均匀倾斜层状地层中地震波球面扩散补偿方法研究

A study on seismic wave spherical spreading compensation method in homogeneous tilted bedded formation

在分析地层深度、炮检距以及地层倾角变化对球面扩散补偿因子影响的基础上,总结了不同因素对补偿因子影响的趋势,以及资料处理中常规球面扩散补偿方法的应用条件.实际应用效果表明,该方法能更加合理的保证不同深度地震信息能量的均衡程度,提高资料的可信度.

The paper analyses the effect that depth of stratum source-detector distance and stratum angle bring to spherical spreading compensation gene, and summarizes the tendency that three parameters affect compensation gene. It elaborates the condition that routine spherical spreading compensation method applies in data processing. Application result shows that the method can more rationally ensure the isostatic energy at the different depth, and improve the credibility of seismic data.
