Description
Technical field
The present invention relates to a kind of demulsifier and preparation method thereof, be specifically related to a kind of heavy high-acid crude oil rapid demulsifier and
Its preparation 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 on market for the shortcoming that the demulsifier de-emulsification speed of heavy high-acid crude oil is slow, greatly limit its range of application.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is to provide a kind of heavy high-acid crude oil fast emulsion breaking
Agent and preparation method thereof.
For solving prior art problem, the present invention provides following technical scheme:
A kind of heavy high-acid crude oil rapid demulsifier, is made up of the raw material of following weight portion: rosin amine polyoxyethylene polyoxypropylene
Ether 13-17, alkylphenol-formaldehyde resin polyoxyethylene polyoxypropylene ether 11-16, polyoxyethylene polyoxypropylene tetramethylolmethane ether 10-
15, methyl glucoside polyethenoxy ether 8-13, different cetearyl alcohol polyoxyethylenated alcohol stearate 6-11, glycerin polyoxyethylene ether
Laurate 5-10, cocamido propyl betaine 4-8, epoxychloropropane-diethanolamine copolymer 7-12.
The preparation method of a kind of heavy high-acid crude oil rapid demulsifier, comprises the following steps:
(1) by rosin amine polyoxyethylene polyoxypropylene ether, methyl glucoside polyethenoxy ether, different cetearyl alcohol polyoxyethylenated alcohol
Stearate, cocamido propyl betaine, epoxychloropropane-diethanolamine copolymer mix homogeneously, then at power be
700-800W, rotating speed is magnetic agitation 5-6min under conditions of 600-700r/min, obtains compound A；
(2) by remaining raw material mix homogeneously, being then 600-700W at microwave power, rotating speed is the condition of 500-600r/min
Lower microwave stirring 6-7min, obtains compound B；
(3) being mixed homogeneously with compound B by the compound A obtained, be then 400-500W at ultrasonic power, supersonic frequency is
Ultrasonic vibration 20-30min under conditions of 30-40KHz, gets product.
The method have the benefit that
The present invention uses rosin amine polyoxyethylene polyoxypropylene ether, alkylphenol-formaldehyde resin polyoxyethylene polyoxypropylene ether, polyoxy
Ethylene polyoxypropylene tetramethylolmethane ether, different cetearyl alcohol polyoxyethylenated alcohol stearate, epoxychloropropane-diethanolamine copolymerization
The demulsifier that the raw materials such as thing prepare has the features such as de-emulsification speed is fast, dewatering efficiency is high, consumption is few, it is adaptable to heavy peracid
Crude oil fast emulsion breaking.
