【摘要】 为了研究分形维数与低渗透油田岩石微观非均质性的关系及其对开发效果的影响。从理论上研究了常用的4种分形模型之间内在的联系,并利用压汞毛管压力数据计算了L低渗透油田储层岩石的分形维数,并将分形维数与其它描述岩石非均质性的参数进行了对比。在此基础上,研究了平均分形维数对宏观开发效果的影响。结果表明:平均分形维数越大、非均质性越强、产量越低、含水率越高。分形维数对工程师分析油藏岩石微观非均质性有一定参考价值。更多还原

【Abstract】 In order to study the fractal characterization of the heterogeneity in low permeability rock and its effect on production performance.The four fractal models were derived theoretically and found to be interelated.Using model ?,fractal dimension of core samples with low permeability can be calculated from L oil reservoir.Comparison of fractal dimension with other parameters used to characterize heterogeneity was conducted.The results demonstrated that the greater the fractal dimension,the greater the heterogeneity of the rock,the lower the oil production,and the greater the water cut.The fractal dimension would be helpful for engineers to characterize the heterogeneity of reservoir rock.更多还原
