摘　　要：对复杂油藏开展数值模拟研究的关键是建立符合油藏地质实际的三维地质模型。常规的数值模拟建模方法考虑的因素简单,无法精确描述诸如断层、微构造、隔夹层、严重非均质储层及流体等复杂油藏的特殊地质现象。针对复杂油藏特征,结合目前数值模拟建模的新技术、新方法,提出在数值模拟建模过程中建立合理描述主要地质要素的控制系统,避免模型中参数分布的不合理,保证数值模拟地质模型最大程度地保留油藏描述的研究成果,反映了地下流体渗流的主要地质特征。General method of numerical simulation modeling considered only simple factors and cannot describe exactly the special geological phenomena such as fault,micro structure, interlayer, seriously heterogeneous reservoir and fluid. Combining with present new techniques and methods of numerical simulation modeling, a control system describing reasonably main geological factors of complex reservoir was presented during numerical simulation modeling. This method can avoid the irrational parameter distribution, ensure the main research results of reservoir description for the geological model of numerical simulation to a greatest extent and reflect the main geologic characteristic of subsurface fluid percolation.
