摘　　要：油藏地质模型是将油藏各种地质特征在三维空间的变化及分布定量表述出来的地质模型,是对油气藏的类型、几何形态、规模、油藏内部结构、储层参数及流体分布的高度概括。它由圈闭结构模型、储层地质模型和流体分布模型3个部分组成,其核心是储层地质模型。对油藏地质模型的研究,国外从20世纪60年代初期开始,经历初步认识、快速发展和成熟3个阶段,逐渐形成了一套完整的理论方法和技术手段;国内研究起步较晚,在跟踪国外研究的同时,逐步探索并形成了适合于我国陆相储层的随机建模体系。纵观国内外研究成果,地质建模的发展趋势将是最大限度地挖掘地震资料信息,以期与测井资料的有机结合,并有机地利用随机模拟。Reservoir model quantitatively describes the change and distribution of 3D geological characteristics and generalizes the type, geometry, scale, internal structure, reservoir parameters and fluid distribution of oil and gas accumulation. The model is made up of three sub-models: trap structure model, reservoir geological model and fluid distribution model, with reservoir geological model being the core model. Since early 1960s, the study of reservoir geological model had experienced three phases: preliminary understanding, rapid development and mature phase, and an integral set of theoretical methods and techniques have been generated. However, domestic study started late. At the same time of following the tracks of foreign study, a stochastic modeling system for continental reservoir has been formed. Viewing from the research achievements worldwide, the tendency of reservoir geological modeling would be to give full play to seismic data in expectation of integration with well logging data and to make use of stochastic modeling.
