| 中文摘要:针对陕北延长油田黄土层漏失具有井底温度低、漏失严重、常规堵漏材料与方法堵漏效果差的特点，研究出了一种低温下快速实现交联的PLC聚合物交联凝胶。采用浓度6.5%的聚合物胶液与浓度2%的有机复合交联稳定剂，按聚合物胶液与有机复合交联稳定剂10∶1.3的交联比，在17.6～40 ℃条件下进行快速成胶试验。试验得出，PLC聚合物交联凝胶成胶时间短，抗污染能力强，与桥堵材料有很好的配伍性，二者配合使用对于封堵黄土层恶性漏失具有很好的应用前景。 |

| Abstract:According to the characteristics of low bottom hole temperature, serious leakage and poor sealing effect by conventional plugging materials and methods for loess layer leakage in Yanchang oilfield, PLC cross-linked polymer gel was developed, which could realize rapid cross-linking in low temperature. Taking polymer gel solution with a concentration of 6.5% and organic compound cross-linking stabilizing agent with a concentration of 2%, according to the cross-linking ratio of 10∶1.3, the rapid gelling test was made under the temperature of 17.6℃～40℃. The test results show that PLC cross-linked polymer gel has the characteristics of rapid gelling, strong anti-pollution ability and good compatibility with bridging material, the match usage of polymer gel solution and organic compound cross-linking stabilizing agent has good application prospects for plugging leakage in loess layer |
