ABSTRACT: Steam injection is a most effective way for improving heavy oil
recovery efficiency, and it has academic and practical significance for
the mechanism of multi-field synergy oil displacement. Mechanism of “diversified” oil displacement which is obtained by
traditional study methods in the exploitation territory of oil and gas fields
has both respective roles and mutual cross shortages. To describe and analyze the displacement
process of multi-field coupling with exergy transfer can simplify this kind of
problem by introducing a unified goal-driving exergy. It needs to use the method of theoretical modeling, numerical
simulation and experimental validation to study the basic
law of exergy transfer in the oil displacement process of multi-field synergy, make
a thorough research for the flooding process of steam injection with exergy transfer theory and reveal the oil
displacement mechanism in steam injection of multi-field synergy. Thus the theory instruction and technical support can be provided to improve reservoirs
producing degree and extraction ratio.
