摘要: 饶阳凹陷大王庄地区沙三上亚段的层序地层研究表明,该段是一个三级层序,划分为低位体系域、湖侵体系域和高位体系域,低位体系域由 2 个准层序组组成,湖侵体系域和高位体系域各为 1 个准层序组。通过研究低位体系域两个准层序组的沉积体系展布特征,认为该时期发育 3 个三角洲沉积体系。三角洲前缘亚相的水下分流河道和席状砂是有利储集体,并对该区的构造特征和砂体配置关系加以分析,指出了非构造油藏勘探的有利目标。

Abstract: The upper part of the third member of Shahejie formation in Dawangzhuang area in Raoyang sag is a third-order sequence and can be divided into the low stand system tract, the transgressive system tract and the high stand system tract. The low stand system tract is composed of two parasequence sets. Both the transgressive system tract and the high stand system tract are composed of one parasequence set, individually. Through the research of sedimentary microfacies and sandbody distribution of parasequence sets of the low stand system tract, it is found that there are three delta depositional systems in this period. The most favorable sandstone body is the subaqueous distributary channel and sheet bar of the delta front subfacies. According to the structural characteristics and sandbody distribution relationship, the future exploration targets non-structural reservoir in Dawangzhuang area is proposed.

Key words: Raoyang sag, Dawangzhuang area, sequence stratigraphy, sedimentary system, subtle trap
