摘　　要：针对实际生产中水平井井身设计及储层渗流机理十分复杂的情况,运用水电相似原理进行电模拟实验对渗流场进行模拟,通过设置不同的参数级别分析各裂缝参数对产能的影响,在此基础上分别分析了单因素的最佳值,并运用正交实验方法对参数进行综合优选。将最终得到的试验结果应用于研究区,增产效果明显。研究成果可为压裂水平井产能和效率的提高以及低渗透油藏的高效开采提供参考。According to the fact that the actual production in the design of the horizontal wellbore and reservoir percolation mechanism is very complex, using similarity principle of water and electricity, we simulated the electric simulation of seepage field by setting different parameters level analysis of the fracture parameters influence on capacity, and on the above basis, we analyzed the best value for the single factor and had integrated optimization of the parameters with orthogonal experiment method. The final result was applied to the study area and the production increased obviously. The achievements can provide the reference for realizing the high efficient production of the fractured horizontal wells and efficient exploitation of low permeability reservoirs.
