| 摘 要： | 地震、测井、岩心以及微量元素资料的分析表明，塔中４井区石炭系东河砂岩段中下部发育有河口湾沉积体系，其主体由潮下潮汐沙坝、滨面、潮坪及河流沉积积组成。河口湾沉积体的垂向序列由一组向上变细的旋回层构成，这种旋回层是由潮下潮汐通道的迁移或摆动造成的，区域上不能进行横向对比。

| Abstract: | An analysis of seismic,logging, cores and elements data demonstrates that an estuary sedimentary system in the middle-lower parts of Carboniferous Donghe Sand member in Tazhong 4 well area,Tarim Basin is made up mainly of tidal bar,shoreface, tidal flat and fluvial deposits.Up-finer cyclothems resulting from the shift of tidal channels constitute the main part of a vertical sequence of estuary deposits. The cyclothems are not used to correlate laterally in region. Nevertheless, overall characteristics of up-finer and retrogradation show that the estuary deposits are accumulated in the process of transgression. |
