Abstract: Reservoir geological model is the core of the geological model of the reservoir, is the specific characterization of reservoir characteristics and heterogeneities in the three-dimensional spatial distribution and change. Reservoir modeling is actually establish reservoir properties of reservoir parameters characterizing the three-dimensional spatial distribution and change models. Reservoir parameters include porosity, permeability and oil saturation, reservoir thickness. The purpose of the establishment of reservoir parameter model is through quantitative research on porosity, permeability and thickness of the reservoir, precisely defined spatial location and distribution of favorable reservoir, which directly provide direct the development and adjustment of oilfield development plan geological basis.
