WPS是一种新型的水溶性阴离子表面活性剂,可作为三次采油的驱油剂。华东石油局与安庆石化总厂协作,在储家楼油田开展WPS三次采油矿场试验项目,累计注入WPS驱油剂50.3t,注入浓度为0.5%,注入总液量 10057.70m3 。经现场监测和分析对比,两口观察井均取得了含水率下降、原油日产量上升及原油性质变差的预期效果,累计增产原油506.79t,探索了三次采油的新途径,并具有较明显的经济效益,实现了增油控水和提高油藏采收率的试验目标。

WPS is a new-typed water-soluble anion surfactant,and can be used as an oil-displacement agent for tertiary recovery.Under the cooperation between East China Bureau of Petroleum and Anqing Petroleum and Chemical Factory,a WPS tertiary recovery field test project was developed in Chujialou oil field.During the project,WPS oil-displacement agent was injected by 50.3t cumulatively,the injection concentration was 0.5%,and the total injected fluid amount was 10057.70m3.By field monitoring and comparaive analysis,the expected results of decreasing water content,increasing oil daily production and poor oil properties were obtained in the two observation wells,and the cumulative increased oil production was 506.79t. The field test approached to the new path of tertiary recovery,which had more obvious economic benefits and fulfilled and the test targets of oil increasing,water control and reservoir recovery raising.
