基于振幅法的海上多分量地震勘探方位校正研究
|
摘要
针对采用绕圈悬挂式海底电缆系统进行海上多分量地震勘探的复杂情况,提出了一种称之为振幅法的水平分量检波器在任意随机取向情况下的方位校正新方法。通过对三维理论模型试算和对海上三维多分量地震勘探实际采集数据进行处理,均获得了很好的方位校正效果,表明了新方法的可行性和实用性。
A new method of orientation correction for the horizontal-component in the situation of horizontal-component random orientated, called amplitude method, is put here, aimed at the most complicated situation in multi-component seismic exploration when the multi-component seismic data were acquired using the looped-draped seabed cable system. The satisfied results of orientation correction were obtained, via the testing of 3-D theoretical forward modeling data and the processing of 3-D multi-component seismic field data in this paper, that indicating the feasibility and practicality of the new method.
