摘要

绝大多数的水平井井下动力钻具是以螺杆钻具为基础构成的。文中介绍了螺杆钻具的基本结构和工作原理,分析了螺杆钻具的理论工作特性和实际工作特性,讨论了有关基本概念,并由此阐述了螺杆钻具在现场应用的操作注意事项。

Abstract

Most downhole power drills for horizontal drilling are constituted basically by positive displacement drills. This paper presents the basic structure and mechanlsm of posltive dlsplacement drills, analyzes the theoretical and practical performance of positive displacement drills and discusses the basic concepts involved as well as its operational precau tions in field application.
