While the retrofit system is applicable to most production scenarios, it has found the most applications to date in steam-assisted gravity drainage (SAGD) Wells.

该装置可以用于多种生产情况，但是其在蒸汽辅助重力泄油(SAGD)系统中使用时效率最高。

Compared with gravity drainage system, it has the advantages of small pipe diameter and installing space, non-sloped suspended pipe, less sewage connecting and underground pipes and etc.

与重力排水系统相比，具有管径小、管道安装要求空间小、悬吊管无坡度、下水道连接管和埋地管少等优点。
