摘要

洪湖地区的物源主要来自潜江凹陷东北部,发育三角洲沉积体系中三角洲前缘亚相沉积。在区域沉积相研究基础上,以取心井资料为基础,结合录井、测井等资料通过各种相标志进行比较分析,结合砂体形态、类型,确定其沉积相、微相类型,建立了沉积微相模式。首次运用单砂层沉积微相划分技术对洪湖地区进行了沉积微相研究,指出了微相类型以水下分流河道、河口坝、前缘席状砂为主,其中发育在水下分流河道的砂体为该区最有利的储集砂体,河口坝和前缘席状砂次之。
        Substance source in Honghu Region comes mainly from northeast part of Qianjiang Sag. By studying the facies in Honghu Region, analyzing comparatively all kinds of facies markers based on data including cored wells and well logging and combining sand body forms and types, this paper determines types of facies and microfacies in Honghu Region and establishes sedimentary microfacies model. Single sand layer-based sedimentary microfacies division technique is used for the first time to study its sedimentary microfacies, finding out that its microfacies types consist of underwater distributary channel, estuary dam and leading edge sheet sand among which sand body developed in underwater distributary channel is the most favorable reservoir sand body and the latters take the second place.
