摘　　要：挤水泥封堵是油田开发中常见的工艺措施,针对目前挤水泥封堵过程中出现的井涌、井漏、管外(或层间)窜、油层污染等问题,研发出一种新型的可取式插管桥塞。该桥塞具有可取、坐封准确、防卡、防粘等特点,并形成了多种井下封堵管柱,能够解决挤水泥封堵过程中出现的上述问题,并且降低了挤水泥封堵风险,缩短了施工周期。目前为止在江苏油田现场应用效果明显,成功率达100%。In the use of the general bridge plug,some difficulties, such as well kick, lost circulation and channeling in the process of ash squeezing and plugging are existed.The paper puts forward to solve the problem by developing a new removable bridge plug. The pulg has characteristics of removable, setting precision, preventing block and preventing adhesion,and can build multiform plugging pipe, which can solve the problem above and reduce the venture of ash squeezing and plugging,thus saving the work time.
