稠油火驱开采技术节能减排效果分析

火驱作为稠油热采的有效接替技术,与注蒸汽开采技术相比,具有采收率高,能耗低,CO_2排放少的优势。文章从火驱驱油机理特征阐述了火驱与注蒸汽技术的不同点,从燃料开采能耗、热效率、注入剂资源、数据对比四个方面分析火驱比注蒸汽热效率高,无燃料开采成本,能耗是注蒸汽的50%;从CO_2气体排放方式和排放量对比可知,火驱能够减少温室气体排放,为油田节能减排、环保生产起到积极作用。

Analyses of Energy-saving and Emission-reducing Effect of Heavy Oil Fire Flooding Exploitation Technique

Compared with steam injection technique,fire flooding,an effective replacement technique of heavy oil thermal recovery,has a variety of advantages,e.g.high recovery efficiency,low energy consumption,less CO_2 emissions,etc.this article expounds the differences between fire flooding and steam injection from the characteristics of fire flooding mechanism.Furthermore from the aspects of energy consumption of fuel extraction,thermal efficiency,injection agent resources and data comparison,it finds out that fire...
