From laboratory evidences, the high oil saturation bank was formed in front of burning zone, and mainly producing pressure drop concentrated on the high saturated oil region during fire flooding.
实验证据显示，在燃烧带前缘存在高含油饱和度带，在该区域压降较其他区域集中。

The zone has the obvious features of low pressure, high saturation of condensate oil, high interfacial tension and high flowing velocity.
