1) acquisition of zero current
零流接取
2) approaching zero flux
接近零流量法
1.
Basing on the spot practice and the reservoir engineering theory, we take a kind of production method " approaching zero flux" which is mainly used in the high water- cut oil well or the layer.
结合现场实践,从井筒内再次成藏角度提出了“接近零流量法”挖潜强淹层剩余油的一种开采方法,其主要目的是对因特高含水已经或将要废弃的井层采取间歇生产或尽可能降低产液量方法继续动用。
3) external zero-sequence current
外接零序电流
1.
Finally,the paper describes the reason and function of using external zero-sequence current.
2008年4月在对一条新上的110kV线路保护进行测试时,发现零序保护一直拒动,通过对二次接线、试验仪器及装置本身的仔细检查,排除了二次接线、仪器及保护装置本身的问题,最终发现设计二次接线与典型接线不同,导致外接零序电流未接入保护装置,从而引起了零序保护的拒动。
