Experimental study and field application of surfactant-polymer flooding in offshore oilfield

Restricted by the short life of the oil development platform and its high investment, offshore oilfield needs higher oil recovery rate in the early developmental stage so as to recover its investment fast. Therefore, polymer flooding method carried out in medium water cut period was proposed. The production performance improved through the use of polymer flooding in Bohai H oilfield, but became worse when the polymer...
