文摘

A mechanistic model for PPG/surfactant/polymer combined flooding was proposed. The interaction between PPG and surfactant was mathematically described. The newly presented model was validated with core flooding cases. Two pilots from China fields were used to verify the coupled model. The sensitivity of different parameters to the recovery factor was discussed.
