Description
Technical field
The present invention relates to a kind of demulsifier and preparation method thereof, be specifically related to a kind of super-viscous oil high-efficient demulsifier and preparation thereof
Method.
Background technology
Along with oil field large area is taked to increase water filling, the measure of steam injection raising oilwell produced fluid amount, oil well produced liquid is aqueous
Rate rises rapidly；Meanwhile, the extensive application of various oil recovery auxiliary agents also makes the Produced Liquid group of crude oil, particularly viscous crude and super-viscous oil
Become become more complicated, cause the efficient breakdown of emulsion of viscous crude and super-viscous oil have become as affect cost for oil production, crude quality, yield and
Control the key technology that oilfield environment pollutes.
Demulsifier is a kind of surfactant, and it can make the liquid structure of emulsifying shape destroy, to reach each in emulsion
Be separated the purpose come.Crude oil demulsification refers to that the chemical action utilizing demulsifier is by oil and water in the oil-water mixture of emulsifying shape
Separate, make up to the purpose of crude oil dehydration, make water content reach requirement, to ensure that crude oil exporting contains water quality standard energy.Existing
With the presence of the shortcoming that demulsifier demulsification performance is the best, dehydration rate is low for super-viscous oil on market, greatly limit its application model
Enclose.
