在总结以往经验、吸收国内外最新技术基础上，确定了以电热器点火、电缆从油管内起下及油、套环空注气为主要特点的火烧油层先导试验项目。并建立了数学模型及物理模型。该技术研究成功后，在三种类型油藏的４口井上做了火烧油层先导试验，点火成功率１００％，除第一口井因缺乏经验，燃烧期发生严重气窜外，其余３口井都基本按设计完成了点火、燃烧及采油生产全过程，共增油２１２１．８ｔ，效果显著。
On the basis of summing up the past experiences and absorbing the latest technologies both at home and abroad, the pilot project of the burning oil layer with the main feature of ignition of the electric heater, cable starting from the oil pipe, and air injection through the annulus was identified. And established a mathematical model and physical model. After the success of this technology research, the pilot test of the pyrophoric oil layer was made on 4 wells of 3 types of reservoirs with a success rate of 100%. Except for the first well due to lack of experience and serious gas channeling during the combustion period, the remaining 3 wells According to the design are basically completed the ignition, combustion and oil production process, a total of 2121.8t oil, the effect is significant.
