英文摘要	The key of applying the random medium theory to seismic exploration is the estimation of random medium parameters (RMP) from seismic data. In this paper, we propose an approach to estimate parameters of stationary random medium from 2D post-stack seismic data. Firstly, the relationship between post-stack seismic data and the impedance model of random medium is established, and the method of parameter estimation of Autocorrelation Function is introduced. Then, by using power spectrum method, the algorithms and procedures on estimating RMP are discussed with an example. Some numerical tests show that the approach is feasible and correct. The test on the real seismic data indicates that the estimated random medium parameters can provide an important reference for further dividing delta sedimentary facies, which reflects the estimation method of RMP is very promising. Comparing with peer-researches, the estimation method in this paper is a true 2D algorithm, especially, which could estimate the autocorrelation angle. This approach based on power spectrum method is obviously efficient and easily understandable but has large errors, and needs to be further improved and perfected in the future research.
