-
Paragraph 0116-0120, (2020/05/08)
The invention provides a quaternary ammonium salt surfactant, a preparation method and applications thereof, wherein the structure of the quaternary ammonium salt surfactant is represented by a formula (I), and each group is defined in the specification. The quaternary ammonium salt surfactant disclosed by the invention can be used as an efficient and low-consumption wetting agent in the field oftertiary oil recovery, and can effectively convert the surface of a carbonate oil reservoir wrapped by crude oil into water wettability or neutral wettability in the tertiary oil recovery process to achieve wetting reversal, so that the oil washing efficiency can be improved.
