摘　　要：随着安塞油田开发时间的延长,井筒状况日益复杂,井下作业工作量随之持续增加,尤其是隔采、隔注及分注的油水井越来越多,在井下作业中封隔器卡钻事故也呈不断递增趋势。这些问题不仅增加了油水井的维护成本,而且延长了作业时间,直接影响到原油生产。通过典型实例,对Y341型封隔器卡钻的原因进行了详细剖析,总结了现场解卡经验,探索出一套有效解除Y341封隔器卡钻事故的处理方法。The extension of the development of Ansai oilfield results in increasingly complicated condition of well-bores and subse- quently, the workload of borehole operation continuously increases. As inter-layer production, inter-layer injection and zonal injection oil-water wells increase, packer sticking tends to rise progressively. These problems have resulted in not only higher maintenance cost but more working hours, directly affecting oil production. Therefore, detailed analysis has been made of the causes of the sticking of Y341 packers via representative examples, and on-site unstuck experience has been summarized to find a series of effective treatment for the sticking of Y341 packers.
