摘　　要：鄂尔多斯盆地延长组长8是镇原油田的一个重要勘探层位。由于所获得的钻井资料不多,不同微相的储层物性差别大等特点,为了提高随机建模的精度,降低模拟实现过程中的不确定性,提出了运用地质统计学方法,结合测井、岩心资料,在沉积微相控制下的(相控)储层建模方法。首先,运用序贯指示模拟法实现能够表征储层非均质性的沉积微相模型;在沉积微相模型建立好后,进行相控物性参数建模,分小层分微相统计各物性参数的分布特征;然后利用序贯高斯模拟法分别进行模拟,建立研究区的孔隙度模型、渗透率模型和含油饱和度模型等。结果证明此方法建立的模型效果较好,客观反映了地质实际情况,为镇原油田下一步滚动勘探开发提供了地质依据。Chang 8 member of Yanchang Formation is an important explored layer of Zhenyuan oil field in Ordos basin. A method of reservoir modeling constrained by using geostatistics, combining the data of well log and core and considering sedimentary micro-facies is proposed in order to improve the accuracy of the simulation and decrease the uncertainties in simulation. Firstly, the 3D sedimentary micro-facies model is established by using the method of sequential indication simulation. Then, the petrophysics models, including porosity model, permeability model and oil saturation model, are built under the control of micro-facies model by using the method of sequential Gauss simulation, which is that the petrophysics of different layers and different micro-facies are calculated and simulated separately. The geological model proved in this way is effective and it can be used to guide the following progressive exploration and development in Zhenyuan oil field.
