摘要
The method and an apparatus for improving the steam dryness of a steam injection boiler includes injecting wet saturated steam and gas into an oil layer together in a sealed way, after the dryness of the wet saturated steam at an outlet of the steam injection boiler is improved by a dryness raiser. The dryness raiser includes a combined spray head, a steam heating chamber, a combustion chamber, and a mixing chamber. The gas generated by the combustion chamber enters into the mixing chamber and is fully mixed with the steam from the steam injection boiler. The dryness of the wet saturated steam at the outlet of the steam injection boiler can be improved to 95%-100%, and the effects of improving steam enthalpy, replenishing stratum energy and enlarging the steam wave and size are realized, so as to heat up the oil layer more effectively, and improve heavy oil development.
