Research progress and development of chemical wax removal and prevention system
In view of the difficulties of wax formation during the production/transportation of crude oil and the huge economic losses caused by the wax plugging of oil wells.Studying wax removal and prevention technology is of great significance to ensure the high efficient production of crude oil.The mechanism and the influence of different factors on the characteristic of wax precipitation are summarized.The research progress and current situation of chemical wax removal solvent are reviewed,including the mechanism and research achievement of oil-soluble,water-soluble and emulsion removal solvent.To solved the high car-bon number wax deposition and asphaltene-wax co-position deplugging solvent is proposed as the develop-ment trend of wax removal solvent,hoping to provide reference for further research and development of wax removal and prevention.
