中国政府正在寻求二氧化碳气体减排措施。 CO2捕集和地质封存是主要措施之一。将CO2注入油藏不仅可以达到CO2地质封存的环保目的，而且可以提高石油采收率，实现经济效益，有助于抵消CO2封存的成本。因此，油藏是CO2封存的最佳场所之一。对于水驱后CO2驱油藏，评价CO2提高采收率和封存能力潜力的方法有两种，即质量平衡法和类比法。通过将这两种方法结合起来，本文提出了一种新的方法，可以合理地用来评估这些潜力。此外，还提出了准噶尔盆地CO2封存和提高采收率的筛选标准。根据CO2源匹配、储层特征、流体特征等指导原则...
The Chinese government is seeking CO2 gas emission reduction measures. CO2 capture and geological sequestration is one of the main measures. Injecting CO2 into oil reservoirs can not only achieve the environmental protection purpose of CO2 geological sequestration but also improve oil recovery and realize economic benefits, which helps to offset the cost of CO2 sequestration. Therefore, the oil reservoir is one of the best sites for CO2 sequestration. As for the reservoir of CO2 flooding after water flooding, there are two methods for evaluating the potential of CO2 enhanced oil recovery (EOR) and sequestration capacity, which are the mass balance method and analogy method. Through a combination of these two methods, this paper presents a new method, which can be reasonably used to evaluate these potentials. Besides, the screening criteria of CO2 sequestration and EOR in the Junggar Basin are also proposed. On the basis of the guidelines of CO2 source matching, reservoir characteristics, and fluid charact...
