The Screening of Oil Resistant Foaming Agents and Oil Displacement Effect Evaluation of Foam Flooding

Abstract:

The poor oil resistance of traditional foam system leads to gas channeling and low oil recovery in the process of foam flooding field trial. Aiming at this phenomenon, a new oil resistant and low tension foam system is proposed. Firstly, dodecyl hydroxypropyl phosphate betaine and fluorocarbon 101005 were selected as oil resistant foaming agents from several high performance foaming agents. Then, mixed the two agents with low tension betaine in certain proportions to form oil resistant and low tension foam system and compared oil displacement effect with single foam system, traditional foam system and single low tension system. Experimental results show that, foam performance of oil resistant and low tension foam system is the best in the presence of oil, and the foam flooding recovery reaches to 16.10%, which is much higher than that of single foam system, traditional foam system and single low tension system.
