为了优化酸液体系缓速性能、增加酸化渗透距离、提高油田生产效率，以丙烯酰胺（AM）、2-丙烯酰胺-2-甲基丙磺酸（AMPS）、甲基丙烯酰胺丙基二甲基全氟丁基乙基碘化铵（FBA）为单体，通过单因素分析法确定了新型含氟共聚物缓速剂的最佳合成条件为：n（AM）：n（AMPS）：n（FBA）为56.3：7.2：1.4、引发剂质量分数为0.35%、反应温度为50℃、pH为6.0、单体质量分数为20%、反应时间为6 h。通过酸岩反应测试，在90℃条件下，与空白盐酸相比，平均酸岩反应速率从3.97×10^-3 g/（cm²·s）降低到5.81×10^-4 g/（cm²·s），且与耐酸减阻剂配伍性良好；在140℃条件下，动态平均酸岩反应速率为2.46×10^-4 g/（cm²·s）。

In order to optimize the retarding performance of acidizing fluid system,increase the acidification penetration distance and improve oilfield production efficiency,a novel sulfonic group-containing fluorocarbon copolymer,which is used for acid retarding agent in oilfields,is prepared by using acrylamide (AM),2-(acrylamide)-propyl sulfonic acid (AMPS),methyl acrylamide propyl dimethyl perfluorobutyl ethyl ammonium iodide (FBA) as monomers.Through single factor analysis method,the optimum synthesis conditions are obtained as follows:n(AM):n(AMPS):n(FBA) is 56.3:7.2:1.4,the mass fraction of initiator is 0.35%,reaction temperature maintains at 50℃,pH=6.0,the mass fraction of monomers is 20% and reaction lasts for 6 h.Acid rock reaction is tested.Compared with blank hydrochloric acid at 90℃,the average acid rock reaction speed can be effectively reduced from 3.97×10^-3 g/(cm²·s) to 5.81×10^-4 g/(cm²·s) by the retardant.The synthetic retardant has good compatibility with acid resistant drag reduction agent,and it still has good retarding performance at 140℃,with an average acid rock reaction speed of 2.46×10^-4 g/(cm²·s).
