Abstract

Abstract: A new method for evaluating pore structure in heterogeneous reservoir was proposed on the basis of mercury injection data and laboratory experiments of nuclear magnetic resonance.The total pores of rock were divided into spherical pores and cylindrical pores by mercury injection data and optimization algorithm of the sphere-cylinder model with restricted conditions.All pores of rock were rearranged and combined according to the radii of cylindrical pores.It is supposed that the compartment pores were divided by sphere-cylinder model in space,the number of sphere-cylinder model and ideal seepage sections were calculated.The seepage sections show good agreement with the index of reservoir quality.This research shows rock pore structures in figures with the sphere-cylinder model.

Key words: lithologic reservoir, pore structure, forward model, nuclear magnetic resonance relaxtion, seepage section, reservoir evaluation

摘要： 应用压汞数据和球管模型的约束优化算法,将岩石的总孔隙分解成管形孔和球形孔.在此基础上,根据压汞的进汞过程,对球管模型的分解结果按管形孔半径的数值进行了孔隙分组的重新排序和合并.假设分组孔隙按球管模型的空间分配,计算了单位体积中球管模型在实际岩样分组孔隙中的数量和理想的渗流截面,其计算结果与储层品质指数的结果一致.应用球管模型的分解结果实现了岩石孔隙结构的图形化再现.
