Discrimination of Reservoir Driving Mode Based on Exergy Transfer Theory

Thermodynamic essence of reservoir driving process is studied, which is a typical exergy transfer problem that uses multi-potential fields as driving source to achieve the purpose of oil displacement. The discrimination of reservoir driving mode is derived on the basis of the establishment of driving potential field exergy transfer, which includes driving work (exergy), driving power (exergy flow density), the driving work rate and the driving power rate. Finally with the two-dimensional axial symmetry of hot water flooding process as an example, the main driving mode is distinguished.
