Abstract
The invention relates to high molecular synthesis technology, in particular to an oil-based viscosity reducer for raw oil conveyed through a pipeline, and belongs to the technical field of chemical industry. The oil-based viscosity reducer is mainly used for reducing the viscosity of the raw oil conveyed through a long-distance pipeline and is prepared by the following steps of: synthesizing terpolymer by using higher alcohol acrylate, maleic anhydride and acrylamide in a molar ratio of 20-70 percent to 10-50 percent to 10-50 percent; synthesizing amide by using oleic acid and diethylenetriamine in a molar ratio of 20-80 percent to 20-80 percent; heating and uniformly mixing ethylene vinyl acetate copolymer, terpolymer, amide and another surfactant in a molar ratio of 0-80 percent to 0-80 percent to 5-60 percent to 5-60 percent in a compounding mode; and then cooling the obtained product and crushing the product into grains to obtain the oil-based viscosity reducer product.
Description
Technical field
The present invention relates to a kind of macromolecule synthesising technology, be specifically related to a kind of oil base viscosity-depression agent that pipeline oil is used that is used for, be mainly used in the viscosity reduction of long-distance pipe conveying crude oil, belong to chemical technology field.
Background technology
A large amount of viscous crude that China abounds with, though when exploitation, can adopt the water-based emulsion agent to carry out reducing viscosity by emulsifying, but collecting defeated when carrying in particular for long-distance pipe, because crude oil water containing is (pipeline oil is moisture to be no more than 1.5%) seldom, generally do not adopt the mode of reducing viscosity by emulsifying to carry, do not have suitable oil base viscosity-depression agent to be used for industrial production at present.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of oil base viscosity-depression agent that pipeline oil is used that is used for is provided, this oil base viscosity-depression agent employing vinylformic acid high-carbon alcohol ester and MALEIC ANHYDRIDE, acrylamide synthesis of ternary multipolymer, its mol ratio is: 20～70%: 10%～50%: 10%～50%; Adopt oleic acid and diethylenetriamine synthesizing amide, its mol ratio is: 20%～80%: 20%～80%; With ethylene vinyl acetate copolymer, terpolymer, acid amides and other tensio-active agents, according to 0～80%: 0～80%: 5%～60%: 5%～60% mol ratio, in composite mode, heating mixes, be ground into particle after the cooling then, obtain oil base viscosity-depression agent product.
The present invention realizes with following technical scheme: a kind ofly be used for the oil base viscosity-depression agent that pipeline oil is used, it is characterized in that: this oil base viscosity-depression agent employing vinylformic acid high-carbon alcohol ester and MALEIC ANHYDRIDE, acrylamide synthesis of ternary multipolymer, its mol ratio is: 20～70%: 10%～50%: 10%～50%; Adopt oleic acid and diethylenetriamine synthesizing amide, its mol ratio is: 20%～80%: 20%～80%; With ethylene vinyl acetate copolymer, terpolymer, acid amides and other tensio-active agents, according to 0～80%: 0～80%: 5%～60%: 5%～60% mol ratio, in composite mode, heating mixes, be ground into particle after the cooling then, obtain oil base viscosity-depression agent product.
Described tensio-active agent is wherein one or more of alkylphenol-polyethenoxy (4) ether, alkylphenol-polyethenoxy (7) ether, polyethylene polyamine polyoxyethylene polyoxypropylene ether, sorbitan monostearate polyoxyethylene (20) ether or sorbitan mono-oleic acid ester.
Advantage of the present invention is: this product is made up of polarity stronger polymkeric substance and tensio-active agent, and the polymeric constituent that polarity is stronger both can play nucleus, eutectic and adsorption with wax effectively, can play dissemination with the gum asphalt in the oil again; The gum asphalt of surface active agent composition in can dispersed oil, and reduce association between the gum asphalt effectively, thus improve the low temperature flowability of crude oil, reduce the viscosity of crude oil.Be used for long distance oil pipeline, can improve pipeline transmission capacity.
