摘　　要：国内外都开展过轻质油藏注空气采油现场试验,但应用条件差别较大。分析了美国及中国轻质油藏注空气驱应用现状。其中,美国以高压注空气进行二次采油为主,油藏温度高、埋深大、油质轻,利于低温氧化及混相;我国以空气/泡沫调驱或空气-水交替注入为主,主要用于低渗透轻质油藏稳油控水,虽然油藏温度及埋深普遍较低,产出气中氧含量均低于5%,确保了注空气采油过程中的安全。受油藏条件及气源影响,未来我国空气/泡沫驱将发挥重要作用。Air flooding in light oil reservoirs has been carried out home and abroad, with dif- ferent application conditions. The details of field application of air flooding in US and China were analyzed in this paper. It can be concluded that HPAI is the main form used in light oil reservoirs of US, with high reservoir temperature, high oil layers depth and light oil, all of which facilitate LTO and miscible drive. For China, air flooding is mainly used for stabilizing oil production and controlling water cut in low permeability light oil reservoirs, with the form of air foam flooding or WAG. Though reservoir temperature and oil layers depth are commonly low, the oxygen content in yielded gas was lower than 5 %, which assured the safety of air drive process. Considering the reservoir condition and gas source, it is suggested that air foam flooding will play an important role.
