On the basis of the sublayer correlation and division, the stratigraphic framework is established by regard- ing the top and bottom of the barrier and interlayer as the further divided layers. Under the constraining control of the planar distributing maps of all the layers stated above, the space spreading models are built with the help of the in- tegrating method of deterministic and stochastic modeling. Constrained by the oil-water interface at the well points, and moreover according to the theory of inclined oil-water interface, the model of the fluid distribution is established by means of sequential indicating approach, the model of the reservoir porosity and permeability is built under the control of the reservoir phases, the saturation model is made under the constraint of the two models stated above. The fine characterization and description of the reservoirs and barrier-intedayers are realized, and furthermore the high- precision 3D geological model is presented for the studies on the remained oil and the later adjustment .
