摘要
概述了石油磺酸盐、烷基苯磺酸盐、石油羧酸盐和木质素磺酸盐等的制备方法。阴离子型表面活性剂可用于各种表面活性剂驱中,在三次采油中应用最为普遍,其中以磺酸盐型最多。非离子表面活性剂也大量用于三次采油中,其优点是抗盐能力强,耐多价阳离子的性能好。但其在地层中的稳定性差,吸附量比阴离子表面活性剂高等缺点限制了其使用。两性表面活性剂可用于高矿化度、较高温度的油层驱油,但价格高。三次采油用表面活性剂的研究趋向主要是耐高含盐量、耐高温、吸附损失低及成本低等方面。
The most surfactants and additives used in EOR are anionic sulfonates and carboxylates.The manufancturing methods of petroleum sulfonates,petoleum carboxylates,alkylbenzene sulfomates and ligin sulfonates were summarized.Anionic surfactants are widely used in EOR,in which sulfonate surfactants is the most type.Nonionic surfactants can also be used in EOR,which have the virtues of high anti-salt ability and anti-multivalent ions property.But the shortcomings of poor stability in stratum and higher adsorption...
