Geostatistical inversion can combine the advantages of two aspects: high horizontal resolution from deterministic seismic inversion and high vertical resolution from geostatistical simulation. Therefore, it becomes a new high resolution seismic inversion method. The method uses Bayesian inference to determine a posteriori probability density function of reservoir parameters based on seismic data, well logs and geostatistical information. Then, reservoir parameters are sampled and estimated using MCMC. The results have high resolution, including lithology, porosity, saturation and volume of shale et al., which can be used for reservoir evaluation, geological modeling and reservoir simulation. In this paper, the principle and workflow of geostatistical inversion based on Bayes-MCMC algorithm are firstly introduced. Then the integrated research of seismic inversion, geological modeling and reservoir simulation based on geostatistical inversion are applied to the development of Marine reservoirs in the South China Sea. This method improved the accuracy of geological modeling and efficiency of reservoir simulation.
