摘　　要：高温、高压、高矿化度的严重非均质油藏注水开发形成优势渗流通道后,注入水短路循环,油田处于低产出、特高含水状态,聚合物驱等三次采油技术难以有效发挥作用。空气泡沫在地层中具有较高的视黏度,可以有效封堵优势渗流通道,扩大水驱体积。通过室内实验和现场实施表明,对处在特高含水开发期的严重非均质油藏,空气泡沫调驱是一种有效降低含水、提高采收率的新方法。After forming of preponderant percolating channel during waterflooding in serious heterogeneous oil reservoir with high temperature, high pressure and high salinity, the injected water is in short circulation state and the oilfield will be in low production and extra-high watercut state. At this time, the tertiary oil recovery technology by polymer flooding is difficult to play an effective role. The air foam has high apparent viscosity in formation, which can effectively plug the preponderant percolating channel and enlarge the waterflooding volume. Laboratory test and field application show that the air foam flooding is a new method to effectively reduce watercut and enhance oil recovery for the serious heterogeneous oil reservoir at high watercut development period.
