1) retrograde time
返转时机
1.
2PV in most wells,and the retrograde time is earlier than that of mid-permeability reservoirs,and high-permeability reservoirs remain highest injectivity during the whole polymer flooding,which is unfavorable for improving the development results.
2PV时吸水剖面发生返转,低渗透层吸水剖面返转时机先于中渗透层,且在整个聚驱过程中高渗透层仍保持最高的吸水量,对改善油层开发效果不利。
2) turnover
返转
1.
The results show that the E2γ ray energies are fitted in high quality,and the phenomena of the turnover in dynamical moment of inertia can be also reproduced well.
对A～ 1 90 ,1 50区超形变转动带的分析结果表明 ,超形变带能谱公式不仅可以相当精确地描述γ跃迁能谱 ,而且可以复现动力学转动惯量的“返转”(turnover)现
3) retrograde period
返转周期
4) profile reversal
剖面返转
1.
Types and changing laws of profile reversal during polymer flooding;
聚合物驱剖面返转类型及变化规律
5) changing laws of profile reversal
返转规律
6) type of profile reversal
