摘要
储层常常表现为低速，在井间地震中往往可以观察到导波的存在，其主要特点是在储层附近能量集中，而在围岩中则能量迅速衰减，同时波形具有频散特征。导波特性对储层内部结构与岩性十分敏感，它有可能作为储层描述和采油过程监测的有效手段，本文针对三层简单波导模型进行了频散方程及曲线的计算，并进行了人工合成槽波记录的研究。
Reservoirs may act as seismic waveguides in cross hole surveys.Such guided waves propagate with much of their energy concentrated on the adjacency of reservoirs and behave as strong dispersion in the wall rocks. The properties of guided waves are sensitive to the internal structure of reservoirs. So, guiled waves may be used to provide an effective tool for reservoirs description and monitoring the process of hydrocarbon producton.
