Withdepleting ofthe conventional oil and gas resources,China's major oil fields haveentered the second, third recovery periods.Heavyoilasa kind of unconventional oil resource has great exploitation value. In-situ combustion technology is an important method for heavy oil recovery,thus development of thein-situ combustion can contribute to the recovery of the heavy oil resources.In thispaper, basedonresearch and experimental literatures of thein-situcombustiontechnology,domestic and foreignin-situcombustion technologies were summarized,the laboratory test and field application ofthein-situcombustion technologywereintroduced. It’spointed out thatthe developmentdirectionofin-situ-combustiontechnologyshould bethestudy onitsreaction principle and field operation plan.%随着常规油气资源开采的枯竭，我国各大油田已经进入了二次，三次采油时期。稠油作为一种非常规石油资源具有极大的开采价值。火烧油层技术是稠油开采的重要手段，因此对火烧技术的研究有助于稠油资源的开发。文章在调研国内外火烧油层研究与试验文献的基础上，对国内外火烧油层技术进行了全面的总结和概括，介绍了火烧技术的室内试验与现场应用，提出下一步火驱发展的方向为反应原理的研究与现场操作的实施规划。
