用于油藏数值模拟中的非均值场,即可以改变渗透率变异系数,渗透率级差,可用于eclipse、VIP、cmg中皆可使用,本程序的例子是共有7个层,所以输入数据有7个层的原始渗透率场。-Reservoir simulation for the non-mean field, that can change the permeability coefficient of variation, differential permeability, can be used in eclipse, VIP, cmg in can be used, examples of this procedure is a total of seven layers, so there is input data the original seven-story market penetration.

加强肋
理想的设计
为了克服壁厚大可能引起的问题,使用是一种可减少壁厚并能增加刚性的有效方法。
一般来说,部件的刚性可用以下方法增强
增加壁厚;
增大弹性模量(如加大增强纤维的含量);
设计中考虑。
如果设计用的材料不能满足所需刚性,则应选择具有更大弹性模量的材料。简单的方法是增加塑料中增强纤维的含量。但是,在特定壁厚下,这种方法仅能使刚性呈线性增长。更有效的方法是使用经过优化设计的。由于惯性力矩增大,部件的刚性便会增大。在优化的尺寸时,不但要考虑工程设计应当考虑的问题,还应考虑与生产和外观有关的技术问题。
优化的尺寸
大的惯性力矩可很容易地通过设置又厚又高的来实现。但是对热塑性工程塑料,这种方法常会产生制品表面凹痕、内部空洞和翘曲等问题。而且,如果的高度过高,在负荷下结构将有可能膨胀。出于这种考虑,必须在合理比例内保持的尺寸(见图1)。-stiffened ideal for the design of large thickness overcome the problems that may arise. use of a reduced wall thickness and rigidity can increase the effective method. In general, the rigid parts of the following methods can be used to enhance increased thickness; increased elastic modulus (such as increasing fiber content); Design considerations. If the design of the materials used can not meet the rigid requirements, they should have a greater choice of elastic modulus of the material. The simple way out is to increase plastics reinforced fiber content. However, in s
