摘要
储层岩石的孔隙空间具有良好的分形特征,孔隙结构的分形维数可以定量描述孔隙结构的复杂程度和非均质性。本文应用分形几何原理,对镇泾油田延9低渗透储层岩石的孔隙结构进行了研究。得出储层砂岩孔隙分形维数同孔隙半径呈良好的对数关系。认为孔隙结构分形维数越大,孔隙结构的复杂程度越强,非均质性越强,储集性能越差,反之亦然。
Aim: the can To describe quantitatively the complexity and heterogeneity of pore structure based on fractal dimension.Methods: According to the principle of the fractal geometry,the pore structure of low permeability reservoir rocks in Yan9 member of ZhenJing oilfield.Results: The Logarithmic Relation between fractal dimension of reservoir rocks can be set up.Conclusion: it shows that the bigger fractal dimension,the complexity of the pore structure become stronger,and the same as reservoir heterogeneity,it...
