摘要
以砂岩储层为例 ,介绍将三维地震数据综合应用到建立地质统计油藏模型中的方法。该方法可用来定量预测砂岩分布 ,评价砂岩分布图的质量并估算钻探成功率。地震反射振幅转化成波阻抗可作为用地质统计的方法对砂体进行预测的补充。通过对比使用和不使用地震数据评价地质统计模型的结果认为 ,利用地震数据可有效地降低储层预测的不确定性
Taking sandstone reservoir as an example, this paper introduces applying 3D seismic data to geostatistical reservoir model. This method can quantitatively predict sandstone distribution, evaluate the quality of sandstone distribution map, and estimate the success ratio of drilling exploration. The wave impedance converted from seismic reflection amplitude can be used as a supplement to sand prediction from geostatistical method. Through comparison, it shows that the uncertainty of reservoir prediction can be reduced by seismic data.
