摘要: The spatial distribution of sedimentary fades in petroleum reservoirs is major concern due to its influence on the flow regime reservoir, and thereby production oil gas. A class stochastic models, called semi-Markov Random Fields, for facies presented. Semi-Markov Fields are a sub-class Markov Field models. model parameters have, contrast usual with local neighborhood, clear physical interpretation as size distributions homogeneous volumes border relations. can be regarded three dimensional generalization well known chain one dimension. Simulation results both from neighborhood
