摘要
在求解非等温单相渗流的温度场、压力场基础上,以压(火用)为统一特征项,对电加热热驱模拟过程的驱动功、驱动功率、驱动阻力、驱油速率及其相互关系作了初步分析,揭示了热采过程非等温渗流的驱替机理:通过改变温度场、减小驱动(火用)阻力,以增强驱动效果、提高采收率。
Temperature field and pressure field of single phase non-isothermal seeping process are calculated. On the basis of that, pressure exergy is denned as uniform characteristic item to analyse drive work, drive power, drive resistance, drive velocity and their correlation for electricity heating thermal drive simulating process. The drive mechanism of thermal extraction is then indicated, i.e., temperature lessens drive exergy resistance and improve drive effect.
