在地面地震记录中,反射波旅行时间反映双程旅行时,而 VSP 是在井中不同深度点接收地震波的,所以其反射波旅行时小于双程而大于单程时间,也即VSP 记录在时深转换时不再具有一一对应的关系。本文从 VSP 反射波旅行时的这一特点出发,采用以采样间隔离散的非均匀介质模型,阐述零井源距 VSP振幅处理中,求取离散薄层的层参数,追踪地震波实际旅程,逐层进行扩散补偿和吸收补偿的方法。 In terrestrial seismograms, travel times of reflected waves reflect two-way trips, while VSPs receive seismograms at different depths in the well, so their reflected waves travel less than two-way trips and more than one-way trips, No longer have a one-to-one correspondence. In this paper, based on this feature of VSP reflected wave travel, a discrete inhomogeneous medium model with sampling interval is used to describe the layer parameters of discrete layer in the process of zero source distance VSP amplitude. The actual journey of seismic wave is tracked, Diffusion compensation and absorption compensation methods.
