摘要
The oilfield development of Wangzhuang Region in Panlong Oilfield has entered the high water-cut period.The oil production declines quickly and the reservoir heterogeneity is serious.Through analyzing the discretions and their correlation of five parameters of Chang 2 reservoir,three parameters such as clay content,porosity and FZI are chosen as classification parameters, which can objectively reflect the geologic features of poor physical properties and strong heterogeneity for low porosity and permeability reservoir.The Chang 2 reservoir is divided into four flow units including Type A,B,C and D by using the cluster and discriminatory methods.The lithology,physical property,sedimentary microfacies and distribution of four flow units are analyzed. The results show that different flow units have different seepage and reservoir ability.Therefore,the different development methods should be adopted according to the different flow units of reservoir.
