在火烧油层实验中,我们用到的燃烧管长度是1 m,内径是0.0381 m。这次研究的目的是来研究压力和空气流动率对温度,油藏,前缘速率,氧气利用率和产气量的影响。我们可以发现,随着压力的增高。(1)当压力小于6 384.5 kPa时,燃烧前缘平均温度和速度都增加。(2)采收率降低(3)氧气利用率减小,但是,当压力高于6 384.5 kPa,燃烧前缘平均温度和速度都减小。另一方面,当空气流动率从5.73×10-5m3/s增加到7.6×10-5m3/s时候,所有参数都增加。
In the experiment of burning oil layer, we use the combustion tube length is 1 m, the inner diameter is 0.0381 m. The purpose of this study was to study the effects of pressure and air flow rates on temperature, reservoir, leading edge rate, oxygen utilization, and gas production. We can find that as the pressure increases. (1) When the pressure is less than 6 384.5 kPa, the average temperature and velocity of combustion front increases. (2) Lower recovery rate (3) Oxygen utilization rate decreases, however, when the pressure is higher than 6 384.5 kPa, the average temperature and velocity of combustion front decreases. On the other hand, when the air flow rate increased from 5.73 × 10-5m3 / s to 7.6 × 10-5m3 / s, all the parameters increased.
