摘　　要：本文将甲酸(有机缓速酸)+醋酸(铁稳剂)+表面(OTB)活性剂(缓蚀、杀菌、粘土防膨)+YS-A活性剂(防蜡、降粘、润湿)+HCl(盐酸)+HF(氢氟酸)的试剂配方用于七里村油田项目进行复合酸液体系吞吐试验,结果显示其正常生产天数有所延长,产量有所增加。表明复合酸液体系吞吐对低效水平井补能增产起到一定的效果。In this paper,the reagent formula of formic acid(organic slow acid)+acetic acid(iron stabilizer)+Surfactant(OTB)active agent(corrosion inhibition,pasteurization,clay swelling prevention)+YS-A active agent(wax prevention,viscosity reduction,wetting)+HCl(hydrochloric acid)+HF(hydrofluoric acid)was used in Qilicun Oilfield project to carry out huff and puff test of compound acid system.The results showed that the normal production days were extended and the output was increased.The results show that huff and puff of compound acid system has a certain effect on the stimulation of low efficiency horizontal well.
