油田开发中 ,为了封堵报废油层、高压水层、套损井段 ,完成试油过程中的上返作业 ,经常采用注入水泥浆在井内形成坚固的水泥塞来实现。目前 ,国内油田大多采用油管输送注水泥工艺 ,该项工艺施工较为复杂 ,施工时间长 ,劳动强度大而且作业成本高。为简化现有注水泥工艺 ,降低作 In the development of oilfields, in order to plug the used oil layer, the high pressure water layer and the casing damage section and finish the returning operation in the test oiling process, the cement slurry injected into the well is often used to form a solid cement plug. At present, most domestic oilfields use the pipeline transportation cementing process. The construction of the process is complicated, the construction time is long, the labor intensity is large, and the operation cost is high. To simplify the existing cementing process, reduce the work
