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.

One was that research objects were ruleless and dishevelled. Another was that research target was reducing Ommission Error of change parcel. The Distance Discriminate Analysis was meliorated in the paper to get better recognizing effect. One was turning the question of change parcel to the question of standard land type. Another was making strict regulation. This improved Distance Discriminate Analysis is not only visual and briefness, but also easy operational.
