摘要: 根据火烧油层室内燃烧管模拟实验台的条件,建立了一个一维数学模型.用有限差分法对该数学模型在较宽的参数范围内进行了数值计算,分析了若干重要参数对采收率、空气消耗量和燃烧前缘推进速度的影响.计算结果表明,采收率和空气消耗量对原油的相对渗透率很敏感,而绝对渗透率对其影响不大;燃烧前缘的推进速度与空气注入速率成正比,而提高空气注入速率对采收率和空气消耗量没有太大的影响.数值计算结果与实验结果吻合较好,说明所建立的数学模型和采用的数值求解方法是正确和可靠的.

Abstract: A one-dimensional mathematical model was established to describe the experimental in-situ combustion process.The model within a wide range of various parameters was solved by using finite difference method.The effects of some important parameters on oil recovery,air consumption and advancing velocity of combustion front were investigated.The numerical results show that oil recovery and air consumption are sensitive to the relative permeability of oil.The absolute permeability has only a weak effect on them.The advancing velocity of combustion front is proportional to air injection rate.The air injection rate has no significant effect on oil recovery and air consumption.The acceptable agreement between the numerical and the experimental results proves that the numerical method used to solve the mathematical model is correct and reliable.

Key words: in-situ combustion, oil recovery ratio, numerical simulation, combustion front, advancing velocity, permeability, air injection rate
