针对油水井出现水淹层、油气枯竭层、套管外窜通、套管损坏等问题,常利用液体压力挤压堵剂使之进入地层缝隙或油层套管外,或是利用液体输送堵剂在井筒套管内留一定长度的灰塞,从而实现封堵封窜。为提高封堵成功率,降低封堵成本,近年来解剖分析每次封堵施工,不断研究封堵材料,优化封堵技术,完善封堵工艺,形成了适合纯梁油区特点的封堵技术,通过应用,收到了很好效果。
For oil and water wells appear flooded layer, depleted layer, casing outside channeling, casing damage and other issues, often using liquid pressure to squeeze plugging agent into the formation gap or casing, or the use of liquid blocking agent In the wellbore casing to stay a certain length of the gray plug, in order to achieve blocking blocking channeling. In order to improve the success rate of plugging and reduce the cost of plugging, in recent years, each plugging construction has been anatomized and analyzed, and the plugging materials, the plugging technology, the plugging technology, the plugging technology , Through the application, received good results.
