Difference in fault characteristics and tectonic evolution between Enping Sag and Huizhou Sag in Pearl River Mouth Basin
-
摘要:
在前人研究基础上，利用珠江口盆地恩平凹陷与惠州凹陷二维地震资料，结合断层活动速率分析方法，研究了凹陷内部断裂体系几何学与运动学差异性。依据断裂特征及其活动性差异，将珠江口盆地北部断裂体系发育演化重新划分为裂陷早期（E2w）、裂陷晚期（E2e）、拗陷期（E3z-N1z-N1h）和构造活化期（N1y-N2w-Q）4个构造期次。同时，依据断层展布规模、活动速率大小及活化时期等研究成果，推测惠州凹陷比恩平凹陷更有利于形成大中型油气田。建议将近EW向和NWW向断层作为后期构造研究的重点。
Abstract:Based on previous studies, using 2D seismic data of the Enping Sag and Huizhou Sag in the Pearl River Mouth Basin, combined with fault activity rate analysis, the difference between geometry and kinematics of fault system in the sags was studied. According to the fault characteristics and difference in fault activity, the development and evolution of the fault system in the north of the Pearl River Mouth Basin could be divided into four tectonic stages: early rifting (E2w), late rifting (E2e), depression (E3z-N1z-N1h), and tectonic activation (N1y-N2w-Q). Meanwhile, based on research results on fault distribution scale, activity rate, and activation period, we speculated that the Huizhou Sag is more conducive to the formation of large and medium-sized oil and gas fields than the Enping Sag. Therefore, we recommended to focus on the late structural activity of faults in the EW and NWW directions.
