摘　　要：海上稠油储量规模大,对于黏度大的特殊稠油使用常规冷采开发,采油速度和采收率低,经济效益差。为有效动用稠油资源,改善开发效果,海上已开始进行多元热流体吞吐和蒸汽吞吐热采试验探索。蒸汽吞吐热采后期表现出井底流压低、气窜等现象,寻找后续接替技术成为改善稠油中后期开采效果的迫切需求。通过文献分析可知,火烧油层技术较多元热流体开发可大幅度提高原油产量。为充分发挥火烧油层在海上油田实施的潜力,给海上稠油中后期开采提供技术支持,应深入开展火烧油层燃烧反应的微观机理、燃烧反应速度的表征、影响燃烧的各类因素等方面的研究。The offshore heavy oil reserves are large. For special heavy oil with large viscosity, conventional cold recovery development has low oil recovery rate and recovery factor, and poor economic benefits. In order to effectively utilize heavy oil resources and improve development effect, multi-component thermal fluid huff and puff and steam huff and puff thermal recovery experiments have been carried out offshore. In the late stage of steam huff and puff thermal recovery, the phenomenon of low bottom hole flow pressure and gas channeling appears. It is urgent to find a follow-up replacement technology to improve the recovery effect of heavy oil in the middle and late stages.Through literature analysis, it can be seen that the oil production can be greatly increased by burning oil reservoir technology compared with the development of multi-component thermal fluid. In order to give full play to the potential of burning oil layers in offshore oil fields and provide technical support for the mid to late stage development of offshore heavy oil, it is necessary to carry out in-depth research on the micro mechanism of burning oil layers,characterization of combustion reaction speed, and various factors affecting combustion.
