摘　　要：针对蒸汽驱采油对高干度的要求,通过对油田专用常规直流式注汽锅炉产汽干度低的原因分析和对策研究,在常规直流式注汽锅炉制汽结构原理的基础上,增设了过热段、汽水分离器和汽水混合器,在通常水质条件下,将注汽干度提高到100%及微过热。达到了稠油汽驱采油对蒸汽干度的要求,提高了稠油开采的采收率。The steam quality is a major factor during the steam drive process. The reasons of the lower steam quality for the conventional once-through steam boiler in the oilfield were analyzed and discussed. The superheat, the steam separator and the fizzy mixer were added and designed in the former and conventional producing steam structure. And then, the efficiency of heavy oil recovery increased when the steam quality increased to 100% or more under the normal water quality, and the new process reached the requirement of steam quality during the steam drive process.
