摘要
利用正交试验设计方法,对低渗油藏整体压裂时裂缝参数和注采压差对区块最终采收率的影响进行了直观分析和方差分析,得到了裂缝参数和注来压差对最终采收率影响的主次顺序,优选了适合于研究区块的裂缝参数和注采压差的最佳组合方案,对该区块的压裂施工和生产开发设计具有一定的指导意义。
In this paper, production schedule in some low permeability reservoirs with five whole-fractured wells are designed by the theory of orthogonal design of experiments, and are simulated by the reservoir numerical simulator.The influence of hydraulic fracture parameters, including fracture penetration ratio, fracture permeability, fracture width and injection-preduction pressure draw-down on final oil recovery, are analyzed.The order of influence and the optimization of hydraulic fracture parameters are gained separately.At last l regression equations are obtained by the theory of the multivariate straight line regression respectively.
