摘要 潜江凹陷东部斜坡物源主要来自西部及西北部,王场东、黄场地区潜江组三角洲前缘的水下分支河道、河口坝、席状砂发育,其中以水下分流河道和河口坝砂体的油井产量较高,尤其是在水下分流河道和河口坝的储层中。经研究认为:东部斜坡仍存在较多的水下分流河道及河口坝成因的含油砂体,对于井控程度差或尚未钻井的区块,有较大滚动扩边和油气勘探潜力。 Based on the analysis of drilling and logging data along with speculations about reservoir stratum, this paper proposed that the sediments in the east slope of qianjiang depression basin are mainly from the development of submerged branch channel, mouth bars and Sheeted sands in the front delta formed by eastern wangchang, huangchang and qianjiang located in the west and northwest. The reservoir stratums of the said submerged branch channel and mouth bars are the major contributor to the oil output. As showed in the research that there remain quite a few oil--bearing sand bodies related to submerged branch channel and mouth bars in the east slope and there is more potential of rolling extension and oil--gas exploration in those areas which are not well controlled or drilled.
