本文从地震、古生物、沉积和测井等多方面的资料入手，用层序地层学方法研究了黄骅坳陷歧北凹陷沙河街组的地层层序，将其划分为两个大层序，即层序Ⅰ（沙三段）和层序Ⅱ（沙二、沙一段）。在每个层序中，又进一步划分出低位、湖进和高位三个体系域，总结了各个体系域的特征，进而指出有利的油气聚集相带和地段。
In this paper, we start with the seismic, paleontological, sedimentary and well logging data, and study the stratigraphic sequence of the Shahejie Formation in the Qibei Depression of the Huanghua Depression by means of sequence stratigraphy, dividing it into two large sequences, that is, Sequence Ⅰ (Es3) and Sequence Ⅱ (Es2, Es1). In each sequence, we further divide the three system domains of low, lakes and highs, summarize the characteristics of each system tract, and then point out favorable hydrocarbon accumulation facies belt and lot.
