摘要: 以烯丙基聚乙二醇、环氧氯丙烷、含氢硅油和有机胺为主要原料,制备了6种有机硅表面活性剂ASiE-500,ASiD2-500,ASiD4-500,ASiE-700,ASiD2-700和ASiD4-700。采用红外光谱和核磁共振氢谱对其结构进行表征,对目标产物进行了表/界面性质以及CO2驱油实验的研究。实验结果表明,所制备的6种有机硅表面活性剂均具有较低的表面张力,产物ASiE-500水溶液在25 ℃下的表面张力最低可达25.3 mN/m;随NaCl和MgCl2质量分数的增大,6种有机硅表面活性剂的表面张力有上升趋势;6种有机硅表面活性剂溶液与胜利油田G89区块原油的界面张力分别为0.025,0.30,0.50,0.11,0.43和0.63 mN/m;选用表面活性较好的ASiE-500进行CO2驱油实验,能进一步提高原油采收率11.44%。

Abstract: Six kinds of organosilicone surfactant,ASiE-500,ASiD2-500,ASiD4-500,ASiE-700,ASiD2-700 and ASiD4-700 were synthesized with allyl polyethylene glycol,epoxy chloropropane,hydrogen-containing silicone oil and organic amines as main starting materials.The targeted products were characterized with FT-IR and 1H NMR.Then their surface tension and interfacial tension were investigated.Afterwards,their application in CO2 flooding laboratory experiment was conducted and examined.Results of the experiments showed that solutions of the targeted products display lower surface tension,and in which,solution of the targeted product ASiE-500 displays lowest surface tension of 25.3 mN/m at 25 ℃.With the increase of concentration of NaCl and/or MgCl2,the surface tension of solution of the targeted products rises.The interfacial tension between the crude oil produced from Section G89 of Shengli Oilfield and solution of the above said targeted products was measured as 0.025,0.30,0.50,0.11,0.43 and 0.63 mN/m respectively.By choosing ASiE-500 that displays better activity to do the CO2 flooding,the enhanced oil recovery (EOR) can be further improved for 11.44%.

Key words: silicone surfactants, surface tension, interfacial tension, CO2 flooding
