摘要:

以3D地震资料和钻井资料的解释为基础,通过对济阳坳陷深层进行构造地层分析和构造解析,系统阐明了中、新生代各期构造运动在研究区的地质表现,确定出收缩构造系统、伸展构造系统和走滑构造系统等多期构造样式;提出印支期逆冲断层系由多条显著向NE或NNE向凸出的弧形展布断裂系组成;识别出代表燕山主期构造运动的不整合界面(Tgm),确定了J3—K1时期断陷盆地的分布格局;认为印支期逆冲断裂系统是控制本区晚中生代和新生代早期盆地发育的重要的控制性先存基底构造。在区域动力学分析的基础上探讨了该盆地复杂的叠合结构和山脉盆地的转换过程及机制。从盆地研究的角度,揭示了华北东部中、新生代陆内动力学过程,对于研究区油气勘探实践具有重要意义。

Abstract:

 Based on interpretations of the 3D seismic  and well data, we have systematically elucidated the geological representations of Mesozoic and Cenozoic tectonic movements in Jiyang Sag, Bohaiwan Basin. The compressional tectonic system, the extensional tectonic system and the strike slipping tectonic system, which developed in different tectonic evolution stages, have been determined in this paper. The thrusts during Indosinian Movement consist of several arc thrusts protruding to NE or NNE direction, and negative inversion of these thrust controlled strongly the development of late Mesozoic and early Cenozoic basins. The unconformity (Tgm) indicating the main episode of Yanshan Movement has been identified clearly in seismic profiles, and the distribution pattern and the type of late Mesozoic basin in Jiyang Sag have also been determined. Combined with the analysis of regional tectonic dynamic setting, the complicated superposition structure and basinmountain conversion mechanism have been discussed. From the study of tectonic and evolution of sedimentary basin, we have revealed the Mesozoic and Cenozoic intracontinental dynamic process of eastern North China Block, which will be of benefit to the hydrocarbon exploration in the study area.
