SURFACTANT FORMULATIONS FOR FOAM FLOODING |
摘要 |
A foam generating surfactant formulation includes a betaine, an alpha- olefin sulfonate and a nanofluid. The betaine is preferably a cocamidopropyl betaine or laurel betaine. The alpha-olefin sulfonate is preferably an anionic surfactant having between 8 and 18 carbon atoms per molecule. The nanofluid is preferably an oil-in-water nanofluid that includes an emulsifying surfactant, a solvent, a co-solvent and water. The addition of the nanofluid increases the thermal stability and salt resistance of the foam generating surfactant. |
