【摘要】 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更多还原

【Abstract】 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.更多还原
