摘要
在地震资料处理中,可以使用井控地震处理技术,即通过井资料求取球面扩散补偿因子和Q补偿因子。在获得的Q值附近进行扫描,将不同Q补偿的偏移剖面与井资料进行匹配分析,最终获得精确的Q值。实际资料真振幅恢复和Q补偿结果表明,该方法有效地实现了地震资料真振幅恢复和Q补偿,并取得了满意的结果。
In the processing of seismic data, the technique of well-controled seismic data processing can be used. The steps include obtaining spherical spreading compensation factors and Q compensation factors from well data, scanning around the obtained Q values, and then making an analysis by matching the well data with the migration profiles that are processed by different Q values. Finally, an accurate Q value is obtained. The results of true amplitude recovery and Q compensation of the actual data show that this technique is effective.
