空气泡沫驱油技术综合了空气驱油和泡沫驱油的双重优势,用泡沫剂作为调剖剂、空气作为驱油剂,克服了空气驱“气窜”的缺点,成本低、安全可靠。而且具有传统的低温氧化和流度控制作用,尤其适用于高含水、非均质严重、存在微裂缝的油藏。因此,注空气泡沫开采技术在我国的应用前景十分广阔,特别是可以进一步解决特低渗、低渗透油藏开采所面临的开发难题。
Air foam flooding technology combines the dual advantages of air displacement and foam flooding. Using foam as a profile control agent and air as an oil displacement agent overcomes the shortcomings of air displacement and low cost. It is safe and reliable . But also has the traditional role of low temperature oxidation and flow control. It is especially suitable for reservoirs with high water content, serious heterogeneity and microcracks. Therefore, the injection of air foam mining technology in our country is very broad prospects for the application, in particular, can further solve the ultra-low permeability, low permeability reservoir development problems facing the development.
