【Abstract】 Because of abundant air supply and cheap cost,people now pay more attention to air injection technique. We have researched on the potentiality of air injection LTO in oil fields in China. The result indicates that the using of air injection is a promising way in China. We can exploit low-permeability reservoir and enhance oil recovery of polymer flooded reservoir by using this technique. As advancing of technical progress, air injection LTO process will be an inevitable trend of gas flooding both in China and the world. Moreover, the principle and evaluation method of LTO process are discussed, and the developing trend of air injection is forecasted.更多还原
