储层岩石孔隙结构特征研究方法综述

岩石孔隙结构特征是影响储层流体（油、气、水）的储集能力和开采油气资源的主要因素，因此明确储集层岩石的孔隙结构特征是充分发挥油气产能和提高油气采收率的关键。介绍了研究储层岩石孔隙结构的方法：室内实验（毛管压力曲线法、铸体薄片法、扫描电镜法及CT扫描法）和利用测井资料（电阻率测井资料和核磁共振测井资料）评价岩石孔隙结构的两大类方法，综合分析这2类方法的优越性和不足，并指出利用电阻率测井资料研究储层孔隙结构特征具有很大的优越性。

Overview of study methods of reservoir rock pore structure

Rock pore structure is the main factor affecting fluid (oil, gas and water) storage and hydrocarbon recovery, so that a thorough understanding of reservoir rock pore structure is critical to improve oil and gas recovery factor. This paper introduces the study methods of reservoir rock pore structure: in - house experiments ( capillary pressure curve method, thin section method, scanning electron microscope, CT scanning method) and logging data (resistivity logging data and NMR logging data) evaluation method. The advantages and disadvantages of these two methods are comprehensively studied. It is pointed out that resistivity logging data is advantageous in reservoir pore structure study.
