| 中文摘要:针对大庆油田深部裂缝性地层漏失严重、桥塞堵漏材料堵漏效果不佳的问题,引入了弹性体型胶黏材料,与桥塞堵漏材料复配,形成了热塑性复合堵漏技术,并在大庆油田25口深井中进行了现场试验和应用。现场数据表明热塑性复合堵漏技术较桥塞堵漏技术堵漏效果更佳,堵漏成功率100%,承压7.5MPa,未发生由于恶性漏失导致提前完钻的情况。 |

| Abstract:In view of the serious leakage of deep fractured formations in Daqing Oilfield and the poor plugging effect of bridge plug plugging materials, the thermoplastic composite plugging technology was formed by introducing elastic adhesive materials and mixing them with bridge plug plugging materials. Field tests were carried out in 25 deep wells in Daqing Oilfield. The field test data show that the thermoplastic composite plugging technology has better plugging effect than the bridge plug plugging technology. The plugging success rate is 100%, the pressure bearing is 7.5MPa, and the drilling is not completed ahead of schedule. |
