Thermodynamic Modelling of Water/Hydrocarbon Mixtures for Thermal Oil Recovery Simulation

在蒸汽注入模拟中，组分建模对于描述原油采收率机理是非常重要的。 流体流动，热，和相行为之间的相互作用的详细调查，需要相行为进行建模，通过使用一个立方状态方程（EOS）。 拟议的研究解决了两个技术问题，需要解决的可靠的蒸汽注入成分建模。 一个是水/烃混合物的立方状态方程的定量表示。 另一种是可用于流动模拟的鲁棒高效的等焓闪光。 两名博士生将在拟议的三年期项目中开展这两个子项目。

Compositional modelling is important to represent oil recovery mechanisms in steam injection simulation. Detailed investigation of the interaction among fluid flow, heat, and phase behaviour requires that phase behaviour be modeled by use of a cubic equation of state (EOS). The proposed research addresses two technical issues that need to be solved for reliable compositional modelling of steam injection. One is quantitative representation of water/hydrocarbon mixtures with a cubic EOS. The other is robust and efficient isenthalpic flash that can be used in flow simulation. Two PhD students will conduct these two subprojects in the proposed three-year project.
