Description
Technical field
The present invention relates to petrochemical industries, and in particular, to a kind of acrylamide copolymer and preparation method thereof and answers
With.
Background technology
Polymer displacement of reservoir oil is mainly the polymer solution by injecting certain scale, increases displacement fluid viscosity, reduces oil reservoir
Water phase permeability come reduce mobility ratio, adjustment intake profile, with achieve the purpose that improve displacement phase volume, and then improve harvesting
Rate.
As main polymer oil-displacing agent, partially hydrolyzed polyacrylamide (PHPA) (HPAM) is in conventional oil reservoir tertiary oil recovery
(EOB) in technology, large-scale promotion and application have been obtained, important function has been played for oilfield stable production and volume increase.With routine
The reduction of reservoir reserve, high temperature and high salt oil deposit make the application of HPAM be faced with many problems, and it is high to be mainly reflected in exploitation high temperature
The compound action that dissolved oxygen generates in high temperature, with high salt and solution when salt oil deposit makes HPAM solution viscosities be greatly reduced, and causes
HPAM oil displacement efficiencies are not notable.Studies have shown that when temperature is higher than 70 DEG C, the acylamino- hydrolysis of HPAM generates carboxyl and significantly adds
Play, when degree of hydrolysis reaches 40% or more, carboxyl is just easy to and Ca in solution2+、Mg2+Ion generates precipitation, and solution viscosity is made to damage
It loses.In addition, at high temperature, there are when dissolved oxygen, can also cause main polymer chain fracture to keep solution viscous in oxygen and solution in air
Degree is remarkably decreased.
In order to improve the temperature-resistant anti-salt performance of polyacrylamide, a large amount of tackling key problem researchs have been carried out both at home and abroad, mainly around poly-
Chain scale, chain size distribution, construction unit composition, the micro-sequential structure for closing object carry out a large amount of correlative study work, such as heatproof
Salt resistance monomer-polymer, hydrophobic associated polymer, amphoteric polymer, composite polymer, comb polymer, template polymer and
Surface-active polymer etc..Such as entitled " low temperature of AMPS/AM copolymers synthesizes and performance " (Chang Zhiying, polymer material science
With engineering, 1997,13,16) with acrylamide (AM) and heat-resistant salt-resistant monomer 2- acrylamide-2-methylpro panesulfonic acids (AMPS)
Copolymerization bipolymer.As CN101260171A discloses a kind of comb-type structure activity polymer and its preparation process and answers
With by the monomer copolymerizables such as polyurethanes surface-active macromonomer and acrylamide at tackifying and reduction interfacial tension target
Product.The polymer that above two method obtains respectively has its feature, certain performances for example temperature tolerance, salt-resistance, shear resistant and
More traditional polyacrylamide increases really in surface-active index, but technological operation is relatively cumbersome, and obtains product point
Son amount is small (being no more than 20,000,000), and the use of polymer is caused to be restricted.
Invention content
It is an object of the invention to overcome the drawbacks described above of the prior art, a kind of acrylamide copolymer, Yi Zhongbing are provided
The preparation method of acrylamide copolymer, the acrylamide copolymer prepared by this method and the acrylamide copolymer are answered
