摘　　要：地震模拟（Seismic Modeling,简称SMOL）储层预测技术，可以直接从地震资料模拟出地层的密度、速度、深度、孔隙度、波阻抗、伽马及砂岩含量等十几种储层物性及岩性参数，提供近20种参数剖面。SMOL的输出结果真实、可靠，与钻井结果吻合。SMOL的主要特点是对地层的分辨能力强，它可以分辨几米厚的薄层，是进行储层预测和储层描述的一套有效方法。应用SMOL预测目的层的深度、厚度、孔隙度、岩性变化及含油情况分析均与钻井一致。The seismic modeling (abbreviated as SMOL) could be directly used to provide about twenty kinds of parameter profiles and tens of parameters of reservoir physical property and lithology, including formation density, velocity, depth, porosity, acoustic impedance, gammaray and sand content. The output of SMOL is reliable and matches with the drilling results. Main characteristics of SMOL have high resolution capability of thin bed in few meters. It is considered that it is an effective way for reservoir description. The SMOL technique is proved by successful drilling of strati-graphic oil pools. In fact, the predicted target zone depth, thickness, porosity, lithology variation and oilbearing possibility match with the drilling data.
