【摘要】 通过近百口全取芯钻井岩芯的岩石学、矿物学、古生物学和地球化学特征的综合研究 ,认为渝东及相邻川东地区的上石炭统黄龙组碳酸盐岩储层主要为古岩溶作用产物。文中简要介绍了黄龙组古岩溶型储层的主要识别标志和岩溶角砾岩的结构 成分分类方案 ,重点对岩溶相、岩溶地貌分区和微地貌单元、岩溶旋回和溶蚀段划分进行了较为详细的描述。在此基础上 ,建立了渝东黄龙组岩溶相、古岩溶地貌和岩溶旋回与古岩溶储层特征和分布关系的综合模式 ,指出岩溶斜坡和岩溶盆地分区中的坡地与残丘微地貌单元为最有利储层发育的部位 ,发育于C2 h2 白云岩段中的上部溶蚀段和下部溶蚀段为最有利古岩溶储层发育的层位更多还原

【Abstract】 Based on the petrology, mineralogy, palaeontology and geochemistry of the carbonate reservoirs developed from the Huanglong Formation of Upper Carboniferous in eastern Chongqing, it is proposed that the reservoirs are a result of palaeokarstification during the middle-late Late Carboniferous. This paper deals with some distinguishing markers concerning the palaeokarst-related reservoirs and the genetic types of karst breccias in terms of their textures and compositions, and the karst facies, palaeokarst morphologic units, karst cycles and solution members of the formation are divided. According to the studies above-mentioned, the relationship between the palaeokarst morphologic units, karst cycles and reservoir distribution has been established, indicating that the favorable loci for the development of palaeokarst-related reservoirs are the hillsides and remnant hills on palaeokarst slope and in palaeokarst basin.更多还原
