摘　　要：稠油注空气低温催化氧化采油技术是集热采、N2驱、表面活性剂驱及稠油井下改质技术于一体的稠油开采新技术,该技术成本低廉,可促进稠油改质和有效提高原油采收率。研究分析了该技术的原油及油藏的适应性。结果表明,该技术对于普通稠油、特稠油、超稠油及海上稠油样均具有较好的低温催化氧化性能,可应用于注蒸汽热采后的稠油老区、海上及难动用稠油油藏。该技术在辽河油田的现场试验也取得了较好的效果。Air-injection low-temperature catalytic oxidation is an emerging heavy oil recovery technology which integrates thermal recovery,N2 flooding,surfactant flooding and down-hole upgrading. This cost-effective technology can accelerate heavy oil upgrading and effectively enhance oil recovery. Its adaptability to crude oil and reservoirs were analyzed. The results indicate that this technology can achieve efficient low-temperature catalytic oxidation of heavy oil,extra-heavy oil,super-heavy oil and offshore crude oil samples. It can be applied to mature fields that have been developed through steam injection thermal recovery and offshore heavy oil reservoirs that are difficult to produce. The air-injection low-temperature catalytic oxidation is successfully applied in Liaohe oilfield.
