Abstract
Research on dodecyl benzenesulfonic acid sodium salt(SDBS)/fluorocarbon Intechem-01 surfactant(FC-01) composite displacing agent of performance,take the rate of metal mesh oil wash and static flooding,interfacial tension,and the injected water and formation water simulation compatibility testing as the indexes,the orthogonal experiment showed that mass fraction:fluorocarbon Intechem-01 surfactant 0.05%,sodium dodecyl sulfonate 0.15%,sodium carbonate and sodium bicarbonate are both 0.25%,the dynamic of the compound system with the Dingbian oilfield injection water and simulated formation water has good compatibility.
