Fracturing fluid oil displacement agent and fracturing fluid

The invention provides a fracturing fluid oil displacement agent and a fracturing fluid. The fracturing fluid oil displacement agent is prepared from the following raw materials in parts by weight: 6-10 parts of fatty alcohol-polyoxyethylene ether, 3-5 parts of an anionic surfactant, 0.5-1 part of a pH regulator and 30-50 parts of deionized water. According to the fracturing fluid imbibition agent disclosed by the invention, the nonionic surfactant fatty alcohol-polyoxyethylene ether and the anionic surfactant are compounded, so that the salt resistance and the high temperature resistance of the fracturing fluid can be effectively improved, and the fracturing fluid imbibition agent still has relatively good stability and flowability when the temperature is higher than 80 DEG C. 本发明提供了一种压裂液驱油剂及压裂液，该压裂液驱油剂的制备原料包括按重量分计的以下组分：脂肪醇聚氧乙烯醚6-10份，阴离子表面活性剂3-5份，PH调节剂0.5-1份，去离子水30-50份。本发明的压裂液渗吸剂采用非离子表面活性剂脂肪醇聚氧乙烯醚与阴离子表面活性剂进行复配，可以有效提高压裂液的耐盐性能和耐高温性能，在温度大于80℃时，依然具有比较好的稳定性和流动性。
