摘　　要：油藏地质模型是一个描述油藏地质特征和储层物性的三维网格数据体,建立高质量的地质模型是进行油藏精细管理和高效开发的关键。文中从地质建模的本质入手,分析了影响地质模型质量的主要因素,提出了地质建模过程中质量控制方法和地质模型可靠性验证方法。按照规范化的地质建模流程,检查基础数据之间是否存在逻辑错误,核实基础数据的准确性;对比分析钻井数据与构造模型的一致性,判断构造模型的质量;分析网格的高度、体积和扭曲度,以及检查上下层之间网格是否交叉,评价网格模型质量;对比分析测井解释数据与属性模型统计规律的一致性,控制属性模型质量;采用抽稀井检验和快速历史拟合方法,检验地质模型的可靠性。实际应用表明,通过地质建模过程质量控制和地质模型可靠性验证,极大地提高了地质模型的质量和数值模拟历史拟合精度。Reservoir geological model is a 3D gridding data volume describing the geology characteristics and reservoir property. Geological modeling with high quality is the key of reservoir fine management and high-efficiency development. This paper analyzed the main influence factors of geological model quality, and put forward the quality control and the checking method of geological model during the process of modeling. According to the normalized process of geological modeling, the logical errors between basic data were checked up to verify the accuracy of data and to check the consistency of drilling data and structural model. The structure model was contrasted to decide the quality of structure model, the height, volume, distortion of every grid were analyzed and the consistency of statistics discipline between log interpretation data and attribute model was analyzed to control the quality of attribute model. The reliability of geological model was checked by the method of decreasing wells and history matching. Field application shows that the quality of geological model and the history matching accuracy are improved greatly by controlling and checking the quality of reservoir geological model.
