针对目前我国注汽干度普遍较低的情况，在注汽锅炉出口加装汽液分离器，把湿蒸汽中的饱和水尽可能多地从饱和蒸汽中分离出来，从而产生干度值较高的饱和蒸汽。同时，研究了汽液分离器分离出的饱和水的热能综合利用技术。经现场应用，证明工艺流程设计合理，自动化水平适中，为提高稠油采收率开辟了新途径。 In view of the fact that the steam injection dryness in China is generally low at present, a vapor-liquid separator is installed at the outlet of the steam injection boiler to separate the saturated water in the steam as much as possible from the saturated steam to produce a higher dryness value Saturated steam. At the same time, the comprehensive utilization of thermal energy of saturated water separated by vapor-liquid separator was studied. The field application shows that the process design is reasonable and the level of automation is moderate, thus opening up new avenues for increasing heavy oil recovery.
