摘　　要：碳酸盐岩储层由于受沉积环境和成岩作用的影响,往往表现出强烈的非均质性,传统储层“四性”评价已无法满足碳酸盐岩储层表征的要求,要想明确储层本质特征,微观孔隙结构评价成为必然选择。为了了解目前碳酸盐岩储层孔隙结构研究现状,在参阅大量文献的基础上,将目前碳酸盐岩储层孔隙结构评价方法系统分为实验分析法、核磁共振测井评价法、基于分形特征的定量表征法、成像测井孔隙度谱分析法和孔隙结构指数表征法五大类。这些评价方法的使用均存在局限性,要想建立连续、方便及可靠的孔隙结构评价方法,今后还需从岩石导电机理方面深入研究,其中基于岩石物理实验分析及模拟的复杂孔隙导电规律是重要研究方向。Due to the influence of sedimentary facies and diagenesis,the carbonate reservoir shows strong heterogeneity.The relationship between porosity and permeability is complex.The traditional evaluation method of four relations of reservoir can no longer be used to accurately characterize carbonate reservoirs.In order to clarify the essential characteristics of reservoir,the study of micro-pore structure becomes one of the important contents of reservoir evaluation.In order to understand the current research situation of the pore structure of carbonate reservoirs,the current evaluation methods of pore structure were summarized,the methods were divided into five types of experimental analysis method,NMR logging evaluation method,quantitative characterization method based on fractal dimension,image logging porosity spectrum analysis method and porosity exponent characterization method.All those evaluation models had potentially assumptions and conditions when using.In order to establish a continuous,convenient and reliable evaluation method for pore structure,it was necessary to conduct in-depth research from the aspects of electrical conductivity mechanism.And the research on the conductive rule of pore network was conducted based on petrophysical experiment.
