摘　　要：华池油田H152区为低孔低渗油藏,已进入开发中后期。本文分析了华池油田长3储层地质特征和沉积微相特征,认为其属于三角洲前缘和前三角洲亚相沉积,并详细分析了区内出现的三角洲前缘水下分流河道、分流河道间湾、河口坝、远沙坝和前三角洲泥等微相的岩性和电性特征。采用序贯指示模拟方法建立了研究区沉积微相,应用序贯高斯方法建立储层参数模型,为成功挖潜剩油提供依据。The Chang3 oil measures in the H-152 block of the Huachi Oil Field are assigned to the low-porosity and low-permeability reservoirs in the middle and later stages of the oil field development. Judged from geological and sedimentary features, the Chang3 oil measures dominantly consist of the delta front and prodeha subfacies deposits including the subaqueous distributary channel, interdistributary bay, channel mouth bar, diatal bar and prodeha mud microfacies. These sedimentary microfacies are constructed by using the deterministic method, and the modeling of the reservoir physical properties are proposed by using the sequential Gaussian similation. This model is helpful to the further development of the H-152 block of the Huachi Oil Field.
