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 .
Based on Darcy’s two-dimensional yield formula, the theoretical equation of reservoir productivity is studied. Based on the relationship between relative permeability and water saturation, the relationship between reservoir productivity and reservoir effective porosity, permeability and resistivity Based on this, combined with the basic theory of logging, it is regarded as a parameter of comprehensive evaluation of reservoir productivity and a reservoir capacity prediction system is established by using the gray system theory. This method not only can comprehensively and quantitatively evaluate the storage This paper also gives an example of the prediction of oil and gas productivity of the third member of Dongying Formation in the Hainan tectonic belt in the Tanhai area of Liaohe Oilfield.
