1)  balance sampling
平衡采样
1.
To realize a true balance sampling receiver and resolve the pulse leakage of template signal in former receivers,a novel sampling-head is proposed.
为实现一种真正平衡的采样接收机,并解决以往接收机存在的采样模板脉冲泄漏问题,设计了一种新的平衡采样头。
2)  balanced oil production
平衡采油
1.
In the process of horizontal well developing,especially the horizontal well with relative long hole interval,some problems as unbalanced oil production in each hole interval occur,which leads to bottom water and gas cap coning and limits the oil recovery.
针对水平井,尤其是长井段水平井开发过程中出现的各井段不能均衡采油,而导致底水或气顶锥进,极大影响水平井采收率的难题,结合目前现状,较为详细地阐述了水平井平衡采油的3种工艺技术:新型控液滤砂管技术、选择性采油技术和选择性射孔技术,并对这3种技术的适用范围及国内外应用情况都做了分析。
3)  Equilibrium between mining and filling
采充平衡
4)  reserve-production balance
储采平衡
5)  balanced injection and production rate
注采平衡
1.
To maintain a balanced injection and production rate in ultra - low permeability reservoirs is very difficult even when applying a very high pressure water injection, due to the very fine pore throats, therefore the feasibility of gas injection should be considered.
超低渗油藏由于孔喉极细,即使高压注水,也难以保持注采平衡,应考虑注气的可行性。
6)  balance of preparation and winning work
采掘平衡
1.
Rational mineable periods of three coal reserves are effective indexes for controllingthe balance of preparation and winning work.

补充资料:氨合成平衡速率氨平衡合成率
分子式:
CAS号:

性质:又称氨合成平衡速率氨平衡合成率。在不同的催化反应条件下,氨合成反应达到一定程度的化学平衡时氨合成的反应率或合成率。在实际氨合成生产中,不可能达到平衡氨合成率,在工业上设计氨合成塔时,就必须着眼于它的运行能最大限度地接近平衡氨合成率。
