空气、泡沫驱提高特低渗透油田采收率效果分析

Effect Analysis of Enhancing Ultra-low Permeability Oilfield Recovery by Air-foam Flooding

甘谷驿油田唐80井区为特低渗透、低产、低饱和轻质油藏,油藏埋藏浅,地层温度低,在2007年9月份开始试注空气、泡沫,目前试验井组丛54.丛55增产较为显著,油井含水率明显降低,为特低渗透油田提高采收率探索了新的途径。

Tang 80 wells district of Ganguyi Oilfield is ultra - low permeability, low - yielding, low in saturated light reservoir, shallow reservoir buried, formation of low temperature. In September 2007, it began to test air - foam flooding, the current test well group 54 and well group 55 yield more significant, in oil wells of water cut decreased significantly, it explored a new way to enhanced oil recovery for the ultra- low permeability oilfield.
