Kenli Oilfield,as a complicated fault-block oilfield with a large proportion of small bounded fault blocks with medium-low permeability,is short of stratum energy,and the oil production rate is lower,so it is one of the important subjects of oilfield development how to enhance oil recovery of the low-permeability fault block reservoirs. In which edge water and bottom water is not full of activity. The paper mainly presents the mechanism and the character of carbon dioxide huff and puff,and analyzes the effect of the application in Kenli Oilfield.It is proved that the technique reveals wide application prospect for developing reservoirs with medium-low permeability.
