Abstract: Based on the research of fireflooding production process in the Hongqian pilot test area of Karamay oilfield, Junggar basin, the paper divides energy consumption system of fireflooding and analyzes main factors influencing energy consumption for each system. The research result shows that the energy consumption of fireflooding mainly comes from air injection system, among which energy consumption of air compressor accounts for the largest proportion. Energy consumptions of fireflooding and steamflooding are compared with each other under the same oil production conditions, and it is considered that fireflooding has obvious advantages on energy consumption, and can be an effective alternative technology for successive oilfield development when oil-steam ratio of reservoir is low and energy consumption is large during thermal recovery by steam injection. Because the water cut of the produced liquid during fireflooding is low, the treatment has obvious advantages compared with steam injection
