摘　　要：系统地考察了离子强度和碱浓度对萘磺酸盐与原油中活性组分间协同效应的影响。研究表明,最佳协同效应需要最佳物化条件(碳酸钠浓度为0.005%,氢氧化钠浓度为2.5×10-3 mol/L,离子强度为0.3 mol/kg);另外,还考察了钙镁离子对原油、萘磺酸盐及碱水体系界面张力的影响,实验结果表明,钙镁离子对石油萘磺酸盐与胜利原油活性组分协同效应影响与碱型、碱浓度和离子强度有关。The effect of ionic strength and alkali concentration on synergistic effect between alkylnaphthalene sulfonates and surthce-active components in Crude oil is systematically investigated, the resuhs show that an optimal physico-chemical condition （ CNa2CO3 =0.005 wt%, CNaOH =2.5 ×10^-3 mol/L, 1--0.3 mol/kg ） was necessary to the best synergism. In addition, the effect of calcium ion and Mg^2＋ ion on interfacial tension in surfactant/ alkali/ acidic crude oil is also be investigated, the studies show that above effect is relative to alkali type, pH value, ionic strength.
