湿式燃烧的实验研究

Experimental study on wet combustion

利用火烧油层燃烧管物理模拟技术 ,对胜利油区河口油田稠油进行了湿式燃烧实验。研究了湿式燃烧条件下的燃料消耗量、视氢碳原子比、燃烧前缘推进速度和空气需要量等参数 ,以及注水量与注空气的比值对火烧油层性能的影响。结果表明 ,湿式燃烧较干式燃烧可以更有效地回收已燃区的热量 ,并大大降低燃料消耗与空气需要量 ,提高了采收率。通过湿式燃烧的实验研究 ,为火烧油层在现场进行湿式燃烧实验提供了设计参数。

Incorporating physical simulation on pipe for formation combustion, heavy oil formation of Hekou oilfield, Shengli oil province has undergone wet combustion test. Many parameters have been achieved, such as fuel consumption, apparent atomic ratio of hydrogen to oxygen, fire front advance speed, air consumption, etc. the influence arising from the ratio of water injected to air injected upon combustion performance are also studied. In general, wet combustion is more effective than dry one since heat produced will be recycled more effectively to reduce fuel and air consumption, while recovery will still increase. Design parameters for putting formation wet combustion into site operation are also presented through experimental research.
