摘　　要：经过多年的注水开发,安塞油田王窑长6油藏现已处于中高含水阶段。储层非均质性严重是导致油区含水上升快、剩余油分布不均的主要因素。因此,本文从基础地质出发,在对油区储层地质和沉积微相进行精细研究之后,建立了反映地下地质体的三维模型,为后期油藏数值模拟中挖掘剩余油分布规律提供了直接的数据体。在建模过程中,采用了基于相元的顺序指示模拟方法建立储层的沉积微相模型,在沉积微相模型的控制下采用顺序高斯模拟方法建立储层的物性参数模型,所建模型与实际地质情况相符,具可操作性。After many years of waterflooding development,the origins of Chang - 6 reservoir in Wangyao district of Ansai oilfield are already at a stage of high water cut.Serious reservoir heterogeneity is main factors of influencing the water cut rising quickly and remaining oil uneven distribution.Therefore,based on the fundamental geology, this paper research on reservoir geology and sedimentary microfacies of oilfield and builds the three - dimensional model reflecting underground geological,which provides a direct date volume for excavating remaining oil distribution rule in Reservoir Numerical Simulation.In the process of modeling,the pixel -based sequential indicator stochastic modeling method is used to build the sedimentary micro facies model in the reservoir.Under the control of the sedimentary micro facies model,physical parameter model is built by means of sequential gauss stimulation method.The model equates with the actual geological conditions,with operability.
