The distributary river course reservoir in the Lower Member of Minghuazhen Formation in an oilfield of Bohai Basin was modeled. The modeling units were divided using the integrated geological modeling method based on seismic, log and geological data. The sedimentary microfacies features of the modeling units were described. The geological knowledge base, including quantitative description of microfacies in every unit, probability function of facies, connection probability of sand body, was established. The geological model of reservoir was proposed on the basis of stochastic reservoir modeling by using an objectbased simulation method.
