| 摘 要： | 为实现安全有效点火,保障火烧油层成功,深入分析研究火烧油层的点火方法. 系统分析了自燃、注入热流体、电点火器、化学点火和井下燃烧器等火烧油层点火方法及其点火原理,综合比较了各种点火方法的优缺点和适用情况. 结果表明,每种点火方法均有自身的优势和不足,选取点火方法时应综合考虑油藏条件、原油特点、现场设施和可利用的条件等因素. 自燃点火方法适用于原油反应性高、油层温度高、厚度大的油藏. 如果不能或不希望自燃,则需考虑人工点火方法.

| Abstract: | To achieve ignition safely and efficiently which can influence the success chances of a fireflood, some typical ignition methods and principles, such as spontaneous ignition, hot fluid injection, electric heaters, chemical methods and downhole burners, were analyzed in this paper. In addition, the suitable reservoir conditions, advantages and disadvantages of various methods were investigated. It turns out that every technique has its own strengths and weaknesses, and some factors including reservoir conditions, native oils, site facilities and available conditions must be considered synthetically to select the most suitable one. Spontaneous ignition is feasible for an oil-bearing stratum where temperature, thickness and reactivity of native oil are suitable. If spontaneous ignition is not desirable or fails to appear, some artificial means are implemented. |
