摘　　要：考察了NaCl、CaCl2质量浓度对十二烷基二苯醚双磺酸钠（C12MADS）水溶液与液体石蜡间界面张力、在石蜡膜上接触角的影响,并以液体石蜡为模拟油对硅胶进行改性来模拟油藏,进行了洗油率研究.在所考察的无机盐质量浓度范围内（NaCl 50~250g/L,CaCl21~10 g/L）,C12MADS水溶液与液体石蜡间界面张力、在石蜡膜上的润湿性变化较小,洗油率比水驱提高5%~10%.Effects of NaCl and CaCl2 concentration on interfacial tensions of the dodecyl diphenyloxide disulfonate（C12MADS） aqueous solution against liquid paraffin and the contact angle on paraffin film were investigated.Washing oil efficiency was studied,and liquid paraffin was used as mimic oil and silica gel containing oil on its surface as mimic oil reservoir.In the range of salt concentration studied（NaCl 50-250g/L,CaCl21-10g/L）,the interfacial tensions and the wettability had a little change,and the washing oil efficiency enhanced 5%-10% compared to use water flooding.
