摘　　要：GL型驱油剂是在保持石油磺酸盐可以使油水达到超低界面张力作用的同时,复合了改善地层流体流动性的功能;做好双河油田GL型驱油剂适应性分析,对延长油田开发期限,稳定原油产量十分重要。室内实验证实,它不但具有良好的表面张力和降低原油粘度的能力,而且与地层岩性及地层流体的配伍性良好,可使剩余油采收率增幅达17．87％左右。GL displacement agent can keep oil - water interfacial tension at ultralow status with oil sulfonate, as well as improve the fluid flowability of formations at the same time. Making a good analysis on oil displacement agent applicability is very important to prolong development period and stabilize crude oil output The experiment result shows the agent not only has good interfacial tension, as well as lower oil viscosity, but also has good compatibility with fluid and lithology of formation, which can increase the recovery of remaining oil about 17. 87%.
