尾管固井实际作业中经常会遇到各种失效问题,如尾管悬挂器提前坐挂、丢手失效、坐挂失败等,对施工效果影响比较大。结合实际经验确定,问题发生主要原因是胶塞失效,施工时钻杆胶塞、尾管胶塞和碰压座协调性差。为提高施工效率,需要就尾管固井胶塞失效问题进行分析,有针对性采取措施进行优化,本文对此进行了简要分析。 Tail pipe cementing often encountered in the actual operation of a variety of failure problems, such as the tail pipe hanger sits in advance, losing hands, hanging failure, the construction of a greater impact. Combined with the actual experience to determine the main reason for the problem is the rubber stopper failure, the construction of the drill pipe rubber stopper, tail pipe rubber stopper and abutment poor coordination. In order to improve the construction efficiency, it is necessary to analyze the failure of the cementing plug in the tail pipe and to take some measures to optimize it. In this paper, a brief analysis is given.
