Study on Identification and Detection Methods of Anionic Surfactants for Oil Displacement
Aiming at the problem that it is difficult to detect the anionic surfactant for oil displacement under the condition of complex ions in the oil well produced fluid,the identification and detection method of anionic surfactant for oil displacement in the oil field produced fluid was established by using the high performance liquid chromatography system,and the accuracy and effectiveness of the method were verified.This method has the characteristics of fast and accurate,simple operation and strong applicability.At the same time,the separation method of surfactant from oilfield produced fluid(including crude oil and sewage)was determined,which had good field application effect,providing technical support for the field test of anionic surfactant for oilfield oil displacement.
