详细探讨了压差卡钻的形成机理,对影响压差卡钻的主次因素进行了分析,认为接触面积、泥饼物性、摩擦阻力是表征压差卡钻的重要参数;钻具结构、钻井工艺、钻井液性能等都会对压差卡钻产生重要的影响。提出了预防压差卡钻的几项综合措施以及发生压差卡钻后进行有效快速解卡的主要方法,并给出浸泡解卡法的有关计算公式。 The forming mechanism of differential pressure stuck drill was discussed in detail. The primary and secondary factors affecting differential stuck drill were analyzed. The contact area, physical properties of mud cake and frictional resistance are the important parameters to characterize the differential pressure stuck drill. Process, drilling fluid properties, etc. will have a significant impact on the pressure stuck. Several comprehensive measures to prevent sticking of differential pressure are proposed, and the main methods for quick and easy carding after differential pressure sticking are given. The relevant formulas of immersion solution are given.
