沉积因素在影响储层非均质性的成因、现状和预测方面的重要性,使得沉积相与非均质性的相关关系研究在储层描述和评价方面越来越必要。文中主要从现有物性资料出发,运用权重法统计出沉积相对非均质的影响程度,得到沉积相控制非均质程度的定量方法,为相控模型中非均质展布和预测提供更详细的参考系数。
The importance of the sedimentary element impacting the cause, status and forecast of the reservoir heterogeneity make it more and more necessity to study the relationship between sedimentary facies and heterogeneity. This paper, mainly from the existing data of physical property, makes statistics of the degree that the sedimentary microfacies impact on heterogeneity by method of weighting. A quantitative method about the degree of sedimentary microfacies controlling heterogeneity is obtained. It will offer more detailed parameters for distributing and forecasting of heterogeneity in facies controlled model.
