一种洗油剂的制备方法及其应用工艺
摘要：
本发明公开了一种洗油剂的制备方法及其应用工艺，基液由A：10-15%，B：5-10%，C：15-20%，D：5-10%，E：5-10%，F：5-10%，G：5-10%，H：5-10%，水：10-20%重量百分比配比的组份制备得到。洗油剂的基液的制备方法是按照配比，将F和G加入到带加热的搅拌罐中，边搅拌边再依次加入A、B、C、D和E到搅拌罐中并加热至完全溶解，最后加入H，温度控制在80±5℃，保温1小时制备得到。洗油剂是由上述基液用4%NaCl和0.1%CaCl2溶液配制成1%的水溶液，在90℃水浴养护24小时制备得到。洗油剂的应用工艺采用洗油剂与CO2吞吐技术相结合的采油方法，本发明洗油剂洗油效率高达97%以上，进而达到单轮次吞吐可提高原油采收率1%的目的。
摘要（英）：

The invention discloses a preparation method and an application process of an oil washing agent. A base solution is prepared from the following components by weight percent: 10-15% of A, 5-10% of B, 15-20% of C, 5-10% of D, 5-10% of E, 5-10% of F, 5-10% of G, 5-10% of H and 10-20% of water. A preparation method of the base solution of the oil washing agent comprises the following steps: adding F and G into a stirring tank with a heating function according to the proportion; sequentially adding A, B, C, D and E into the stirring tank while stirring, and heating for complete dissolution; and finally, adding H, controlling the temperature at 80+/-5 DEG C, and performing heat preservation for 1 hour to obtain the base solution. The oil washing agent is obtained by preparing the base solution into 1% of aqueous solution with 4% of NaCl and 0.1% of CaCl2 solution, and curing the aqueous solution in water bath at 90 DEG C for 24 hours. The application process of the oil washing agent adopts an oil recovery method of combining the oil washing agent with the CO2 huff-puff technology; the oil washing efficiency of the oil washing agent reaches 97% and above, and the purpose that the single round of huff-puff can increase the oil recovery rate by 1% is further achieved.
