摘要
川东地区三叠系嘉陵江组一、二段以碳酸盐台地沉积为主,其中发育的粗结构碳酸盐岩分为三类:正常波浪和潮汐作用控制的滩相粗结构岩、风暴浪和风暴流作用形成的风暴相粗结构岩以及快速潮流作用形成的潮沟相粗结构岩。这三类粗结构岩具有不同的岩石学特征。它们是本区嘉一、二段中主要的有利储集岩。滩相粗结构岩的储集性能最好。
Carbonate sediments dominate in the platform in Ⅰ and Ⅱ Members, Jialingjiang formation, Lower Triassic, eastern sichuan basin. The Coarse-textured carbonates which occur in these sediments are divided into three types: (1)coarse-textured carbonates of bank facies comtroled by normal wave and tidal currents; (2) those of storm facies formed by storm wave and currents; (3)those of tidal channel facies deposited by rapid tidal currents. Their characteristics vary in lithology. They are main reservoir beds in Ⅰand Ⅱ Members of Jialingjiang formation. The coarse-textured carbonates of bank facies are best in the reservoir property.
