应用分形理论评价碳酸盐岩孔隙结构

Quantitative Evaluation of Pore Structure in Carbonate Reservoirs Using Fractal Theory

研究区块的孔隙型白云岩储集层的孔隙结构评价困难。采用铸体薄片能直观地反映岩石孔隙结构,应用数学方法对其进行定量分析,利用分形理论对储层孔隙结构进行研究,结合岩心物性资料和核磁共振测井资料,建立了根据分形维数定量评价孔隙型白云岩储层孔隙结构的方法和标准。

Due to the heterogeneity of pore dolomite reservoir in the study area,it is difficult to evaluate pore structure. The casting thin sections can directly reflect the pore structure of rock. A quantitative analysis is carried out by mathematical method. The pore structure of reservoir is studied by fractal theory. We think that the method and standard of quantitative evaluation of pore structure of pore type dolomite reservoir on fractal dimension are established in combination with core material and nuclear magnetic resonance logging data.
