VSP震源子波应用

摘要

In Zero-offset VSP acquisition, the source wavelet can be recorded. Combining the high fidelity processing and high resolution of VSP data with seismic wave propagation: the source wavelet can be used to eliminate the differences in excitation energy. The wavelet can be used as a reference source for information on the absorption of VSP attenuation compensation with Generalized S-transform, so that data collected can be more higher-resolution to divide thin-layer well. For the source wavelet of a real zero-offset VSP data, the excitation energy is treated and the absorption attenuation is compensated with the source wavelet. The results show that the quality and resolution of original data are greatly improved.%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.
