浅层地球物理方法在广西钦州湾-北海海域断层探测的应用

Application of Shallow Geophysical Method to Detect Active Fault in Nearshore of Qingzhou Bay-Beihai

采用浅地层剖面法、单道地震方法和高分辨率2D地震等地球物理方法对广西北海-钦州湾近岸海域的活动断层进行探测。结果证明,浅层地球物理方法在研究活动断层的位置、产状与形态上均具有很好的作用。针对海域干扰因素多环境复杂等不利因素,通过采用新的数据处理方法技术,取得了理想的探测效果,为今后开展断层的探测与研究提供了借鉴。

The comprehensive geophysics methods to detect active faults of the sea area in Qinzhou Bay Beihai, Guangxi Province is used. The experiment proves that using the geophysics methods such as sub-bottom profiling, single-channel seismic, high-resolution 2D seismic prospecting to study the position and form of active fault is feasible. The good effect has been gotten on active fault. In view of the disadvantages such as many interfering factors and complex marine environments, some new data processing methods and technology are used. The obtained idea survey effect can be used for reference in active fault detection.
