Precision Description and Technique of Tapping the Potential in Deep Low Permeability Reservoir of Es_3(?) in the West of Wenliu Oilfield

In consideration of the properties of high producing difference in water flooding and stray remaining oil distribution after Wenliu Oilfield going into a high water-cut stage, the distribution of remaining oil is established by using the techniques of precision reservoir description and the description of remaining oil distribution. On the basis of classification evaluation, corresponding technique for tapping the potential is used with obvious effect in consideration of the properties of remaining oil distribution.
