摘要： 过热蒸汽与普通湿蒸汽相比, 具有更高的热焓和更大的比容; 采用过热蒸汽进行吞吐开发, 不仅提高了井底的蒸汽干度、扩大了蒸汽波及体积; 而且过热蒸汽的降黏作用、热膨胀、解堵作用、原油蒸馏率、驱油效率均高于普通湿蒸汽。肯基亚克油田盐上稠油油藏采用直流注汽锅炉与蒸汽再加热装置进行了现场过热蒸汽吞吐试验, 试验获得了较好的开发效果, 对比盐上稠油油藏普通蒸汽与过热蒸汽的吞吐效果, 后者的增产效果显著。

Abstract: Superheated steam, compared with wet average steam, has higher heat content and specific volume, by which for steam stimulation, not only can the bottom hole steam quality and steam swept volume be increased, but also it is characterized by higher visbreaking, heat expansion, blocking, crude distillation rate and oil displacement efficiency than those by wet average steam. The upsalt heavy oil reservoir in Kenjiyake field has experienced pilot test of superheated steam stimulation using direct steam generator integrated with steam-reheated devices, and good responses are gained. Compared with wet average steam stimulation, the superheated steam stimulation applied to such a heavy oil reservoir development is of more perfect effect.

Key words: superheated steam, heat content, specific volume,steam quality, upsalt reservoir, efficiency
