annulus test

基本解释

In the paper we generalize and analyze some practical test data of a oilfield to get PVT experience law of annulus liquid.
通过油田区块实际测试资料得到有关环空液柱流体的PVT经验规律，然后应用该规律确定相应参数，折算出抽油井井底压力；
The test section was a vertical tube-in-tube heat exchanger with hot water in the annulus and the test refrigerant in the inner tube.
试验换热管为垂直套管式，外层为加热水路，内层为工质回路，中心布置着电极。
The experimental study on the relationship between annulus pressure differential, interlayer differential and cementing quality is carried out on the lab simulation test unit.
室内利用模拟试验装置进行了环空压差和层间压差与固井质量的关系的试验研究。
