冀中坳陷宝坻—桐柏镇变换带形成机制与油气意义
THE FORMING MECHANISM OF THE BAODI-TONGBAIZHEN TRANSFER ZONE IN THE JIZHONG DEPRESSION AND ITS OIL-GAS BEARING
摘要
Abstract
Based on the 3D seismic data, through structural section interpretation, fault throw calculation, structural evolution analysis of balanced section and classification of transfer zone types, the formation mechanism of the Baodi-Tongbaizhen transfer zone in the Jizhong Depression is studied in this article.The results indicate that: the Baodi-Tongbaizhen transfer zone is classified as synthetic collinear-type with horst and transfer fault as the main internal structural styles, while the Hupoying fault and the Yangshuiwu fault provide the conjugate accommodation.The Baodi-Tongbaizhen transfer zone acted intensively in Es4 because of the maximum differential extension, and its active intensity decreased gradually in Es3-Es1.However, the transfer zone fell into weakening again in N-Q after strong reaction in Ed.Hydrocarbon source rocks and traps developed respectively in the strong and weak structural regions on the two sides of the transfer zone, and the transfer faults connected with source reservoirs, which makes the area a favorable oriented region for oil and gas exploration.关键词
