摘要
地层吸收衰减效应是影响地震勘探分辨率的重要因素之一．它主要影响地震反射波中的高频成分，使地震勘探的分辨率降低４０％．文中研究了地层吸收衰减效应的理论机制，并用计算机模拟技术分析了不同地质模型下地层吸收衰减效应对分辨率的影响。
The Earth's absorption and attenuation effect is one of the most important factor that affects the resolution of seismic survey. It mainly affects high frequency signal of seismic reflectors, and the seismic resolution can be attenuated by 40 percent. This paper deals with the theory of Earth's absorption and attenuation effect, and the computer simulation technique has been used to study the Earth's absorption and attenuation effect of different geological models. The results can be used as basic theory and reference for properly compensation of the Earth's absorption and attenuation effect.
