滩浅海地区地震勘探存在问题及解决方法

滩浅海地区特殊的地表条件使地震勘探方法变得复杂。其陆地和海洋两种不同特点的地震勘探方法同时存在、混合使用,造成了观测方式的变化、地震资料的差异以及浅海特有的检波器位置移动和海底鸣震等干扰。针对这些问题进行了采集和处理方法研究,形成了一套有针对性的技术方法。试验和应用效果较好。

The problems existed and the methods applied in shallow beach sea seismic exploration

The special surface conditions of shallow beach area made seismic exploration methods more complicated. The simultaneous existence and mixed using of the land and marine exploration methods, which are different in characteristics, made acquisition geometries variable, differences in seismic data, geophone location shifting especially in shallow sea and seabed ring wave, etc. The studies on acquisition and processing methods were performed and a set of techniques for problems above were found out. A good result has been achieved after testing and application was performed.
