中文摘要：
油藏多孔介质内注蒸汽驱油过程存在能量和火用的传递和转换．以油藏多孔介质内注蒸汽驱油过程的火用方程为前提，结合基本广延量的平衡方程，建立驱油过程的能量传递方程，过渡到火用传递的动力学方程，通过热火用、压火用传递的分量方程得到注蒸汽驱油过程的总火用传递方程．并应用CMG软件对注蒸汽驱油过程进行数值模拟，探讨了注蒸汽驱油过程热火用和压火用之间的转换和传递规律及火用损机制，为驱油过程能量系统优化提供理论依据．
英文摘要：
Energy and exergy transfer and conversion exist in the process of steam flooding in oil reservoir porous media, on the premise of exergy equation in the process of steam flooding in Oil reservoir porous media, combined with the balance equation of basic extensive parameter, the energy transfer equation in the oil displacement pr（~cess can be established, which can be transited to the dynamic equations of exergy transfer. Transfer equation of total exergy in the process of steam flooding can be obtained through the component equations for thermal and pressure exergy transfer. Then the CMG software is applied-to carry out the numerical simulation of the process of steam flooding. The principle of transfer and conversion between thermal and pressure forms of exergy and the exergy loss mechanism are discussed, which provides theoretical foundation for optimizing the energy system in oil displacement process.
