Abstract:

Air injection for enhanced oil recovery has been successfully applied in various overseas reservoirs and geological settings, it has the advantages of low operation cost, high injectivity, high oil displacement efficiency and reserve tapping efficiency. In this paper, successful overseas air injection projects including light oil reservoirs, heavy oil reservoirs and bitumen reservoirs are systematically presented; current status of air injection technology in domestic reservoirs is briefly introduced; the mechanism of the technology, effect of enhanced oil recovery and the key factors of successful implementation are discussed, which can be used as a reference for the development of various domestic reservoirs.

Key words: air injection, EOR, oil displacement efficiency, reservoir, reserve tapping efficiency
