摘要

序贯指示模拟和序贯高斯模拟是2种常用的随机模拟方法。在地质统计学反演中,将这2种模拟方法组合使用,先做序贯指示模拟得到岩性数据体,然后进行带岩性遮挡的序贯高斯模拟,最后加上随机反演。用这种方法计算含水饱和度并应用于某地区的精细流体预测中,与常规的流体预测方法叠前AVA同步反演进行了对比,该方法在薄层流体的精细预测方面取得了更好的效果。

Abstract

Sequential indicator simulation and sequential Gaussian simulation are two common methods of stochastic simulation.In this paper,we combined these two simulation methods in geostatistical inversion.We got the data volume of lithology by sequential indicator simulation at first,and then sequential Gaussian simulation with lithology masks was carried out.Finally,we did stochastic inversion.This method was used to calculate water saturation for the detailed fluid prediction in a certain area.The result was compared with that of prestack AVA simulation inversion for fluid prediction.The method was more effective in the precise prediction for the fluid in thin layer.
