摘　　要：东扶北油田扶余油层浅水三角洲河道类型多样,储层构型特殊,断裂特征和物性分布规律复杂,针对油藏剩余油分布和挖潜及注采调整要求,亟需建立精细三维地质模型,为剩余油分布和油藏数值模拟提供依据。以研究区精细地层划分对比和沉积相研究为基础,通过地质-测井-地震相结合的方法,开展扶余油层储层构型研究,建立储层发育地质知识库。针对扶余油层三角洲河道类型演化特征,提出一种充分利用地质、地球物理等信息,以地质模式为指导、单井河道砂岩分布为硬数据、河流相储层构型为井间约束软数据,采用分级相控、序贯指示模拟建立扶余油层储层地质模型;以测井解释的储层物性参数数据为基础,在储层相模型的控制下,以地震反演数据、物性统计分析数据做约束,采用序贯高斯随机模拟方法建立扶余油层三维属性参数模型。东扶北油田扶余油层油藏三维地质模型精细、客观地表征了三角洲河道储层的三维空间结构,实现了不同类型河道储集体的精细刻画与表征,满足了油藏剩余油分布和数值模拟精确计算的需要。Fuyu reservoir in the Dongfubei Oilfield has various channel types of shallow water delta , special structure , complex fracture characteristics and physical property distribution laws.It is necessary to establish a fine three-dimensional geological model for the requirements of residual oil distribution , potential tapping and injection and production adjustment of the oil reservoirs.It will provide the basis for the residual oil distribution and reservoir numerical simulation.Based on the study of fine stratigraphic division and correlation and sedimentary facies study in the study area , the geological -logging -seismic combination method is used to study the reservoir configuration of Fuyu reservoir and to establish a geological knowledge base of reservoir development.According to the evolution characteristics of the delta channel type in Fuyu reservoir , hierarchical facies control and sequential indication simulation are applied to establishing geological model of Fuyu reservoir based on the full use of geological and geophysical information.It is guided by the geological pattern. Sandstone distribution of the single well channel is hard data , and the fluvial facies reservoir configuration is the soft data for cross-well constraint.Based on the reservoir physical property parameter interpreted by the logging , sequential Gaussian stochastic simulation method is applied to establishing the three-dimensional attribute parameter model of Fuyu reservoir constrained by seismic inversion data and the physical statistical analysis data under the control of the reservoir facies model.The three-dimensional geological model of Fuyu reservoir in Dongfubei Oilfield characterizes the three-dimensional spatial structure of the delta channel reservoir finely and objectively , which realizes the fine characterization of different types of channel reservoirs , and meets the needs of residual oil distribution and accurate calculation of numerical simulation.
