摘　　要：在室内评价聚表剂溶液性能的基础上,对聚表剂驱矿场应用效果进行了分析。结果表明,相对于同浓度普通聚合物,聚表剂溶液具有更高的黏度和乳化能力,且具有较好的稳定性;在油田矿场应用过程中聚表剂驱有着良好的注入能力,剖面调整作用强,改善了油层的动用程度,水驱后开展聚表剂驱增油降水效果非常明显,聚驱后开展聚表剂驱也可收到较好的增油降水效果。On the basis of evaluating solution characteristics of functional polymer surfactant(FPS) in laboratory,the injection and production data of FPS field tests are analyzed.The results show that FPS solution has higher viscosity,better emulsification and stability than that of ordinary polymer with same concentration.FPS system is of good injection ability and profile adjusting ability in the process of oilfield development,which enhances the used degree of thin and poor oil layers.A good effect of water cut decreasing and oil increasing can be seen in FPS flooding after polymer flooding to some extent and the effect of water cut decreases and oil increases in FPS flooding after water flooding is obviously better than that after polymer flooding.
