Abstract
The invention discloses a water dispersible profile control agent for oil extraction and a preparation method thereof. The water dispersible profile control agent comprises the following components in parts by weight: 70-150 parts of acrylamide, 5-10 parts of anionic monomer, 5-10 parts of cationic monomer, 1-5 parts of hydrophobic monomer, 15-55 parts of dispersant, 30-85 parts of inorganic salt and 230-500 parts of deionized water. By virtue of water in water dispersion polymerization, the product is instant, so that the liquid preparation time and the curing time of a conventional polyacrylamide solution are shortened. A cationic chain link is introduced based on a conventional gel, so that gel molecules and rocks with negative electricity firmly adsorb so as to increase the flow resistance of water and improve the scouring resistance of the gel. The water dispersible profile control agent is low in initial viscosity, good in pumping property, simple in construction process and small in environmental damage. The water dispersible profile control agent is good in biological stability, and the profile control period of validity is over half a year. The product is obtained by virtue of water in water dispersion polymerization and is instant in the using process.
Description
Technical field:
What the present invention relates to is that a kind of aqueous dispersion type recovers the oil with amendment and preparation method thereof.
Background technology:
The research of China's water plugging and profiling technology can be traced back to late 1950s with application, oilwell water shutoff mainly take 60 to the seventies as main, the beginning of the eighties is along with the appearance of polymkeric substance and cross linked gel thereof, Profile Control in Injection Well technology develops rapidly, no matter be water blockoff or profile control, all take high strength blocking agent as main, and the mechanism of action mostly is physical barriers formula and stops up.The nineties, oil field enters high water-cut stage, and profile control and water plugging technology also enters the prosperous phase of development, is processed to develop into take profile control and water plugging measure as the main block comprehensive regulation by individual well.Enter after 21 century, oil field is general high moisture, the primary heterogeneous body of oil reservoir and long-period water drive are further aggravated nonuniformity, in oil reservoir, form gradually high passage or the macropore of oozing, make reservoir pressure field, streamiline field forms set, between oil and water well, form current advantage passage, cause water drive " short circuit ", have a strong impact on reservoir water drive development effectiveness, in addition the limitation of high water-cut reservoir present situation being familiar with, conventional profile control and water plugging technology cannot meet oil reservoir development needs, thereby, deep profile controlling (transfer drive) technology that effect and impact effect are larger obtains fast-developing, the theoretic knowledge and the technical development that improve water drive have entered a new stage.
For a long time, it is main underground crosslinked that the amendment using on the most of oil field of China generally be take polyacrylamide, its plastic condition is harsh, heatproof endurance of cutting is poor, salt tolerance is poor, adsorptive capacity is large, sealing ratiod is low, therefore also there are at present a lot of problems in the very high polymer flooding of popularization degree, therefore improve Development Response of Oilfield, application deep transfer drive technology has great importance.
Summary of the invention:
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of aqueous dispersion type recover the oil with amendment and and preparation method thereof.
In order to solve the existing problem of background technology, the present invention by the following technical solutions:
A kind of aqueous dispersion type oil recovery amendment, it is comprised of acrylamide, anionic monomer, cationic monomer, hydrophobic monomer, dispersion agent, inorganic salt, deionized water, by weight, contain 70-150 part acrylamide, 5-10 part anionic monomer, 5-10 part cationic monomer, 1-5 part hydrophobic monomer, 15-55 part dispersion agent, 30-85 part inorganic salt, 230-500 part deionized water.
Aqueous dispersion type recovers the oil by a preparation method for amendment, and the method comprises the following steps:
30-85 part inorganic salt are dissolved in 230-500 part deionized water and make the aqueous solution, add 15-55 part dispersion agent to stir, 70-150 part acrylamide, add 5-10 part anionic monomer, add 5-10 part cationic monomer, 1-5 part hydrophobic monomer, after stirring, proceed in reactor, be warming up to 30 ℃, logical nitrogen 30min adds 1# initiator 0.03-0.05 part, continue logical nitrogen 10min and add 2# initiator 0.01-0.025 part, logical nitrogen 10min adds 3# initiator 0.01-0.025 part, be warming up to 50 ℃, stop logical nitrogen, isothermal reaction 12 hours, obtain finished product.
Further, described 1# initiator is any in Diisopropyl azodicarboxylate, 2,2'-Azobis(2,4-dimethylvaleronitrile), azo diisobutyl amidine hydrochloride.
Further, described 2# initiator is any in ammonium persulphate, Potassium Persulphate, Sodium Persulfate, hydrogen peroxide.
Further, described 3# initiator is any in sodium bisulfite, Sulfothiorine, trolamine, rongalite.
Further, described anionic monomer is any in vinylformic acid, methacrylic acid, fluorine-containing methacrylic acid, siliceous methacrylic acid, methylene-succinic acid, 2-acrylamide-2-methylpro panesulfonic acid, sodium allyl sulfonate; Described cationic monomer is any in dimethyl [2-(methacryloxy) ethyl] [3-(trimethoxy silicon propyl group] ammonium chloride, 2-(methacryloxypropyl) ethyl-trimethyl salmiac, dimethyl diallyl ammonium chloride, MethacryloyloxyethylTrimethyl Trimethyl Ammonium Chloride, acrylyl oxy-ethyl-trimethyl salmiac.
Further, described hydrophobic monomer is any in vinyltriethoxysilane, vinyltrimethoxy silane.
Further, described inorganic salt are any in ammonium sulfate, magnesium sulfate, sodium sulfate, sodium-chlor, Repone K, magnesium chloride.Described dispersion agent is any in dextrin, beta-cyclodextrin.
The present invention contrasts prior art, has following beneficial effect: product adopts water bag aqueous dispersion polymerization, and product is instant, reduces the curing time of dosing time and conventional polyacrylamide solution; On conventional gel basis, introduce positively charged ion chain link, make to produce firmly absorption between gel molecular and electronegative rock, increase the resistance to flow of water, improve the flushing resistance of gel; Initial viscosity is lower, and pumping into property is good, and construction technology is simple, little to environmental injury; Biologically stable is good, and profile control validity period is more than half a year; Product is water-in-water emulsion polymerization, instant in use procedure.
Accompanying drawing explanation:
Fig. 1 is that aqueous dispersion type recovers the oil with preparation method's schema of amendment.
