CO 2注入的性能依赖于准确的CO 2最小混相压力(MMP) 和油藏条件下的混相数据。细管是测量不同混溶机制下 MMP 最可靠的工具；然而，它非常耗时和资本密集，因此无法提供高通量数据来评估其他气体的影响。气泡上升装置和界面张力消失技术更便宜且更容易运行，但这些方法无法完全捕获不同的混溶机制。在整篇论文中介绍的案例研究中，作者提出了一种高效的微流控平台，能够以更快、更轻松的方式显着测量含有各种杂质的CO 2的高质量 MMP 数据。
在高压或高温下使用现场油样和真实气体混合物进行混溶性测试需要一个能够在油藏条件下处理复杂流体系统的平台。
Performance of CO2 injection relies on accurate CO2 minimum miscibility pressure (MMP) and miscibility data at reservoir conditions. A slim tube is the most-reliable tool to measure MMP under different miscibility mechanisms; however, it is very time- and capital-intensive, making it impossible to provide high-throughput data to assess the effect of other gases. Rising-bubble apparatus and vanishing-interfacial-tension techniques are cheaper and easier to run, but these methods are unable to capture different miscibility mechanisms fully. In the case study presented in the complete paper, the authors present a highly efficient microfluidic platform to measure, in a faster and easier manner, high-quality MMP data of CO2 with various impurities significantly.
Conducting miscibility tests at high pressure or high temperature with live oil samples and real gas mixtures requires a platform capable of handling complex fluid systems at reservoir conditions.
