| 摘 要： | 通过原油沥青分散性试验，考查了不同种类的石油磺酸盐对原油沥青质的分散性能，以便寻求一种评价驱油用表面活性剂应用性能的简便方法。试验结果表明，作为对现有标准评价方法的补充，该试验方法具有简单、实用、数据对比性强等特点，对于石油磺酸盐产品常规性能的例行检验尤为适用。与此同时，三种不同类型的石油磺酸盐产品对原油沥青质分散性的数据对比表明，具有长链稠环或短侧链多环芳烃结构的石油碘化产品，对于地层残余油沥青质的分散性较好，比普通的石油磺酸盐更适宜作为开采地下残余原油的实用型驱油用表面活性剂而使用。

| Abstract: | To find out a sinpler way to evaluate the applicability of surfactants for oil displacement,an experimetal study is made on the dispersivity of various oil sulfonates to crude asphaltene.Experiment results show that as a supplement to the currently-used standard evaluating method,this method is simpler,more applicable,and stronger in data comparability.Meanwhile,data comparison indicates that oil sulfonate with the structure of PAH with long condensed rings or short lateral chains is more suitable than ordinary oil sulfonate to be used as a surfactant for oil displacement in residual oil recovery as it has better dispersivity to asphaltene in stratingraphic residual oil |
