| 摘 要： | 贵州省赤水地区下三叠统嘉陵江组的沉积相属于陆表海碳酸盐台地沉积,本文结合野外露头及井下钻遇情况,划分出了多种沉积相类型,指出滩亚相及云坪微相是本区有利于嘉二1-嘉一和嘉五1 层段油气储层发育的沉积相带,并以"单因素分析多因素综合作图法"为参考,得出嘉二1层段的分岩类厚度百分含量分布趋势,在此基础上对嘉二1-嘉一和嘉五1层段等储层有利层段的沉积相进行了分析.研究表明,除去宝元构造东南部、五南构造、太9井区及雪1井区外,区内大部分地区嘉二1-嘉一层段都发育较为储层有利的云坪微相,部分地区同时发育嘉一段顶部的滩亚相.嘉五1云坪微相的发育情况显示出南东方向较北西方向为好,其中宝元构造中南部最好,旺隆构造次之,雪柏坪构造推测应较好,太和、五南构造较差.台内滩沉积则仅局限于旺隆构造的旺12、旺6井附近. |

| Abstract: | The depositional facies of Lower Triassic Jialingjiang Formation in Chishui area of Guizhou belongs to continental-marine carbonate platform deposition. Based on field outcrop in combination with drill core,this paper divided the sedimentary facies into several types and pointed out that beach subfacies and dolomite-flat microfacies are depositional faices zones in favor of the development of T1j21-T1j1 and T1j51 reservoirs in this area and,using the "single factor analysis and multifactor integration graph... |
