With the continuous improvement of crude oil extraction and refining technology, the
composition and properties of produced liquid are greatly different from those
produced by traditional production methods. Therefore, the requirements for
demulsifier performance are constantly changing and improving. At present, the
function and efficiency of some crude oil emulsion breakers are difficult to meet the
engineering requirements. Based on this, this paper first analyses the types and
structure of crude oil emulsion breakers, then studies the research and development
status and application status of crude oil emulsion breakers, and finally gives the
research and development history, evaluation methods and future development
direction of crude oil emulsion breakers.
