| 摘 要： | 根据川东大池干井构造带的钻井岩心和薄片资料，从岩性特征、古生物特征入手，结合区域地质综合分析，将上石炭统划分为三个段。文章详细地研究了沉积环境及演化特点，划分出５种沉积相，并研究了它们的识别标志，及在横向上的展布规律。认为受表生期溶蚀改造的白云岩段是最好的储层段，而碳酸盐砂滩相中的颗粒云岩则是最好的储集岩。

| Abstract: | According to the data of cores and thin sections,the paper classifies Upper Carboniferous ofthis area into three parts combining the analysis of regional Seology,petrography and paleontology.This paper studies the sedimentary factes and evolution in detail,identifies five sedimentary factes: carbonate sandbank,Sulf-lagoon,tidal flat,supratidal evaperiting flat and supratidal gypsum lagoon,givesthe recosniration critcria and discusses the distribution of the factes.The paper indicates that the dolostone leached during epidiagenesis is the best reservoir.The grain dolostone developed in carbonatesandbank is the best reservoir rock. |
