英文摘要	用鼠李糖脂复配体系对大庆油田采油七厂葡北三断块进行生物表面活性剂驱油技术研究及现场试验.结果表明:鼠李糖脂的复配驱油体系在有效质量分数(0.125％～1.0％)低而宽的范围内,与葡北油水之间的界面张力大幅下降(10-2 mN/m数量级)；在模拟油层渗透率的天然岩心上注入0.5Vp(Vp为孔隙体积)的鼠李糖脂复配驱油体系,采收率比水驱提高7.9％～9.3％;13个月驱油累积增油2014 t,平均单井增油224 t,日产油量由试验前的1.5t上升到1.85 t,含水率最低下降1.5％,投入产出比达到1∶2.4.; The bio-surfactant flooding technology was researched. The field test for rhamnolipid combined displacement system was carried out in Pubeisan fault block of No. 7 Oil Production Plant of Daqing Oilfield. The results show that rhamnolipid combined displacement system with low and wide effective concentration (0.125%-1.0%) can reduce interfacial tension with oil and water in Pubei to the order of magnitude of 10-2 mN/m. Injection of 0.5 VP (pore volume) of rhamnolipid combined displacement system in natural core simulating reservoir permeability can increase the oil recovery efficiency by 7.9%~9.3% compared with water flooding. During 13 months of field test, the cumulative incremental oil amounts to 2014 t, with an average of 224 t for individual well. Daily oil production increases from 1.5 t/d to 1.85 t/d, average water cut decreases by 1.5%, and input-output ratio is 1:2.4.; 国家“863”项目; 中国石油天然气股份有限公司科技开发项目; EI; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 2; 168-171; 36
