| 摘 要： | 通过对宜昌莲沱上震旦统灯影组的野外剖面踏勘观察描述,研究地层分布及沉积发育特征。渝东彭水廖家槽灯影组剖面主要为一套潮坪环境沉积的白云岩,共划分为3个岩性段、4个三级旋回层序;区内灯影组储集岩以晶粒白云岩、藻纹层云岩和残余砂屑、鲕粒云岩为主。并以野外踏勘观察为基础讨论了储层发育特征、有利储层类型,找出储层发育的控制因素及分布规律,预测储层发育的有利地带。得出储集空间类型主要有:晶间溶孔、溶洞、裂缝等,属于白云岩储层和古岩溶型碳酸盐岩储层。以此为基础预测出该相带控制的研究区的物性特征较好,储层类型较好。

| Abstract: | According to the exploriation of the Yichang-Liantuo-Dengying Upper Sinian sedimentary strata distribution and development characteristics;Liaojiacao Dengying Group,Pengshui Yudong,which are sections mainly in tidal-flat environment,dolomite deposits were mainly divided into three lithologic,four third-class cyclic sequences.Region Dengying reservoir rock mainly take grain dolomite,algal laminae dolomite and residual sand debris,oolites dolomite.We use them as basis for discussing the characteristics of res... |
