Abstract：Seismic stochastic inversion technique is a such inversion method that combines the stochastic simulation theory with seismic inversion,which can effectively improve the vertical resolution of seismic data and fully consider the random characters of subsurface geology that made the inversion results more consistent with practical geological scenario.Taking the results of determinative seismic inversion as soft data and logging data as hard data,the paper uses collocated Cokriging sequential Gauss simulation technique to do inversion of physical changes of reservoir.The studied results of the case in Wenchang 13-1 oilfield showed that the seismic stochastic inversion has higher vertical resolution in comparison with the determinative seismic inversion based on model,it can fully use seismic data in geologic model-building process of reservoir and easily gain good results.
