ZONATION OF STRUCTURAL PATTERN IN THE BOZHONG DEPRESSION AND ITS ADJACENT AREA
-
摘要: 根据渤中坳陷及邻区的平面构造分布特征、剖面构造特征和布格重力异常等方面的资料分析,认为渤中坳陷及邻区构造具有分带性,从西向东可分为3个带:(1)西部凸起带:发育大量的凸起和断裂,凸起和凸起之间以小凹陷相隔,布格重力异常呈不规则团块状;(2)中部凹陷带:由渤中凹陷和辽中凹陷组成,很少发育凸起和断裂,布格重力异常呈等轴斑块状、椭圆状;(3)东部凸起带:由大量的凸起和凹陷相间组成,由于郯庐断裂的影响形成大量的断层,主要为走滑断裂及分支断裂,布格重力异常主要呈线状分布。这种构造分带性受郯庐断裂带的多期构造活动控制,对油气分布具有重要的影响,目前西部凸起带和东部凸起带由于长期处于构造的较高部位,已成为有利的油气勘探区。Abstract: Based on structural assemblages and direction in map view, structural patterns in seismic profiles and Bouguer gravity anomaly in the eastern Bohai Bay basin, we propose that the Bohai basin is characteristic of zonation of structural pattern. It can be divided into three zones from west to east. They are as follows:the western horseback belt, which developed many horsebacks and faults with small sags between horsebacks, and also had Bouguer gravity anomaly in irregular lump; the central sag belt, which was composed of the Bozhong and Liaozhong sags and horsebacks with few faults, and whose Bouguer gravity anomaly took on equi-axised clot and elliptic shape; the eastern horseback belt, which was composed of many interphase horsebacks and sags. Because the Tanlu fault cut through this belt, there developed many strike-slip faults and branch faults characteristic of string-shaped Bouguer gravity anomaly. The zonation of structural pattern is controlled by multi-phase tectonic movement related to development of the Tanlu fault, and this has an important effect on the distribution in the hydrocarbon in this area. The western and eastern horseback belts have become crucial target for hydrocarbon exploration due to their weaker movements and higher altitude.
