黄骅坳陷徐杨桥-黑龙村潜山带逆冲构造的发现及其意义
|
摘要
利用研究区高品质的地震资料和测井资料 ,解释出了数条逆冲断层 ,重点分析了黄骅坳陷徐杨桥 -黑龙村潜山带逆冲构造的分布、几何特征、成因及发现逆冲构造的意义。这些逆冲断层具有切割深、断距大、剖面宽度大的特点。徐杨桥 -黑龙村潜山带逆冲断层形成于燕山早期 ,郯庐断裂左行走滑是断层形成的主要动力
The paper discusses mainly the distribution, geometric features and genesis of thrust structures in Xuyangqiao-Heilongcun buried hill belt in Huanghua depression and the significance in discovering them. Several thrust faults are interpreted with high quality geologic data and well-logging data collected in our research work in the study area. These thrust faults are found in the study to be characterized with deep dissection, big separation and major width of the section. It is believed that above mentioned thrust faults were formed in the early Yanshanian due to the chief motive force of left strike-slip of Tanlu rift. The discovery of the thrust structures in Xuyangqiao- Heilongcun buried hill belt in Huanghua depression is of great guiding significance in oil and gas exploring in Dagang oilfield.
