引　言在稀油油藏中溶解气驱是容易理解的 ,但在稠油和高凝油油藏中溶解气驱不是很好理解。本文介绍了描述气泡成核作用 (晶核形成 )和气泡增长过程的机械总体 -平衡模型。用适当的速率反应式推导出了瞬时 -成核作用 (ＩＮ)和累加 -成核作用 (ＰＮ)的理论。ＰＮ模型实验拟合的 Introduction It is easy to understand how to dissolve gas flooding in thin oil reservoirs, but it is not well understood that gas flooding can be dissolved in heavy oil and high pour-point reservoirs. This paper presents a mechanical total-equilibrium model describing bubble nucleation (nucleation) and bubble growth. The theory of instantaneous-nucleation (IN) and additive-nucleation (PN) was deduced using an appropriate rate response. PN model experiment fitting
