海上多分量地震资料静校正

在海上多波地震勘探中 ,P SV转换波静校正问题严重影响了转换波资料的处理质量。文中针对中国南海地震地质条件 ,在借鉴前人研究静校正问题的思路及方法的基础上 ,提出了一种在CRP叠加剖面 (X分量 )上人工拾取同相轴 ,并用相应的纵波资料作为判别准则的P SV转换波静校正方法。该方法在莺歌海盆地多波地震资料处理中取得了较好的效果

Static correction of marine multi-component seismic data

The static correction problem of P-SV converted wave has seriously constrained processing quality of converted wave data during marine multi_component seismic exploration. Based on the previous research methods and aimed at the seismic geologic conditions in South China Sea, a static correction method for P-SV converted wave is proposed in this paper. In this static correction, the events are manually picked on CRP stack section (X-component), and the corresponding P-component data are used as a judgement guide. This method has been applied to processing multi_component seismic data in Yinggehai basin, South China Sea, resulting in better effects.
