海洋钻机起升系统设备故障分析及预防措施

The Fault analysis and Prevention measure for offshore rig raise system equipments

在海洋钻井作业中,钻机起升系统不仅承担着起下钻具和下套管的常规作业任务,还担负着处理井下复杂故障,进行打捞、震击、解卡作业等特殊任务,起升系统一旦发生故障,将造成无可挽回的重大损失。因此,本文通过对海洋钻机起升系统进行故障分析,确认其故障产生原因,给出了相应的预防措施,以提高海洋钻机起升系统的可靠性和安全性。

In the operation of offshore oil,offshore rig hoisting system not only take the regular task of descending drilling tool and casing pipe,but also taking on dealing with the complicated downhole failure,taking salvage,jarring,free stick such special tasks.Once the hoisting system has a ny problem,great irresistible loss will happen.This paper will take a analysis on the problems of hoisting system,affirm the reasons for that,putforw ard corresponding precaution measures,and improve the reliability and security of offshore rig hoisting system.
