沉积微相在一定程度上控制着储集层参数场。确定沉积微相的边界和分布是准确预测储集层参数的基础。以往这一工作依赖人为的推断，模糊性和不确定性较大。引入地质统计学中的截断高斯随机模拟方法，对沉积微相的平面分布特征进行随机模拟。选用等概率模型，在非均质性极其严重的Ｈ油田沙三中段９砂组５小层４种沉积微相的分布研究中应用该方法，结果表明，该方法能克服因资料不全而引起的模型的不确定性，优于传统手工方法，应用效果良好。图４表１参２（邹冬平摘
Sedimentary microfacies to a certain extent control the reservoir parameter field. Determining the boundaries and distribution of sedimentary microfacies is the basis for accurate prediction of reservoir parameters. In the past, this work relied on man-made inferences, with greater ambiguity and uncertainty. A truncated Gaussian stochastic simulation method was introduced into the geostatistics to simulate the plane distribution characteristics of sedimentary microfacies randomly. This method was applied to the study of the distribution of four sedimentary microfacies in five sub-layers of the 9 sand group in the middle part of the Shahejiexiaohigh H field with extremely high heterogeneity. The results show that this method can overcome the problems caused by incomplete data The uncertainty of the model is superior to the traditional manual method and the application effect is good.
