ROP of the conventional air hammer in gas drilling increased by several times or even several dozen times compared with underbalanced drilling. Gas screw with conventional air hammer has not been successful in direction gas well, which greatly limits the application of air hammer. To solve this problem, the air hammer with self-propelled round was developed. This paper analyzed the working principle of air hammer with Self-propelled Round Bit, and design of Spiral Rod and Spiral Nut which are the key components.
