摘要
从达西二维产量公式出发 ,研究储层产能的理论方程 ,通过相对渗透率与含水饱和度的函数关系为纽带 ,导出油气储层产能与储层有效孔隙度、渗透率以及电阻率之间的多元关系式 .在此基础上 ,结合测井学的基本理论 ,将其作为储层产能综合评价的参数 ,采用灰色系统理论建立了储层产能预测系统 .该方法不仅可以综合定量地评价储层产能的分类 ,还可以通过关联度给出评价结果的可靠程度 .最后给出此方法用于辽河油田滩海地区海南构造带东营组三段储层的油气产能预测一个的实例 .
In this paper, the theoretical equation of the reservoir's production capacity is studied from the Darcy's two-dimensional production equation. The complicated relation between the production capacity and effective porosity, permeability, resistivity is established, through the functional relationship between relative permeability and water saturation. Based on the above studies, combining with the log basic theories, we approach the way of predicting the reservoir's production capacity using log data. Finally the prediction system of reservoir's production capacity is established by grey relating analysis. This method can not only quantitatively evaluates the classification of reservoir's production capacity, but also gives the reliability of evaluation results by relation degree. The method is successfully for the oil-gas production capacity prediction of the reservoir of the third segment, Dongying Formation, in the Hainan tectonic belt, Tanhai area, Liaohe Oil-field.
