... Abstract Conventional water flooding method becomes ineffective facing low and ultra-low permeability oilfields, and the recovery rate of the non water harvesting period is only about 20%. Most residual oil is trapped in the reservoir and cannot be recovered. The conversion of injection well...

...% and 16.1% OOIP recovery even if the recovery after polymer flooding was more than 50%, respectively. The obvious increasing in injection pressure during the foam flooding indicated that foam fluid had stronger profile control ability than polymer. The distribution of residual oil in three-layer cores...
