Evaluation of the performance of polymer gels mixed with asphalt particle as a novel composite profile control system
E-mail:
This paper presents gels with asphalt particle (GAP) as a novel composite profile control system, which has better sealing effect for plugging channeling in fractured reservoir. This composite agent was prepared by modified asphalt particle and polymer gels served as suspension. Laboratory core-flood tests showed good injectiviy of GAP solution in high permeability zone with a high plugging rate. Also, the enhance oil recovery mechanism of GAP and polymer gels in fractured reservoir were compared by parallel core-flood test. Simulation results indicate longer response time and better enhance oil recovery for GAP than polymer gels in fractured system.
