摘要
笔者从霸县凹陷整体出发,从构造对沉积作用的控制入手,通过岩芯资料的仔细分析,从岩石颜色、岩性、结构、层理构造等多个方面对岩芯进行了描述,并结合测井曲线特征进行综合分析,初步认为本区沙一上亚段-东营组为典型的二元结构沉积特征,底部沉积物主要由含砾砂岩,砂岩组成,顶部沉积粉砂岩及泥岩,发育辫状河沉积,并且具有多阶性的发育特点,可进一步划分出河床、河道边缘及泛滥平原亚相;沙一下亚段在工区西南部,发育有三角洲沉积。
In this paper, based on the analysis of the whole Ba County depression, the sediment controlled by structure, anatomizing the core data carefully, describing the drilling core from many aspects, such as the rock colour, lithology, structure, bedding, making a comprehensive analysis with well logs characteristics, then the authors considered preliminary that the district Es1-1 and Ed in this area belongs to sedimentary characteristics of the typical dual structure. And the composition of bottom sediments are mainly pebbled sandstone or sandstone, and the top sediments are siltstone or mudstone, which show the developmental characteristic of multi-stage, and can be further divided into a river, river edge and flood plain subfacies. Es1-2 is in the south-west part of this area, developing deltaic deposit.
