摘　　要：新疆稠油主体开发区已进入蒸汽开发后期,需要转换开发方式,进一步提高采收率,筛选A油藏开展火驱开发技术评价研究。火驱能否保持高温燃烧将会影响油藏开发效果,因此评价火驱燃烧状态显得十分重要。通过化验及进行监测资料分析建立了一套火驱燃烧状态评价方法,结果表明试验区高温燃烧特征明显,这也是国内首次在注蒸汽开发后期稠油油藏开展火驱试验实现高温燃烧。The main oil development zones of Xinjiang heavy oil reservoirs were at the late stage of steam injection,and it was needed to change the development modes for further enhancing oil recovery and choosing Reservoir A for evaluating in-situ combustion of heacy-oil reservoirs.In-situ combustion would affect the reservoir development effect whether it could maintain high temperature combustion,therefore the evaluation of in-situ combustion status was very important.In this paper,by analysis of testing and monitoring data,a set of data state in-situ combustion evaluation methods are established,and the results show that high temperature combustion characteristics are obvious in the experimental zones,then this is the first time to achieve in high temperature combustion in heavy oil reservoirs at the late stage of heavy oil reservoir development.
