摘要
我国剩余石油储量中大部分为高温高盐、低渗透、稠油等难以开采的苛刻油藏。传统石油磺酸盐、烷基苯磺酸盐等表面活性剂由于活性低、耐盐性差而导致低效甚至无效。本文综述了驱油用新型表面活性剂,如阴-非离子表面活性剂,甜菜碱表面活性剂、阴阳离子混合表面活性剂研究进展及发展方向。
More and more reservoirs found recently have harsh conditions,such as high temperature,high salinity and low permeability as well as high viscosity.The common surfactants such as petroleum sulfonate and alkylbenzene sulfonate can’t meet the requirements for chemical enhanced oil recovery.Recent advances in novel surfactants EOR,such as alkoxy carboxylate/sulphonate/sulfate surfactants,amphoteric surfactants,mixtures of anionic/cationic surfactants are introduced.
