摘要
河口湾由一套变化明显的复杂的亚环境组成。对其相变模式研究表明，河口湾沉积特征及岩相分布受波浪、潮汐和河流三种水动力所控制。塔里木盆地塔中４井区上泥盆统东河塘组下部发育潮控河口湾沉积，由潮控河道复合体、潮坪和潮汐砂坝组成，代表海进体系域沉积，发育下切谷充填型储层。
Estuaries consist of a complex set of intergradational subenvironments that display considerable variation.Study on the facies models indicates that sedimentary features and the distribution of lithofacies are controlled by the interplay between marine processes(waves and tides) and fluvial processes.A tidal dominated estuary discovered from the lower part of Donghetang Fm.(Upper Devonian),well TZ4,Tarim Basin consists of tidal fluvial channel,tidal flat and tidal sand bars and represents the sediments of transgressive systems tracts and incised valley type reservoir.
