Abstract:

The foamability of sulfate foaming agent and its stability has been evaluated by a Waring Blend Method when adding respectively four types foam stabilizers. The viscosity decrease of the four foam stabilizers solution with the increase of temperature and salinity has been investigated. And hydrophobically associating polymer and its concentration are optimized. Results show that the foam solution in which the hydrophobically associating polymer is added has stronger foamability and its foam has longer half-life. It has good applied prospects in foam flooding.

Key words: foam stabilizer, viscosity, foam, half-life, foam flooding
