摘　　要：目的相控储层建模技术是当前提高地质建模精度、实用性很强的新技术,其关键是准确地建立储层沉积(微)相空间展布的数字模型,进而模拟储层属性参数的空间分布规律,为油藏数值模拟、剩余油预测研究打下坚实的基础。方法应用多参数协同、分层次约束的方法,从沉积(微)相形成与演化的成因角度建立沉积相带的地质模型,以沉积相带的时空间展布特征对安塞油田长2河流相储层建模过程进行了约束。结果通过相控技术得到的储层模型,能真实地反映储层的非均质特性和砂体的连通性,并能较准确地模拟地下含油气储层的属性分布规律,同时为油藏模拟、剩余油预测及挖潜调整提供了可靠的依据。Aim Reservoir modeling technology controlled by sedimentary facies is a practical new technology which can improve the accuracy of geological modeling greatly. The key point is to establish an accurate digital model for spatial distribution of reservoir depositional micro - facies. Furthermore, to simulate the spatial distribution patterns of reservoir parameters, laying a solid foundation for reservoir simulation and remaining oil prediction. Methods mod- eling for fluvial facies reservoir of the Chang 2 group, Yanchang Formation of the upper triassic in Ordos basin con- strained by the temporal and spatial distribution of depositional facies is studied in this paper. On the basis of the depositional facies model constructed by toughly consideration of the facies formation and origin, based upon appli- cation of multi - parameter coordination and on different level constraint approach. Results show that reservoir mod- el controlled by depositional facies can truly reflect heterogeneity of the reservoir characteristics and connectivity of the sand bodies. Furthermore, depositional facies controlled reservoir model can simulate underground distribution of hydrocarbon - bearing reservoir properties more accurately and precisely, at the same time, it can provide a reliable basis for oil -pool digital simulation, residual oil prediction, adjustment and exploitation.
