油藏描述旨在对油气藏进行全面的综合研究, 描述储层岩性、物性参数的分布是其中十分重要的一项工作。众所周知, 通过测井资料可以来取储层的泥质含量、孔隙度、渗透率和含水馆和度等项参数, 而利用地震资料求取上述参数仍是勘探学家求索的目标之一。本文将就上述问题探讨利用地震资料（速度反演数据）, 结合测并相关分析结果, 横向预测上述参数的方法及可行性, 力争为储层参数描述和储量计算提供较为可靠的基础性资料。

The aim of reservoir description is to study the reservoir comprehensively. Describing thedistribution of reservoir litho1ogy and physical property parameters is a very irnportant workamong them. It is well known that the log data can be used to ca1culate some parameters such asshale content, porosity, permeability, and water saturation of reservoirs. Using seismic data toca1culate the above parameters is still one of the objectives for the explorationists to study. In thepaper, with regard to the problem we make an approach to the feasibility of laterally predicting theabove parameters by using seismic data (velocity inversion data) together with log correlationanalysis results. We strive to provide reliable basic data for the reservoir parameter descriptionand reserve estimation.
