依据地表一致性模型及其假设条件,本文在进行地表一致性分解时,采用共轭梯度迭代方法在时间域求解。通过对求解的地表一致性分量进行分析,认为进行地表一致性谱分解时应采用四分量进行求解;而进行地表一致性校正处理时,采用炮点分量、接收点分量及共炮检距分量计算反褶积因子来消除地表条件对地震记录的影响较为合理。实际资料处理结果表明,采用本文方法可以有效地消除因地表条件等因素引起的反射振幅畸变。本文方法具有处理速度快,抗噪能力强且处理效果显著的特点。
According to the surface consistency model and its assumptions, this paper uses conjugate gradient iterative method to solve in the time domain when performing surface consistency decomposition. By analyzing the components of the surface consistency, we think that the four components should be used to solve the surface-consistent spectral decomposition. When the surface consistency correction is performed, the components of the shot-point, the receiving-point component and the common-offset component are calculated Deconvolution factor to eliminate the impact of surface conditions on the seismic record is more reasonable. The actual data processing results show that the method proposed in this paper can effectively eliminate the reflection amplitude distortion caused by factors such as surface conditions. This method has the characteristics of fast processing speed, strong anti-noise ability and remarkable processing effect.
