Abstract
The invention discloses a kind of dissaving polymer heavy crude thinners and preparation method thereof, its technical solution is: octadecyl methacrylate, styrene and ethylene glycol dimethacrylate are dissolved in dimethylbenzene, in nitrogen environment, initiator benzoyl peroxide is added, 6h is reacted under the conditions of 70 DEG C and obtains dissaving polymer heavy crude thinner.The heavy crude thinner viscosity reducing effect is good, preparation is simple, can reduce the defeated temperature of collection of viscous crude, has broad application prospects at the defeated aspect of thickened oil recovery sum aggregate.
Description
Technical field
The present invention relates to a kind of dissaving polymer heavy crude thinners and preparation method thereof, belong to oil field chemical field.
Background technique
China's viscous crude is resourceful.According to statistics, China successively has found a viscous crude field more than 70 in 12 basins, establishes
5 great development production districts, yield have accounted for the 10% of national petroleum total output, and viscous crude positive performer in China's energy resource structure is more next
More important role.But viscous crude molecular structure is complicated, heavy constituent content is high, and viscosity is big, defeated brings to the exploitation sum aggregate of viscous crude
The difficulty that arrives very much.
For a long time, mainly use that heating, viscosity reducing collection is defeated, thin oil blending visbreaking collection is defeated, reducing viscosity by emulsifying collection is defeated to viscous crude both at home and abroad
Etc. modes.Heating, viscosity reducing fuel consumption is big, at high cost;Thin oil blending visbreaking is not only limited by thin oil source, but also mixes viscous crude
Thin oil according to viscous crude calculation of price, it is low in economic efficiency;Thick-oil emulsified adhesive-reducing collection is defeated to be will appear post-processing (as being dehydrated) and asks
Topic, and it is not suitable for low water-bearing crude oil.
Oil-soluble viscosity reducer have many advantages, such as viscosity reduction dosage is few, viscosity reducing effect is good, without post-processing, therefore, receive extensively
Concern.Oil-soluble viscosity reducer viscosity reduction primarily directed to viscous crude component structure and a kind of viscosity reduction method for studying.This method
The oil-soluble viscosity reducer molecular structure of designed synthesis is similar to viscous crude component structure, using nonpolar Long carbon chain as main chain, again
Containing highly polar side-chain radical, nonpolar alkyl chain is soluble in viscous crude, plays infiltration, peptizaiton, and highly polar
Side-chain radical can be formed with the colloid in viscous crude, the polar group in asphalitine than original stronger hydrogen bond, and colloid, pitch are caused
Hydrogen bond in matter original structure destroys;In addition, the benzene ring structure being interspersed in viscosity reduction agent molecule can be with the virtue in colloid, asphalitine
Ring or heteroaromatic form Π-Π conjugation or sedimentation, and regular, the close stratiform packing structure for keeping it original is destroyed, and
And thinner Molecular Adsorption can prevent it from assembling again on scattered asphalitine surface, to significantly reduce the viscosity of viscous crude.
Summary of the invention
Good, simple process that the purpose of the present invention is to provide a kind of viscosity reducing effects and it is low-cost for heavy oil pipeline it is defeated
Send heavy crude thinner and preparation method thereof.
To achieve the goals above, the present invention provides following technical scheme.
A kind of dissaving polymer heavy crude thinner, structural formula are as follows:
Wherein R is positive octadecyl;X, y, z is monomer mole ratio, x ﹢ y ﹢ z=1.
It is prepared the following steps are included: octadecyl methacrylate, styrene and ethylene glycol dimethacrylate is molten
In dimethylbenzene, in nitrogen environment, initiator benzoyl peroxide is added, reaction 6h is obtained hyperbranched under the conditions of 70 DEG C
Polymer heavy crude thinner.
The molar ratio of octadecyl methacrylate and styrene is 3~5:1.
The dosage of ethylene glycol dimethacrylate is 0.02~0.05%.
The present invention compared with the prior art, the beneficial effect is that:
(1) heavy crude thinner of the invention is adaptable, is suitble to the viscous crude of different water cut and different compositions;
(2) heavy crude thinner dosage of the invention is small, viscosity reducing effect is good;
(3) heavy crude thinner site construction technology of the invention is simple, does not need to post-process.
