A model for simulating change of reservoir characteristics and crude properties with the expoitation time in eighth unit of Shengli region 2 is developed. Based on this model the production history of the unit is studied with the fine reservoir simulation. The result shows that variations of permeability and crude viscosity with time have a great influence on the remaining oil distribution and recovery. For the running reservoir simulation on long term water flooding oilfield, the variations of reservoir characteristics and crude properties with developing stages should be considered, so that the decision bases of improving recovery for water flooding oilfield can be proposed. By means of the fine simulation for the reservoir of eighth unit, the present distribution of remaining oil and water out situation are obtained. The research results are successfully applied to design and realization of a plan for improving recovery of the eighth unit.

According to five representative plane isoperm map of reservoir for fluvial factes and five representative plane isoperm map of reservoir for delta factes, methods and results for composing the numerical abstract geological models of permeability plane distribution for fiuvial and delta factes are recommended. The model is a big square which is made up of 8x8=64 equal small squares. The permeability of every small small in descending order accorded with lognormal distribution, and its ordinal number corresponds to a fixed place of foe small square. Thus, when the permeability of 50% probability and the coefficient of variation for lognormal distribution are known, one can establish a definite numerical model of permeability plane distribution. The established solid figures show that the models reflect the characteristics of permeability plane distribution for fluvial and delta factes reservoirs very well. Finally, about representativity of numerical abstract geological model and hot prospect of application for meticulous reservoir description and reservoir numerical sedation are discussed.

介绍了应用河流相、三角洲相各5个有代表性的小层平面等渗透率图合成河流相、三角洲相渗透率平面分布数值抽象地质模型的方法及结果。模型是一个每边分成8等份共64个相等的小正方形组成的大正方形。每个小正方形所具有的渗透率由大到小排列符合对数正态分布,并且其序号对应着每个小正方形一个固定的位置。这样,知道模型的渗透率对数正态分布概率50%处渗透率和变异系数,就可以建立起确切的渗透率平面模型。制作的平面渗透率分布的立体图表明模型很好地反映了河流相与三角洲相储集层渗透率平面分布的特点。最后,讨论了数值抽象地质模型的代表性问题和精细油藏描述与精细油藏数值模拟方法的应用前景问题。

According to the discrete material balance equation of control volume,a new numerical scheme based on PEBI grid and CVFE grid is provided,where absolute permeability is in tensor form. Because of PEBI grid's orthogonalization,its discrete equation is similar with that of finite difference method. The mobility coefficient and interface permeability can be calculated as same as finite difference method. For CVFE grid,reduced pressure gradient is approximated using finite difference and finite element methods simultaneously,and a new upstream weighting approach is proposed based on the signal of flow term,which is more reasonable. The final discrete form of CVFE grid is different from that of PEBI grid and finite difference method. Numerical model tests show that the method proposed by this paper is as accurate as nine point finite difference when permeability tensor is in diagonal form, and it can simulate more complicated cases when permeability is in full tensor form. Its application prospect is more extensive in fine detailed reservoir simulation.
