摘　　要：酸化压裂的效果一般通过酸蚀裂缝的有效长度及裂缝的导流能力来进行评价,酸蚀缝长越长,能够沟通更远距离的储层。本文通过软件模拟分析计算不同地质及工程参数下酸蚀裂缝的有效长度,并通过数学分析方法求得各参数对酸蚀缝长影响程度的大小排序为:酸液用量,排量,孔隙度,密度,渗透率。得到酸蚀缝长的主控因素为酸液的用量。The effect of acid fracturing is generally evaluated by effective length and conductivity of acid etching fracture.The longer the acid fracture is,the farther the reservoir can be connected.In this investigation,the effective length of acid etching fracture under different geological and engineering parameters was calculated and analyzed by software simulation,and the order of influence degree of each parameter on effective length was obtained through mathematical analysis as follows:acid dosage,displacement,porosity,density and permeability.The conclusion shows that the key controlling factor to affect effective length is acid dosage.
