Abstract:

As the key in the process of reservoir modeling, facies modeling provides reservoir framework for the simulation of the reservoir parameters. Based on the analysis of several commonly used facies modeling, it was presented that using shale content and comprehensive well log interpretation to reconfigure lithofacies in lithofacies modeling, which is available for the work area without sufficient accurate sedimentary microfacies study. The principle and importance of the variogram were expounded. A set of effective methods was suggested referred to the problems occurred in the process of variogram calculation. The effectiveness of these methods has been proved in practice.
