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 includeobtaining spherical spreading compensation factors andQcompensation factors from well data,scanning around the obtainedQvalues,and then making an analysis by matching the well data with the migration profiles that are processed by differentQvalues.Finally,anaccurateQvalue is obtained.The results of true amplitude recovery andQcompensation of the actual data showthat this technique iseffective.
