The Wide Application of Fluorocarbon Surfactant in Foam Extinguishing Agent

Some fluorocarbon surfactants are suitable for demulsifier of crude oil. Demulsification with surfactant is that it can be adsorbed on the oil-water interface film, so that the strength of the film is greatly reduced, so as to achieve crude oil demulsification. In addition, fluorocarbon surfactants can also be used as acid fracturing fluid and drainage aid to improve the production rate of oil and gas Wells.

It can be seen that the use of fluorocarbon surfactants as oil displacement agents in the petroleum industry is limited in many ways. It mainly lies in how to find the matching hydrocarbon surfactant in technology, reduce the cost and solve the problems of ultra-low interfacial tension, oil foam resistance, stable performance and so on. At present, the application of fluorocarbon surfactants in oil fields in the domestic market is actually to avoid the oil-repellent nature of fluorocarbon surfactants, and to use its strong acid and alkali resistance, mainly used as acidizing fracturing fluid, drainage aid and so on.

The main industrial applications of fluorocarbon surfactants in tertiary oil recovery, petroleum fire protection and other fields are introduced. The main issue of current concern is how to develop low-cost formulations and processes in each application field, which requires breaking industry barriers and increasing collaboration between industries. Many applications of carbon surfactants are protected by patents, which restricts the development of their applications to some extent. In addition, the application of new fields of research in the future to make greater investment, with the continuous development of the market economy and the continuous increase of technical strength, it is inevitable to have a deeper understanding of its nature, so that its application field continues to expand, so that fluorocarbon surfactants can continue to serve the industrial development.
