螺杆钻旁通阀是螺杆钻具中的一个主要的零件,主要是用于钻柱内的通道与井筒环形空间之间的沟通,用来保障钻柱内泥浆在下钻的过程中能够方便流到背环形空间,以免污染井台。对于它的原理与基本的机构以及常见的故障都是需要进一步的探究,找出修改方案,进一步的提高螺杆钻具工作的稳定性和可靠性。此次论文主要就是关于螺杆钻具旁通阀故障的分析与结构的优化。
Screw drill bypass valve is a major part of the screw drill, mainly used for communication between the drill string channel and the annulus of the wellbore, to protect the drill string mud in the drilling process to facilitate the flow of Back annular space, so as not to pollute the manhole. For its principles and basic institutions and common faults are the need for further exploration to identify changes to the program to further enhance the stability and reliability of screwdriver work. This paper is mainly about screw drill bypass valve failure analysis and structural optimization.
