摘　　要：应用储层随机建模技术中的三步建模方法对大庆油田萨北开发区北二西西块进行储层沉积微相建模,将沉积微相概率分布、相序研究及沉积微相结构分析三者有机结合,利用多参数协同、分层次进行相约束的方法得到储层随机属性模型。此方法避免了以往所建储层模型逼近计算机或数学"真实"而非逼近地质"真实"的现象,使地质特征认识由定性转化为定量,为后期的储层井间评价、三维定量分析及油藏数值模拟提供准确而科学的属性模型。This paper has built the model of sedimentary microfacies reservoir in Sabei Development Area of Daqing Oilfield by using the method of three-step modeling in stochastic modeling. The probability distribution of sedimentary mierofacies, research of facie order and structural analysis are handed together organically. Using the method of coordination of Multi-parameters and facies constraint by hierarchy can obtain the reservoir attribution model. This method can avoid the phenomenon that the reservoir geological models approximates computerized or mathematic truth, but not geological truth, which makes the recognition of geological characteristics transform from qualitative to quantitative one and provides accurate and scientific attribution model for the later reservoir evaluation, 3D quantitative analysis and reservoir numerical simulation.
