Abstract
The invention provides a high-polymer crude oil activator, and a preparation method and application thereof. The preparation method comprises the following step: carrying out copolymerization reaction on acrylamide, acrylic acid or alkali metal salts thereof, 2-acrylamido-2-methylpropanesulfonic acid or alkali metal salts thereof, amphoteric functional monomers disclosed as Formula I, and amphiphilic functional monomers disclosed as Formula II. The high-polymer crude oil activator provided by the invention can effectively lower the viscosity of viscous oil in crude oil exploitation and increase the fluidity of the crude oil produced liquid.
Description
Technical field
The invention belongs to technical field of petrochemical industry, and in particular to a kind of macromolecule crude oil activating agent and preparation method thereof with
Using.
Background technology
Thickened oil recovery is worldwide common difficulty.Because viscosity of thickened oil is big, gum asphaltic content is high, on ground
Flowing is difficult in layer, pit shaft and petroleum pipeline, while oil and water mobility ratio greatly, is easily caused, water-free oil production period is short, oil well water breakthrough is fast,
The problems such as Produced Liquid moisture content is high and stratum easily shakes out.
Thickened oil recovery method can be divided mainly into injection fluid exploitation, such as hot water flooding, steam soak, steam drive etc., and
Yield increasing type mining type, such as horizontal well, compound branch well, electrical heating etc..Chemical viscosity reduction agent can effectively disperse for viscous crude, breast
The effect such as change, significantly reduces viscosity of thickened oil, reduces viscous crude flow resistance in stratum and pit shaft, advantageously reduces recovery process energy
Consumption, reduction exhaust emission, raising heavy oil production speed and recovery ratio, thus as the important content of viscous crude enhanced recovery, application
Prospect is very wide.
The content of the invention
It is an object of the invention to provide a kind of macromolecule crude oil activating agent and preparation method thereof.
Macromolecule crude oil activating agent provided by the present invention is prepared by the method comprising the following steps：
So that acrylamide, acrylic acid or its alkali metal salt, 2- acrylamide-2-methylpro panesulfonic acids or its alkali metal
The amphipathic function monomer shown in both sexes function monomer and Formula II shown in salt, Formulas I is copolymerized, and obtains the high score
Sub- crude oil activating agent；
In Formulas I, R1It is H or CH3, G1It is Cl-Or Br-, G2It is H+、Na+、K+Or NH4 +, m is the integer of 3-12, preferably 3-8；
In Formula II, R2It is H or CH3, R3And R4It is the alkyl of carbon chain lengths 1-16, preferably carbon chain lengths are the alkyl of 4-12；
G3And G4It is H+、Na+、K+And NH4 +。
In the comonomer of above-mentioned macromolecule crude oil activating agent, acrylamide account for the percentage of monomer gross mass for 10~
90%, preferably 20~80%, concretely 56.5%, 57%, 65% or 72%；It is total that acrylic acid or its alkali metal salt account for monomer
The percentage of quality is 5~50%, preferably 10~35%, concretely 10%, 11%, 12% or 15%；2- acrylamides
The percentage that base -2- methyl propane sulfonic acids or its alkali metal salt account for monomer gross mass is 5~40%, preferably 5~25%, specifically may be used
It is 8%, 15%, 22% or 25%；The percentage that both sexes function monomer shown in Formulas I accounts for monomer gross mass is 0.1~15%, excellent
Elect 1~10% as, concretely 4.5%, 6.5% or 8.5%；Amphipathic function monomer shown in Formula II accounts for monomer gross mass
Percentage is 0.1~8%, preferably 0.5~3%, concretely 0.5%, 1.5%, 2.5% or 3.0%.
In the above method, the copolyreaction can be carried out in water.
The copolyreaction can be carried out under inert gas shielding.
The inert gas concretely nitrogen.
Auxiliary agent, the auxiliary agent can be also added to be selected from lauryl sodium sulfate, 12 in the reaction system of the copolyreaction
Sodium alkyl sulfonate, cetyl trimethylammonium bromide, alkylpolyoxyethylene sodium sulphate, alkylpolyoxyethylene phosphorus
