含两性表面活性剂的稠油降粘剂制备及应用方法技术

一种含两性表面活性剂的稠油降粘剂制备方法，包括自阴阳体系的两性表面活性剂和含数个EO基团杂化的阴离子型磺酸盐表面活性剂，自阴阳体系的两性表面活性剂∶阴离子型磺酸盐表面活性剂＝30～100∶0～70，在常温常压条件下，在反应釜中搅拌均匀即得稠油降粘剂。所选择的阴离子型磺酸盐表面活性剂可促进自阴阳体系的两性表面活性剂形成乳化网络，还有两性表面活性剂不含有苯、萘等芳香环且耐高温、界面活性高、抗盐性能好，因此具有环保无毒、易于生物降解、高效的优点；同时加入一定量的阴离子表面活性剂即能形成乳化网络，既增加降粘效果又能减少降粘剂的投加量。

Preparation and application method of heavy oil viscosity reducer containing amphoteric surfactant

A heavy oil containing amphoteric surfactant viscosity reducer preparation method, including the amphoteric surfactant from the Yin and Yang system and containing anionic surfactant EO groups the number of hybrid, since the amphoteric surfactant system: Yin and Yang anionic sulfonate surfactant = 30 ~ 100 to 0 ~ 70, in under normal conditions, in a reaction kettle uniformly stirring to obtain the viscosity reducing agent. Anionic surfactant selected can promote the activity of amphoteric surface self agent emulsion formed network system of yin and Yang, and amphoteric surfactants do not contain benzene, naphthalene and other aromatic ring and high temperature, high interfacial activity and anti salt performance, so it is non-toxic and easy biodegradation, high efficiency advantages; anion at the same time, adding a certain amount of surfactant which can form emulsion network, can increase the viscosity reducing effect and can reduce the dosage of viscosity reducer.
