Three-Dimensional Sedimentary Microfacies Modeling in Chunguang Oilfield -a Case of P2 Block

摘要

Reservoir microfacies is an important factor affecting the reservoir heterogeneity, and it is significant to accurately predict reservoir microfacies distribution in order to improve oil and gas recovery. The stochastic reservoir modeling method has a strong geological suitability. The reasonable choice of the stochastic modeling method can effectively improve the accuracy of modeling. During the sedimentary facies modeling, sequence indicator simulation is used to characterize the spatial distribution of different microfacies with different variogram, to reproduce the complex microfacies spatial distribution.
