黄骅坳陷板桥凹陷沙河街组沙二段物源分析

多年油气勘探表明，黄骅坳陷板桥地区沙河街组具有丰富的油气资源。通过传统分析方法，包括古地貌分析、重矿物特征和砂体分布等资料，对区内沙二段的物源区及其母岩性质、物源方向进行了系统研究表明，板桥凹陷沙二段沉积物主要来自盆地北部燕山构造带和西部沧县隆起，且在盆内发生交互混源，而南部港西凸起物源作用较小。此次物源研究对该区下一步进行沉积相带的划分及储层预测具有重要指导意义。

Provenance Analysis of the Second Member of the Shahejie Formation in the Banqiao Sag of the Huanghua Depression

Oil and gas exploration for many years indicates that the Shahejie Formation in the Banqiao Sag of the Huanghua Depression is rich in oil-gas. Systematical study of paleogeomorphology, heavy minerals and sand bodies distribution shows that deposits of the Second Member of the Shahejie Formation in the Banqiao Sag were derived mainly from the Yenshanian structural zone in north and the Cangxian upwarp in west which is of importance to division of sedimentary facies and prognosis of reservoirs.
