Laboratory Test of Wet In-situ Combustion

After the laboratory test of wet in situ combustion was compared with that of dry in situ combustion, it was found that the front burning speed of wet combustion is more than that of dry combustion even if the ratio of water to air is small, and that it will increase with the increase of the ratio. The optimal waterflood time of wet combustion was gained by optimization. It was also found that, compared with dry combustion, forward wet combustion can more effectively recover the heat remaining in burnt area. Therefore, it can increase the utilization ratio of the heat produced by combustion and decrease the consumption of fuel and air.
