摘要
从VSP资料高保真处理和高分辨率角度出发,结合地震波的传播规律,通过震源子波能量归一化来消除记录中的激发能量差异。以零偏VSP采集过程记录到的震源子波作为参考,结合广义S变换进行VSP资料的吸收衰减补偿,以使所采集的资料获得更高分辨率,达到精细划分薄层的目的。对某一实际零偏VSP资料,利用震源子波进行了激发能量差异处理和吸收衰减补偿,改善了资料的品质,提高了资料的分辨率。
In Zero-offset VSP acquisition,the source wavelet can be recorded. Combining the high fidelity processingand high resolution of VSP data with seismic wave propagation:the source wavelet can be used to eliminate thedifferences in excitation energy. The wavelet can be used as a reference source for information on the absorption ofVSP attenuation compensation with Generalized S-transform,so that data collected can be more higher-resolutionto divide thin-layer well. For the source wavelet of a real zero-offset VSP data,the excitation energy is treated andthe absorption attenuation is compensated with the source wavelet. The results show that the quality and resolutionof original data are greatly improved.
