摘要
为考察原油成分对复合体系界面活性的影响，将原油通过实沸点蒸馏法切割成不同的馏分，对各馏分与三元体系的动态界面张力进行了测定。还探讨了馏分油的乳化液稳定性及重组分对乳化液稳定性的影响。研究结果表明：与三元体系的界面张力，轻馏分最低，其次是重组分，再次是沸点依次升高的中间馏分；在轻馏分中加入重组分可以进一步降低界面张力；馏分油与二元（ Ａ／Ｓ） 体系形成的乳状液，其稳定性随馏分沸点升高而降低，加入重组分可提高乳状液的稳定性。
In order to determine the effects of crude oil composition on interfacial tensions for combinational flooding systems, the crude oil was cut into four fractions by boiling distillation: X 1 with b.p .<200℃; X 2, 200-300℃; X 3,300-360; X 4,>360℃. The dynamic interfacial tensions between the fractions and an ASP flooding solution were measured and arranged in order for these fractions as X 1<X 4<X 2<X 4; adding X 4 into X 1 decreased the interfacial tension of the latter. The stabilily of fraction/AS flooding solution emulsions decreased for the fractions in order X 1>X 2>X 3 and adding X 4 into these fractions increased the stability of their emulsions with AS solution.
