Abstract :
The oil displacement mechanism in steam injection obtained from the indoor simulation experiments is analyzed, namely some thermal-hydraulic-mechanics-chemical coupling relation in oil reservoir porous media. The phenomenological equation for transfer process of multi-field coupling deduced from the non-equilibrium thermodynamics is simple in form and rich in connotation. The driving force of oil and gas transport deduced from fluid potential, can analyze the oil and gas displacement mechanism of multi-field coupling from the direct and indirect points.
