摘    要:运用矿物岩石学、沉积岩石学、储层地质学等多学科理论,结合岩心、薄片、物性分析以及测试分析等多种资料,对开江-梁平海槽南段飞仙关组三段储层岩石学特征、空间类型、孔隙结构特征、物性特征等进行了研究,认为研究区飞仙关组三段储层为鲕滩相沉积,岩性主要为鲕粒灰岩、鲕粒云岩,储集岩大部分表现出渗透率低的特征,鲕粒云岩的孔隙度相对较高;并分析了储层发育的主控因素,认为白云石化作用和溶解破裂作用是影响储层发育的重要因素。

关 键 词:开江-梁平海槽  飞三段  鲕滩储层  物性特征  溶蚀作用

Abstract:By using mineralogy,sedimentology,reservoir geology and multidisciplinary theory,combined with core,slice,physical property analysis,test analysis and other kinds of data,the reservoir petrology characteristics,reservoir space types,reservoir pore structure characteristics,the reservoir physical properties of Fei3 member in the south of Kaijiang-Liangping trough have been studied in this paper.It has been believed that the reservoir of Fei3 member is oolite beach and the lithologies are oolitic limestone and oolitic dolomite.Most of reservoir rocks show the characteristics that permeability is low and porosity of oolitic dolomite is relatively higher.The main controlling factors of the reservoir development have been analyzed and the analysis indicates the dolomitization and dissolution fracture are important factors that can affect reservoir development.
Keywords:Kaijiang-Liangping trough  Fei3 member  oolitic beach reservoir  physical characteristics  dissolution
