在前人研究基础上,根据DP(Dykstra-Parsons)系数能定量评价储层非均质性,微网格块的渗透率值粗化后,其等效渗透率的上、下限(Cmin、Cmax)能反映渗透率的各向异性的特点,提出了一种运算速度快和相对有效的网格粗化算法。

1.
In the coarse grid blocks, firstly the probability density function of permeability is calculated by statistical method, then the Dagan's integral equation is used to compute the effective permeability from the calculated probability density function of permeability, finally, the pressure is calculated by use of the effective permeability in all coarse.
在粗网格内先统计渗透率在粗化网格的概率分布,然后由渗透率积分方程利用渗透率在粗化网格中的概率分布计算粗化网格的等率渗透率,再利用等效渗透率计算粗化网格的压强分布。
2.
If there is no resource or sink in the coarse grid block, the numerical computing method of effective permeability of coarse grid blocks has been given,where the fluid flow rate is the same flowing through the coarse grid block as all fine grid blocks in the coarse grid.
在无源汇条件下,根据流过某一个横截面的流体流量等于流过这一横截面内所有精细网格的流体流量之和这一特点提出了粗化网格等效渗透率的计算方法。
3.
if there are not resource or sink in the coarse grid blocks,the 3D solution of the fine grid blocks has been obtained by solving 3D fluid equations in porous media with direct method,and then the effective permeability of coarse grid blocks has been computed by the 3D solutions.
用所得等效渗透率计算了粗化网格的渗流场的压强分布,结果表明渗流方程的三维粗化解非常逼近采用精细网格的解,但计算的速度比采用精细网格提高了100多倍。

补充资料：粗滤网(coarse mesh filter)
分子式：
CAS号：
性质：又称筛网或粗滤网(coarse mesh filter)。系一种截留水中细小污物的预处理设施。作用与格栅相同，通过拦截作用去除水中不能被格栅截留的细小固体，如细小纤维、纸浆、藻类等悬浮物。格网是由不同材质的金属丝编织成的不同尺寸的筛孔网。格网形式有固定框架式、转盘式、旋转式等。
