储层物性参数处理技术应用实例

Application examples of processing technique for reservoir physical parameters

含油气地层实际是一种双相介质，若用单相均匀介质的理论难以描述地震波在其中传播的复杂地球物理特征。本文介绍的储层物性参数处理技术是根据双相介质理论，综合使用地震、地质资料，以联合调试的迭代方法，把地震记录反演成地震应力，为提取地层物性参数提供一种新的途径。该技术的处理成果能更细致地反映地质构造及岩性变化。近年来，该技术在海上及陆地20余个油田的不同地质条件下使用、验证，并逐步得到完善和发展。及中选用三个有代表性的实例，说明该处理技术解决地质问题的能力。

Hydrocarbon-bearing formation is actually a dual-phase medium. The theory ofa single-phase uniform medium can hardly describe complex geophysical characteristics of seisrnic wave propagating in the dual-phase medium. The processing technique for reservoir physical parameters, based on dualphase medium theory, converts seismic data into seismic stress by using seismic and geological data, and taking joint iterative method. It is a new way of reservoir physical parameter estimation, and its result indicates the variations of geological structure and lithology more detailedly than others do. In recent years, the technique has been used and checked under different geological conditions of more than 20 land and offshore oil fields. It has been perfected gradually. Three typical examples are given here to show its advantage in coping with geological problems.
