火驱开采技术作为热力采油的一个重要组成部分,它具有热驱、气驱、蒸汽驱、混相驱和非混相驱的多种驱油机理。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CO2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。
As an important part of thermal oil recovery, fire flooding technology has many oil displacement mechanisms of thermal flooding, gas flooding, steam flooding, miscible flooding and non-miscible flooding. The paper expounds the difference between fire flooding and steam injection technology based on the mechanism of fire flooding and oil displacement. From the four aspects of energy consumption, thermal efficiency, injector resource and data comparison, it analyzes the advantages of high thermal efficiency and fuel cost , Energy consumption is 50% of steam injected. Comparing CO2 emission and discharge shows that fire drive can reduce greenhouse gas emissions and play a positive role in energy conservation, emission reduction and environmental protection.
