| 摘 要： | 在海上多分量地震勘探中，会不可避免地涉及到水平分量检波器的方位确定及其旋转校正问题。特别是当多分量数据采集采用绕圈悬挂式海底电缆系统进行作业时，水平分量检波器的方位校正就显得非常关键和重要。针对最复杂的海上多分量地震勘探情况，探讨了水平分量检波器随机任意取向情况下的方位校正问题，并用三维理论模型记录和实际的海上三维多分量地震数据进行了试算，获得了很好的校正结果。 |

| Abstract: | Orientation determination and correction of horizontal-component receivers is inevitably encountered in marine multi-component seismic exploration. In particular, when the multi-component seismic data was acquired using looped-draped seabed cable system, the orientation correction of horizontal-components will become very critical and important. The problem of orientation correction for random orientated horizontal-components was discussed in the most complicated situations of multi-component seismic exploration. A set of 3-D theoretical forward modeling data and a set of field 3-D multi-component seismic data were tested. Satisfactory results were obtained that indicated the feasibility and practicality of the method proposed in this paper. |
| Keywords: | marine multi-component seismic exploration converted-wave data processing horizontal-component geophone orientation correction model |
