Title: Adaptability of gas flooding for deep reservoir with low to medium permeability in Jidong Oilfield
Abstract: Based on the research of comparison with screening criteria of tertiary oil recovery reservoir,analogy to developed blocks with enhanced oil recovery in China and abroad,analysis of gas source conditions,calculation of minimum miscibility pressure and reservoir simulation,adaptability analysis of gas flooding was conducted for deep reservoir with low to medium permeability in Jidong Oilfield.Research results show that the optimum technology is water alternating hydrocarbon gas injection.The foundation of Nanpu Oilfield provided sufficient gas sources and it is possible to reach the state of miscible phase or near miscible phase.It is efficient to enhance oil recovery and obtain considerable economic benefits after application of gas flooding technology.
