Abstract
Study on multi-phase and multi-component seepage mechanism for mixing flue gas assisting steam huff and puff is of great significance for understanding the change of seepage physical field different to conventional steam huff and puff and improving the thermal recovery results. In this paper, multi-phase and multi-component anisotherrnal numerical model is built for reservoir numerical simulation, in order to systematically study the phase change rule of flue gas, steam and crude as well as the variable phase seepage characteristics of multi-component system. The results show that, mixing flue gas injection can increase the steam quality in oil layer effectively. The dissolution and expansion of flue gas significantly extend the crude viscosity reduction range. Meanwhile, C02 dissolution in flue gas can decrease oil-water interfacial tension effectively and increase the microscopic displacement efficiency.关键词
