摘要
One of the major problems of heavy oil thermal recovery is the inadequacy of understanding the multi-field coupling displacement mechanisms to improve the oil production and extraction ratio. From the perspective of "force" and "flow" in thermodynamics, oil displacement fields are divided into three groups: destination, driving and resistance potential fields. Based on the seepage law, the compositional structure of driving and resistance potential fields has been established by making use of non-equilibrium thermodynamics. In addition, coupling indexes among driving, resistance and a combination of both potential fields can be deduced. Then, the main process of multi-level analysis of oil displacement mechanism of field synergy in the process of heavy oil thermal recovery can be put forward. A practical multi-level case study of typical hot-water flooding displacement can provide useful information and guidance to enhance the displacement process.
