摘　　要：针对川中南部地区茅口组沉积相钻井沉积相及微相进行研究,且着重研究茅口组重点储层段的沉积微相,以钻井、测井等资料为基础,结合岩芯及镜下薄片观察描述,确定中统茅口组总体为碳酸盐缓坡型台地相,可细分出浅水型缓坡台地、深水型缓坡台地、台内滩亚相,根据岩性进一步细分出沉积微相。结合海平面升降变化,总结出浅水缓坡-深水缓坡沉积模式。In allusion to facies and microfacies can be divided of Maokou Formation in South Central Sichuan Basin,microfacies of the reservoir are specially studied. Using drilling,well logging combined with the core description and slice observation,The facies of Maokou Formation in South Central Sichuan Basin are general ramp carbonate platform,which can be subdivided into shallow ramp platform,shore in platform,deep-water platform,microfacies can be analyzed according sedimentary lithology.Combined with eustatic change of sea level,Sedimentary models of shallow water gentle slope and shallow water gentle slope are summarized.
