摘要

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 con-ventional plugging materials and methods for loess layer leakage in Yanchang oilfield, PLC cross-linked polymer gel was de-veloped, 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.
