2)  diameter and height of column
柱径与柱高
3)  Gas column height
气柱高度
4)  oil column height
油柱高度
1.
On the basis of studying basic characteristics of storage layer in meshwork-carpet type hydrocarbon reservoir system,the critical oil column height of oil migration in storage layer is calculated by using theory of secondary hydrocarbon migration and analyzing migration driving force and resistance force.
在研究网毯式油气成藏体系仓储层基本特征的基础上,以油气二次运移理论为基础,通过对仓储层中油的运移动力和运移阻力分析,计算仓储层油运移的临界油柱高度,来研究仓储层运移或聚集油的砂体厚度,判断仓储层内油的运聚状态,结果表明:(1)当仓储层的砂体厚度大于临界油柱高度时,仓储层可以起到输导油的作用,当仓储层的砂体厚度小于临界油柱高度时,仓储层不能运移油,起聚集油的作用;(2)临界油柱高度的值不是绝对的,它受孔隙度、埋深等因素的影响,三者之间有相互补偿的关系,临界油柱高度与孔隙度呈负相关关系,与埋深呈正相关关系。

补充资料:降液管液柱高度
分子式:
CAS号:

性质:又称降液管清液层高度。板式塔降液管内的液柱液面到下层塔板的垂直距离。如图中的Hd(图暂缺)。为保持板式塔正常操作,避免发生液泛,降液管液柱高度不能超过一定限度。一般应满足Hd≤(0.4~0.6)(HT+hw),式中HT为塔板间距,hw为堰高,系数一般取0.5,易起泡物系取0.4,不易起泡物系取0.6。
