摘　　要：以含氟辛基磺酰氟和4,4'-二羟基二苯醚为原料,制备了氟碳双磺酸盐型CO_(2)发泡剂。考察了发泡剂质量分数、发泡温度、压力和矿化度对体系泡沫性能的影响。结果表明,当温度和矿化度升高,体系起泡体积和半衰期均减小;压强增大,体系起泡体积和半衰期均增大。当发泡剂质量分数为0.3%时,在150℃、20 MPa和100000 mg/L矿化度下,起泡体积、半衰期和综合指数分别为667 mL、28 min和18676 mL/min。室内封堵实验表明,该发泡剂泡沫封堵效果优异,阻力因子可达32.5。Fluorocarbon bis-sulfonate type CO_(2) foaming agent is prepared from perfluorooctyl sulfonyl fluoride and 4,4'-dihydroxy diphenyl ether.The influences of the concentration of foaming agent,foaming temperature,pressure and salinity on the foaming and stabilizing properties of the system are studied.The results show that both the bubbling volume and half-life decrease with the increase of temperature and salinity,but both increase with the increase of pressure.The foaming volume,half-life and composite index of the foaming agent are 667 mL,28 min and 18,676 mL·min,respectively when the mass fraction of the foaming agent is 0.3%,the temperature is at 150℃,the pressure is 20 MPa and the salinity is 100000 mg·L^(-1),indicating good resistances against temperature and salt.The indoor evaluation shows that the foaming agent has excellent foam blocking effect,and its maximum resistance factor can reach 32.5.
