根据川东复兴场地区嘉陵江组钻测井、物性资料,对其储层特征进行了较为详细的研究。研究表明,复兴场地区嘉陵江组储集岩以粉细晶白云岩为主,储渗空间以次生粒间、粒内溶孔、晶间、晶内溶孔和裂缝为主,物性较差,多属于裂缝孔隙型、孔隙裂缝型储层。储层纵向上主要发育于嘉二2亚段、嘉一段中,其余各段有少量的分布;平面上,区内南西部储层发育明显好于北东部。
According to the logging data and physical property data of Jialingjiang Formation in Fuxingchang area, eastern Sichuan, the reservoir characteristics are studied in detail. The results show that the Jialingjiang Formation reservoir in Fuxingchang area is dominated by fine pink dolomite. The main reservoir space is mainly secondary grains, intragranular dissolution pores, intergranular dissolution, intragranular dissolution pores and fractures with poor physical properties, Mostly belong to the fracture pore type, pore fracture type reservoir. The reservoir mainly develops longitudinally in Jia 2 2 sub-section and in Jia 1 section, while the remaining sections have a small amount of distribution. On the plane, the reservoir development in the southwestern part is obviously better than that in the north part in the area.
