摘要(Abstract)：

为深化川中南部洗象池组的勘探开发,以川中南部地区为研究区,以上寒武统洗象池组为目的层,利用岩心观察、薄片鉴定、测井、地震和孔渗实验测试等方法,分析上寒武统洗象池组优质储层台内滩亚相的分布特征。结果表明:洗象池组为局限台地沉积环境,发育台内滩、台坪和潟湖亚相。风化壳岩溶的改造及后期的埋藏溶蚀和构造裂缝优化使台内滩亚相成为相对优质储层。洗象池组洗二段和洗三段是台内滩主要发育层段;东部地区发育大面积分布的台内滩,西部地区滩体发育面积小且零星分布。台内滩亚相为潜在优质储层相,东部地区为有利勘探区。

关键词(KeyWords)：川中南部地区;洗象池组;局限台地;台内滩;相对优质储层
