摘要
为了给弹性参数反演提供精确可靠的基础数据,在叠前时间偏移的CRP道集(共反射点道集)上,首先对数据体进行可行性评价,然后对资料做进一步补救性校正和剩余补偿处理,采用高密度速度分析技术,重新拾取均方根速度,重新进行动校正处理,从而实现了CRP道集无时差叠加。
To provide accurate and reliable data for elastic parameter inversion,we firstly performed data volume feasibility evaluation on CRP gathers after prestack time migrating.Secondly we carried out remedial corrections and residual compensation processing.And finally we picked RMS velocities with high density velocity analysis technology and implemented moveout correction once more.Zero time difference CRP stacking has been achieved.
