摘　　要：乳液分流酸化技术解决了油田储层非均质性强、层间矛盾突出、油井酸化后含水大幅上升、增液不增油的问题。文章通过对各施工井的分流压力增长量、酸化复产后产液含水率等参数对比分析,研究了储层渗透率、岩性、温度、地层流体含水率以及乳化分流液性能对分流酸化效果的影响。结果表明储层渗透率对分流效率影响较大,地层流体含水率越低分流酸化后控水效果越显著,乳液分流酸化技术适用于含水率在60%以下、渗透率在500 mD以下的非均质性强储层。The emulsion diversion acidification technology solves the problems of strong reservoir heterogeneity,prominent interlayer contradiction,water content rising sharply after acidification and no oil increase.In this paper,a comparative analysis of parameters such as the increase in diversion pressure of each construction well and the water content of the produced after acidification and re-production is carried out.The effects of reservoir permeability,lithology,temperature,formation fluid water content and emulsified diversion performance on the effect of diversion acidification are investigated.The results show that the reservoir permeability has a great impact on the diversion efficiency.And the lower water content of the formation fluid,the more obvious the water control effect after diversion acidification.In addition,the emulsion diversion acidification technology is suitable for strong heterogeneous reservoirs with water content below 60% and permeability below 500 mD.
