Embodiment 1

[0036] First cut the polyalphaolefin into less than 5mm in the pelletizing equipment 3 Then, in 1 / 1 water and ethylene glycol cooling medium, pre-grind the polyalpha-olefin particles with a colloid mill, filter to obtain polyalpha-olefins below 600 μm, and add 2 % superfine aluminum oxide, 2% macromolecular wax and 3% zinc stearate, the cooling medium water consumption is 2 times of the polyalpha-olefin weight; finally 30kg ethylene glycol butyl ether, 20kg butanol , 10kg of Pingpingjia AEO-9, 40kg of pre-ground polyalphaolefins were homogenized in a high-shear device for 30 minutes to obtain a stable suspension dispersion system.

Embodiment 2

[0038] First cut the polyalphaolefin copolymer into less than 5mm in pelletizing equipment 3 Then in 1 / 1 water, ethylene glycol cooling medium, the polyalpha-olefin copolymer particles are pre-ground with a colloid mill, adding 1% talcum powder and 2% polyalpha-olefin copolymer weight when grinding. % polyethylene wax and 5% calcium stearate, the cooling medium ethylene glycol consumption is 2 times of the weight of the polyalpha-olefin copolymer, and part of the cooling medium is removed by filtration to obtain a polyalpha-olefin copolymer with a solid content of 60%, Poly-α-olefin copolymer slurry whose dispersion scale is below 600 μm; finally, 20kg of polyethylene glycol 200, 10kg of Pingping plus OS-15, and 70kg of pre-ground poly-α-olefin copolymer slurry were homogenized in a high-shear device After massifying for 60 minutes, a stable suspension dispersion system was obtained.

Abstract

The invention discloses a drag reduction object which comprises the following components in percentage by weight: 5 to 35 percent of parting agent, 5 to 40 percent of dispersing agent and over 30 percent of poly-alpha-olefin or copolymer of the poly-alpha-olefin, wherein the parting agent is selected from one or more of a powdered inorganic mineral material, organic wax, solid alcohol, stearate and fatty alcohol-polyoxyethylene ether; and the dispersing agent is selected from one or more of water, alcohol, cellosolve, polyether polyol, fatty alcohol-polyoxyethylene ether, alkyl phenyl polyoxyethylene ether, D-sorbitol polyoxyethylene ether, fatty glyceride and fatty acid. The invention also discloses a method for preparing the drag reduction object. The poly-alpha-olefin or copolymer of the poly-alpha-olefin content in the drag reduction object is up to over 30 percent, so that the transportation cost is reduced; a drag reduction effect can be effectively achieved; and the drag reduction rate is nearly 30 percent. The preparation process is finished at room temperature; and steps of refrigerating at low temperature, smashing, grinding and the like are eliminated.

Description

technical field [0001] The invention relates to the technical field of petroleum, in particular to an ultrahigh molecular weight polyolefin drag reducer and a preparation method thereof. Background technique [0002] At present, polyalphaolefins or their copolymers are often used to reduce the resistance of oil pipelines and reduce the energy consumption of oil transportation, so polyalphaolefins or their copolymers are called drag reducers in the oil transportation process. Generally, polyα-olefins or their copolymers obtained by polymerization are viscoelastic blocks, which are not suitable for direct injection into oil pipelines, and can only be used after being dissolved in a solvent or dispersed into a slurry suspension after being crushed. [0003] The use of hydrocarbon solvents to dissolve polyalpha-olefins or their copolymers is to dissolve the polymers into colloidal liquids with hydrocarbon solvents after pelletizing. Although the process of this method is simple...
