油田钻具失效分析及预防措施研究

Study on failure analysis and preventive measures of drilling tools in oilfield

油田地层结构复杂,其压力、岩性和温差变化相对较大,不断增加钻井的难度系数,造成钻具出现不同类型的失效。基于此,本文主要针对油田钻具的失效类型加以分析,并提出相关的预防措施,确保油田钻井工程可以有序开展,切实降低钻具失效概率。

The formation structure of oilfield is complex,and its pressure,lithology and temperature difference vary relatively greatly,which continuously increases the difficulty coefficient of drilling,resulting in different types of drilling tool failures.Based on this,this paper mainly analyzes the failure types of oilfield drilling tools,and puts forward relevant preventive measures to ensure that oilfield drilling engineering can be carried out in an orderly manner,and effectively reduce the failure probability of drilling tools.
