螺杆钻具拆卸工艺研究

Research on disassembly process of screw drill tool

针对定向井、水平井及多分支井数量增加,螺杆钻具需求量不断增加的问题,为了保证螺杆钻具出厂合格率和减少螺杆钻具现场事故率,本文对螺杆钻具结构及工作原理进行介绍,同时,对螺杆钻具拆卸过程进行详细阐述。

The number of needle directional well,horizontal well and multi branch well is increasing,and the demand of screw drilling tools is increasing.In order to ensure the qualified rate of screw drilling tools and reduce the accident rate in the field of screw drill,this paper introduces the structure and working principle of screw drill tools.At the same time,it describes the process of screw drill disassembly in detail.
