Oil demulsifier for oil extraction is subjected to oil-water separation oilfield chemicals, its depth and demulsification principle is to adhere to the emulsion droplet interface, replacing the emulsifier and destroy the surface film, the film clad droplet coalescence release so that the oil and water two-phase separation occurs. Since oil extraction technology is not from the initial water to oil heavy oil thermal recovery, but also to alkaline flooding, surfactant flooding, polymer flooding and EOR, the crude oil in the varnish, asphalt, naphthenic acid emulsification substance, fatty acids and salt, combined with a variety of crystalline paraffin having introduced artificial surfactant, making recovery of crude oil emulsions exhibits form. Also, because the new technology constantly advancing, now most of the oil has entered the high water content of the crude oil emulsion from the W / O type into O / W type, increasing the difficulty of crude oil demulsification dehydration, but also makes crude oil demulsifier in the structure, composition and other aspects of the mechanism of demulsification also changed a lot, and for over a demulsifier for crude oil should be required to have a strong surface activity, good wetting properties, sufficient flocculation, coalescence better effect. To meet the oil needs to ensure that crude oil demulsification effect, but also greatly promoted the development of the process of crude oil demulsifier.
