摘要
低渗透轻质油藏注空气低温氧化技术越来越受到广大学者的重视,轻质原油在低温氧化过程中会发生化学反应,组份组成变化,而以前的油气两相相平衡计算模型不能用于描述具有化学反应的油气相态变化过程,为解决这难题,在传统相平衡计算模型的基础上建立了实用于研究轻质原油低温氧化相态变化的相平衡计算模型,为研究原油低温氧化相态变化过程提供理论支持,对促进注空气低温氧化驱替技术进步有一定指导意义。
The technology of low temperature oxidation by Air Injection in the Low permeability reservoir gets more and more attention. The chemical reaction will happen during the low temperature oxidation process. The composition of component will change during the low temperature oxidation process too. But the previous two phase of oil and gas equilibrium calculation model cannot be used to describe the process of the oil and gas phase transition which have chemical reaction. In the paper, on the basis of the traditional phase equilibrium calculation model, a new phase equilibrium calculation mode is established which can be use to describe the change of the phase during the process of the low temperature oxidation. It can provided theory support for researching the process of the low temperature oxidation, and has certain significances to promote the flooding of the technology of low temperature oxidation by Air Injection in the Low permeability reservoir.
