    • The invention is a method of recovering hydrocarbons with a surfactant flooding system, wherein the surfactant slug comprises about 0.1% to about 10% by weight of an alkylphenol lignin surfactant. The alkylphenol lignin surfactant is produced by reacting an alkylphenol having about 6 to about 15 carbon atoms in the alkyl chain with formaldehyde in basic solution at a temperature of about 50.degree. to about 120.degree. C. for about 15 minutes to about 3 hours to form a first reaction product. The first reaction product is then reacted with a kraft lignin in solution at a temperature of about 100.degree. to about 160.degree. C. for about 30 minutes to about 5 hours to form an alkylphenol lignin reaction product. Finally, the alkylphenol lignin reaction product is made more water soluble by subjecting the alkylphenol lignin reaction product to a reaction selected from the group consisting of sulfonation, sulfation, alkoxysulfonation, alkoxysulfation, and alkoxylation to produce the alkylphenol lignin surfactant.
    • 本发明是用表面活性剂淹没系统回收烃的方法,其中表面活性剂团块包含约0.1%至约10%重量的烷基酚木质素表面活性剂。 烷基酚木质素表面活性剂通过在烷基链中具有约6至约15个碳原子的烷基酚与碱性溶液中的甲醛在约50至约120℃的温度下反应约15分钟至约3小时来形成 第一反应产物。 然后将第一反应产物与硫酸铵木质素在溶液中在约100至约160℃的温度下反应约30分钟至约5小时以形成烷基酚木质素反应产物。 最后,烷基酚木质素反应产物通过使烷基酚木素反应产物进行选自磺化,硫酸化,烷氧基磺化,烷氧基硫酸化和烷氧基化的反应来制备烷基酚木质素表面活性剂而使水溶性更高。

    • The invention is a method of recovering hydrocarbons from an underground hydrocarbon formation penetrated by at least one injection well and at least one production well, which employs the steps of injecting a lignin amine surfactant slug, injecting an aqueous buffer slug of low salinity containing a polyacrylamide, injecting a high salinity aqueous drive fluid with polysaccharide, and recovering hydrocarbons and other fluids from the formation through a production well. The lignin amine surfactant slug is comprised of lignin, a primary amine having about 8 to about 18 carbon atoms and a sulfonate surfactant having an equivalent weight between about 200 and about 400 in the relative concentrations of about 1% to about 20% by weight of amine, about 10% to about 80% by weight of lignin, and about 10% to about 75% by weight of sulfonate surfactant.
