摘　　要：由于各储层物性在注水开发过程中都会发生相应的动态变化,因此建立注水开发前后储层物性的动态地质模型,并研究注水开发过程中储层物性的变化规律,对寻找有利区带以及进一步提高油田开发效果具有极为重要的地质意义。以胡状集油田胡七南断块沙三段储层为例,在测井资料综合解释和精细沉积微相研究的基础上,并以沉积微相为约束条件,采用随机建模方法建立了注水开发前后的储层三维地质模型,并通过分析泥质含量、粘土矿物、孔隙度、渗透率这些储层物性的变化规律,得出了储层物性变化的机理,深化了油田高含水期的地质特征认识程度。Because the reservoir physical property was changed dynamically corresponding to the process of waterflooding,it was of great significance in geology to study the law of the reservoir physical property changes by establishing the dynamic geological model of reservoir physical properties both before and after waterflooding to find the favorable area for further improving the effect of oilfield development.By taking Southern Fault Block Hu7in Huzhuangji Oilfield as an example,on the basis of the comprehensive interpretation of logging data and fine study of sedimentary micro-facies,a stochastic modeling method is used to establish 3-D reservoir geological model under the constraint condition of sedimentary mirco-facies,simultaneously,according to analysis on the law of shale content,clay mineral,porosity and permeability changes,the mechanism of reservoir physical property changes is obtained and the understanding of geological characteristics at high water-cut stage is deepened.
