层理构造

此外，不同沉积环境中形成的各种层理构造同样对储层渗透性有一定影响。

In addition , a variety of bedding structures formed in different environments has also exerted an effective influence on reservoir permeability .

洞穴砂、泥岩一般呈黑色&棕色高导显示，其中常见图像纹理，解释为各种层理构造；

在分析了流动单元的基本特征后，提出了流动单元的成因分类方案，把流动单元划分为受断层、隔层、夹层、渗透率韵律、层理构造、裂缝及孔隙结构控制的7类流动单元。

After analysing the basic features of flow units , a genetic classification scheme of flow units was suggested . Flow units were classified as seven types controlled by faults , impermeable strata , intercalated bads , permeability rhythm , stratification tectonics , fissures and pore structure , respectively .

根据矿体相对层理和构造关系，可分为三种主要类型。

There are three main types , depending on the relationships of the deposits to bedding or structure .
