蒸汽泡沫驱油是热力开采稠油的一项重要新技术 ,国外从 50年代末开始研究 ,在理论研究和现场实验工艺方面已逐步形成了完整的体系 ,在美国最早成功地进行了一些现场试验。发泡剂是蒸汽驱油中必不可少的化学剂。将它与蒸汽或非凝结气体及盐水混合注入油层 ,可形成蒸汽泡沫。使用
Steam foam flooding is an important new technology for heat recovery of heavy oil. Since the late 1950’s, the research on steam foam flooding has been gradually carried out in the field of theoretical research and on-site experimental processes. Some field experiments were successfully carried out in the United States . Blowing agents are indispensable chemicals in steam flooding. It is mixed with steam or non-condensable gas and brine into the reservoir to form a vapor bubble. use
