摘　　要：针对海拉尔盆地贝尔凹陷布达特群潜山裂缝储层特征,从构造特征角度出发,在储层裂缝发育程度与上覆地层厚度、储层与上覆地层接触关系的定性分析基础上,采用储层顶面构造曲率方法定量描述储层裂缝的分布规律;在地震反射能量、地震反射连续性与储层裂缝定性分析的基础上,采用地震吸收系数方法定量预测了储层裂缝发育区,预测结果有效地指导了油藏评价部署和开发方案设计。Considering characteristics of fractured reservoirs in buried hill in Budate Group of Beier Sag in Hailaer Basin, and starting from structural characteristics, this paper characterizes fracture distribution rules quantitatively using top surface structure curvature method based on qualitative analysis on relation between reservoir fractures development degree and overlapping formation thickness and contact relation between reservoir and overlapping formation. On the other hand, based on analysis on seismic reflection energy, seismic reflection continuity and reservoir fractures, it quantitatively predicts reservoir fractures development area using seismic adsorption factor method. Prediction result directs effectively reservoir simulation deployment and development plan design.
