摘　　要：在小层划分基础上，将隔夹层顶和底作为细分层建立地层格架，以所有隔夹层平面分布图为约束条件，采用确定性与随机性建模相结合的方法建立了隔夹层空间展布模型。以井点油水界面为约束条件，按照倾斜油水界面理论，采用序贯指示方法建立了流体分布模型。在储层相控下建立了储层孔隙度和渗透率模型。在流体分布模型和储层孔隙度及渗透率模型的约束下建立了含水饱和度模型。实现了对哈得逊油田东河砂岩油藏储层及隔夹层的精细刻画，为油藏剩余油研究及后期调整提供了高精度的三维地质模型。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 .
