钻井井架可靠度分析

井架作为石油钻井生产的一种特种设备,价格昂贵,安全性要求高,井架可靠性分析和评估显得尤为重要。基于可靠性理论,根据井架模型的实测数据,给出了井架可靠性指标的判断方法。最后给出了井架模型失效概率的计算方法和计算结果。

An Analysis on the Reliability of Drilling Derricks

The drilling derrick,as one special device of petroleum drilling production,is very expensive and is highly required in security,so it seems to be very important to do an analysis and evaluation on the reliability of drilling derricks.Based on the theory of reliability and measured data of derrick models,the methods of judging the reliability index of drilling masts are offered in the paper,coupled with the calculating methods and the calculated result about the failure probability of drilling derrik models.
