摘要
本文针对伊拉克某区块一年多来多次发生钻具纵向失效的失效原因进行了分析。钻具纵向失效的主要原因是由于钻具横向材料强度和冲击韧性低和钻井过程中钻具和井壁摩擦产生的热裂纹造成的。
This paper provides insights of causes of drill longitudinal failure in X block,Iraq,which include low horizontalmaterial strength and impact toughness of drilling tool as well as heat crack formed by friction between drilling tool and wall in theprocess of drilling.
