摘要
以大庆榆树林油田扶杨油层为例,利用高温高压微观实验系统,分别在静态和动态条件下应用微观网络模拟技术观察了原油与CO2间的流动现象。通过实验现象,分析了CO2非混相驱驱油机理,并确定了CO2与大庆榆树林原油的拟混相压力。
Taking Fuyang oil reservoir in Yushulin of Daqing oilfield for example,the authors use high-temperature high-pressure microscopic experimental system and micro-network simulating technology to observe the fluid flow between reservoir oil and carbon dioxide respectively under static and dynamic condition;through analyzing the experiment phenomena,the paper investigates the mechanism of immiscible CO_2 injection and determined the pseudo miscibility pressure of CO_2 and Yushulin oil.
