阳离子型双子表面活性剂在制备耐高温、高矿化度泡排剂中的应用
Application of gmini surfactant in preparing foaming drainage agent with resistance to high temperature and high salinity
摘要
Abstract
In normal foaming drainage work, foaming drainage agent is usually used in stratum under 90℃ with salinity less than 100 000 mg/L, hence hindering the application of foaming drainage gas recovery technology in high temperature and high salinity water-producing gas wells. In view of high temperature and high salinity in water-producing gas wells and by profoundly studying the theory of surfactant, a kind of foaming drainage agent GWJ was developed by compounding anionic surfactant and cationic surfactant which has good foaming performance, foam stabilizing property and high liquid-carrying velocity under high temperature and high salinity. Study shows that, at a temperature of 160 ℃ and a salinity of 250 000 mg/L, its initial foaming volume and foam half-life period are 1 860 mL and 620 s respectively, proving that GWJ has good high temperature and high salinity resistance properties and can meet the requirement of foaming drainage work in water-producing gas wells of high temperature and high salinity.关键词
