摘要

综述了石油磺酸盐与重烷基苯磺酸盐的乳化性能,调研了2种表面活性剂与不同材料混合后形成的复配体系的乳化性能变化,以及乳化能力与原油采收率的关系,并对乳化驱油在油田现场的应用进行了总结与展望。

Abstract

The emulsification performances of petroleum sulfonates and heavy alkyl benzene sulfonates are summarized,the changes in emulsification performance of the composite system formed by mixing these two surfactants with different materials are investigated,and the relationship between emulsification ability and crude oil recovery rate is explored.It also summarizes and prospects the application of emulsification flooding in oil fields.
