探讨了MMH正电胶的防漏、堵漏机理,室内实验研究了MMH正电胶防漏、堵漏体系的基本组成,介绍了MMH正电胶防漏、堵漏体系现场应用的关键技术。MMH正电胶防漏、堵漏技术在塔里木油田20多口井中的应用表明,MMH正电胶防漏、堵漏技术对渗透性和微小裂缝等易漏地层有良好的防漏、堵漏效果,堵漏成功率在85％以上。MMH正电胶防漏、堵漏技术具有现场操作简单,使用方便,成本低廉的特点。
The leakage prevention and plugging mechanism of MMH positive rubber was discussed. The basic composition of MMH positive rubber leak-proof and plugging system was studied in laboratory. The key technologies of MMH positive rubber leak-proof and plugging system were introduced. MMH positive rubber leak-proof, plugging technology in Tarim Oilfield more than 20 wells in the application shows that, MMH positive rubber leak-proof, plugging leakage and permeability of fine cracks and other leaky formations have a good leak-proof, plugging effect , Plugging success rate above 85%. MMH positive plastic leak-proof, plugging technology with on-site operation is simple, easy to use, low cost features.
