网络释义
1)back pressure,回压
2)back-pressure,回压
3)Hydraulic circuit,液压回路
4)counter-press backwater,背压回水
5)reducing pressure actual mining,降压回采
6)pressure regain,压力回收
用法和例句
The conventional seepage flow experimental equipment was reformed by additional back-pressure controlling system in the end of core holder.
本实验在常规渗流实验岩心夹持器末端增加了一套回压控制装置,渗流实验过程中,通过给岩心施加不同的回压,模拟了储层在变压条件下的流体渗流情况。
To figure out these curves in a time-saving way,this paper derived equations to calculate relative permeability of water displacing gas by experimental data,and also designed a set of back-pressure equipment to measure relative permeability of water displacing gas under unsteady-state conditions.
为此,根据地下水动力学原理推导了利用实验测定数据计算水驱气相对渗透率的公式,并设计了一套回压装置进行非稳态水驱气相对渗透率测这的新方法,用某气藏的真实岩心在该装置上进行水驱气相渗透率曲线的测定,其结果和用稳定法测定的结果比较吻合,证明了所建立的非稳定法测试装置和计算公式是可行的,突破了水驱气相对渗透率曲线只能用稳定法的传统方法,使气水相对渗透率的测定具有快速、准确的特点。
