| 摘要: |
| 泡沫驱是目前油田广泛使用的一种提高采收率技术,泡沫流体由于其独特的性质,对于驱替过程中窜流的防治以及油田开发增效具有重要意义。详细介绍和评述室内泡沫稳定性研究和流动机制模型,总结和分析矿场泡沫注入方式以及泡沫驱在油田中的综合应用。结果表明:泡沫稳定性影响泡沫驱的性能,纳米颗粒等合适的添加剂有助于增强泡沫的稳定性;现有泡沫流动模型虽较为成熟,但部分参数仍以经验替代为主,缺少定量化的表征以及现场应用的结合;泡沫的矿场注入方式多样,应根据不同的生产需求选择不同的注入方式;国内油田在实施泡沫驱过程中,寻找廉价气源是解决开发经济性问题的关键,复合强化泡沫驱是未来的主要研究发展方向。 |

| Abstract: |
| Foam flooding is an efficient and widely applied enhanced oil recovery technology in oilfields. Foam fluid is of great significance for the prevention of cross flow during gas and water flooding due to its unique properties, which can significantly increase oil production. The indoor foam stability study and foam flow models were reviewed and described in details along with the foam formation and injection modes and its comprehensive application in oilfields. The stability of foams is of great importance for the performance of foam flooding, and suitable additives such as nanoparticles can be used to enhance the foam stability. The existing foam flow models are relatively mature, but many model parameters are slack of quantitative characterization and combination of field applications. The formation and injection of foams in oilfield are important for their performance in field operation, and different injection methods can be selected and optimized based on different production requirements. In the process of implementing foam flooding in domestic oilfields, finding economic gas sources is the key issue to reduce the operation cost. Composite and enhanced foam flooding is the main research and development targets in the future. |
