RESERVOIR MODELING COMBINED TECHNIQUE IN POOL DESCRIPTION

The reservoir geological model is an important compositional part of current pool description.Model-build technique focus on how to characterize reservoir so that the model accord with the fact.The paper points out that the reservoir model——a duality model composed of structure model and attribute model is a deterministic model built by combining deterministic and stochastic simulation technique.All kinds of simulation methods obey to the factual geosciences character.Four principles are summarized in model-building: Combined principle,equivalent time principle,geological conditions principle,classified levels principle.
