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.
