摘　　要：针对常规单一表面活性剂存在的不足，研究了高活性FHB-10复合表面活性剂的化学组成与使用性能。其中FHB-10复合表面活性剂配方体系主要由非离子离子型表面活性齐1、增效剂、多元有机醇复合溶剂等组成，其在0.25％的浓度下表面张力〈23．2mN／m、界面张力〈1．3mN／m；在离子浓度10×10^4mg／L的高矿化度地层水中或120℃以下的温度条件下对液体的表面活性影响幅度较小，与压裂液、常规酸化液配伍性好。经室内试验表明：通过非离子表面活性剂与离子型表面活性剂的复配效应以及多元化学添加剂的辅助作用，有效地提高了产品在水基液体中的表面活性，并大幅度地降低了材料成本，弥补了单一表面活性剂在成本和使用性能方面存在的缺陷。Aimed at the shortcoming of single surfactant,the composition and performance of high active composite surfactant FHB-10 were studied.The FHB-10 was composed of non-ionic and ionic surfactants,synergistic agent,and organic polyalcohol composite solvent etc.The performance was surface tension<23.2mN/m and interfacial tension<1.3 mN/m in the concentration of 0.25%;the surfactivity was less influence on high extent of mineralization formation water that ion concentration reached to 10×104mg/L or in context which the temperature was below 120℃;the compatible ability was good with fracturing fluid and conventional acidizing fluid.Its surfactivity is enhanced effectively in water base fluid.The cost of raw material is greatly reduced and the shortcomings of single surfactant in the composition and performance are avoided.
