Abstract

Broad distribution relative molecular weight HPAM (“B-HPAM” for short) was produced by mixing with three kinds of<br>different HPAM at different weight ratios, whose viscosity-average molecular weight were 19×106, 25×106, 35×106,<br>respectively. During the chemical flooding stage, the small flow resistance in high permeability formation led the HPAM<br>solution to flow through easily. Firstly the larger polymer clews absorbed in the larger pore throat and then the smaller clews<br>absorbed in the smaller pore throat. Enlarged the swept volume and enhanced oil recovery. Therefore, it was a promising<br>profile control method.
