黄骅坳陷孔南地区孔店组孔二段物源区分析

Provenance analysis of the second member of the Kongdian Formation in the Huanghua depression

摘要: 本文以黄骅坳陷孔南地区孔店组孔二段为研究对象,根据砂岩骨架成分、重矿物特征、砂体分布体系和地震剖面等资料,对区内孔二段的物源区及其母岩性质、物源方向进行了系统研究。结果表明,孔南地区孔二段沉积物主要来自盆地东部和西部,东部物源区为徐黑凸起和埕宁隆起,西部物源区为沧县隆起。

Abstract: Significant quantities of oil occur in the second member of the Kongdian Formation in the Huanghua depression. The emphasis of the present paper is placed on the provenance, attributes of the parent rocks and sediment supply direction in terms of sandstone compositions, heavy minerals, sandstone distribution and seismic profiles. The detritus in the study area are believed to come mainly from the Xuhei and Chengning uplifts in the eastern part, and Cangxian uplift in the western part of the basin.
