摘　　要：针对大庆油田小井距生物表面活性剂复合体系先导性矿场试验 ,利用自行研制并生产的6 0t鼠李糖脂发酵液 (RH)与其他表面活性剂进行复配 ,优选出了适合于大庆油田小井距的三元复合体系配方。通过对配方的综合性能评价 ,证明RH可以拓宽超低界面张力区域 ,降低表面活性剂的吸附滞留量 ,三元复合体系驱油效率比水驱提高 2 0 %以上。另外 ,在驱油效率相同的情况下 ,降低ORS41用量 5 0 % ,成本核算表明 ,生物表面活性剂三元复合体系成本比原三元复合驱矿场试验化学剂成本节省 30 %以上。This paper aims at the bio-surfactant combination system used in small well spacing pilot test of Daqing oil field. After the 60 tons RH liquid that we researched and produced by ourselves was combined with other surfactant, we screened and optimized the formulation of ASP combination system that fit small well spacing. Based on the evaluation of the general properties of the formulation, we confirm that RH can increase the range of ultra-low interfacial tension area and reduce the occlusion and adsorption...
