A simulation method of facies_controlling parameter field was proposed to predict the planar distribution of reservoir property parameters.The basic simulation principles of facies_controlling parameter field were studied.In the complete consideration of influence of sedimentary microfacies on reservoir property parameters,the simulation method of sedimentary microfacies was applied to the simulation of reservoir property parameter field.The linkage of sedimentary microfacies simulation and sequential gaussian simulation has been satisfactorily realized.The simulation result of sedimentary microfacies model can be directly used to control the distribution of reservoir property parameters.Consequently,an idea of microfacies controlling parameters is realized.The application results show that this method is prior to Krigging method in prediction of heterogeneous characters of reservoir planar parameters.
