摘　　要：针对进入开发中后期的小洼油田特稠油油藏存在的问题,在总结氮气助排成功应用和借鉴其他油田注空气采油试验的基础上,通过工艺技术优化,开展了2井次注空气辅助蒸汽吞吐先导试验,结果表明,洼10^(-3)井注空气后,注气压力提高了4.5 MPa,注汽生产周期延长了1.5倍,为稠油油藏中后期提高采收率开发提供了技术支持。In view of the problems concerning the extra-viscous crude oil reservoir in Xiaowa Oilfield that is in its middle and late development period,a pilot test of air-assisted steam stimulation was carried out for2 well-times by summarizing the successful application of nitrogen-assisted steam stimulation technology,by making reference to the air-assisted steam stimulation tests carried out at other oilfields and by optimizing technologies. According to the results of test,the air injection pressure was increased by 4. 5 MPa and the air injection production cycle was extended by 1. 5 times after air was injected to Well Wa 10（-3）,which has provided the technical support for enhancing the oil recovery efficiency in the middle and later period of this extra-viscous crude oil reservoir.
