新疆油田超稠油开发和普通稠油后期开采需要更高的蒸汽干度，而常规锅炉蒸汽出口干度只有80%，已不能满足现阶段注蒸汽开采工艺要求。为此，提出了汽水分离、过热、掺混方法进提高蒸汽干度，并使其伴有15℃过热度，达到了蒸汽驱稠油热采条件，现场应用表明该方法在节能、环保和能效上效果显著。
新疆油田超稠油開髮和普通稠油後期開採需要更高的蒸汽榦度，而常規鍋爐蒸汽齣口榦度隻有80%，已不能滿足現階段註蒸汽開採工藝要求。為此，提齣瞭汽水分離、過熱、摻混方法進提高蒸汽榦度，併使其伴有15℃過熱度，達到瞭蒸汽驅稠油熱採條件，現場應用錶明該方法在節能、環保和能效上效果顯著。

Ultra heavy oil development and ordinary heavy oil late-stage development require higher steam dryness in Xinjiang oilfield. Conventional boiler steam outlet dryness is only 80%, which cannot meet the requirements of the present stage steam injection process. So steam-water separation and overheating and blending method has been used to improve the steam dryness. The treated steam accompanied by 15 ℃ superheat can meet the requirements of the heavy oil thermal recovery. Field application shows that the method is energy conservation and environmental protection, and its energy efficiency is significant.
