Description
Technical field
The present invention relates to a kind of terpolymer, a kind of preparation method of polymkeric substance and the polymkeric substance being prepared by the method, and described terpolymer and polymkeric substance are as the application of described polymer oil-displacing agent.
Background technology
Oil field generally enters today of high water-cut development period at home, polymer flooding taking high molecular partially hydrolyzed polyacrylamide (HPAM) as main representative improves oil recovery factor technology and becomes effective day, and is used widely in one, two class oil reservoirs of low temperature, less salt.But for the formation condition feature of high temperature, high salt in three class oil reservoirs, high molecular partially hydrolyzed polyacrylamide (HPAM) exists that salt tolerance is poor, facile hydrolysis, easily degraded, easily generate the problems such as precipitation with the divalent-metal ion complexing such as calcium, magnesium, and its actual oil displacement efficiency in three class oil reservoirs is significantly declined.
At present for the oil reservoir resource (formation temperature 70-95 DEG C, stratum salinity 10000-30000mg/L) of three class formation conditions, in worldwide, still do not have ripe, industrialization, commercial polymer oil-displacing agent product to come out.In order to address the above problem, improve three class oil recoveries, the oil-displacing agent of research and development adaptation high temperature, high salt formation condition has become the major fields of industry member, academia's research and development.
At present, adopt temperature resistant antisalt monomer, as 2-acrylamide-2-methylpro panesulfonic acid (AMPS), NVP (NVP) or N, N-DMAA (DMAM) has improved polyacrylamide temperature resistant antisalt performance to a certain extent with acrylamide copolymerization, but still cannot meet the requirement of three class oil reservoirs completely, there is following shortcoming mainly due to aforesaid propylene amides copolymer: 1., owing to being difficult to prepare the copolymer that relative molecular mass is higher, the apparent viscosity of its solution under high temperature and high salt formation condition is not high; 2. because above-mentioned functions monomer and acrylamide activity differ larger, in multipolymer, the content of functional monomer is not high, and its heat-resistant stability and salt tolerance need further to be improved; 3. in the time injecting well head, anti-high speed shear performance is needed raising badly; 4. dissolution time needs to shorten.
As CN1240797A discloses the preparation method of a kind of sulfonated monomers and acrylamide copolymer: add acrylamide and sulfonated monomers in reaction vessel, fully stir monomer is dissolved completely, add redox initiation system, polymerization temperature is controlled at 15-30 DEG C, obtain sulfonated monomers and acrylamide copolymer, molecular weight is 1 × 10
6-1 × 10
7product has good use properties, and its temperature resistant antisalt has had improvement to a certain degree compared with polyacrylamide, but relative molecular mass and apparent viscosity still need further raising, its anti-high speed shear performance, anti-absorption property are needed raising badly, and its dissolution time needs a step to shorten.
Sclerotium gum (Scleroglucan), xanthan gum (Xanthan gum, XG) are all polyphosphazene polymer polysaccharide, are to integrate thickening, suspension, emulsification, stabilization, the xanthan gum that performance is comparatively superior.Compared with HPAM, Sclerotium gum and xanthan gum, because of its unique polysaccharide structures unit having, make it use and have the following advantages as oil-displacing agent: its solution still has high viscosity number under high temperature, high salinity condition; Anti-mechanical shearing ability is strong; Short and the solution of dissolution time is difficult for by reservoir rock absorption etc.But how polysaccharide structures unit is introduced and is still a still open question.
Use for reference the constructional feature of the poly-polysaccharide such as Sclerotium gum and xanthan gum, by the polymerisable monomer with glycosyl units by the method for terpolymer, be incorporated on the macromolecular chain of monomer (AMPS/NVP/DMAM) of acrylamide, above-mentioned temperature resistant antisalt performance, in keeping the excellent viscoelasticity of linear macromolecule, can improve the apparent viscosity under the warm high salt geologic condition of height, improve anti-shear performance and the anti-rock absorption property of its solution, can further improve the recovery ratio of three class oil reservoirs.
Document (Properties of Biomedical Pressure-Sensitive Adhesive CopolymerFilms with Pendant Monosaccharides, J Appl Polym Sci, 1995, 56:1615) report a kind of preparation method of butyl acrylate-methacrylic acid glucosyloxy ethyl ester multipolymer: in glass test tube, add a certain amount of dimethyl sulfoxide (DMSO), butyl acrylate, methacrylic acid glucosyloxy ethyl ester, Diisopropyl azodicarboxylate, logical nitrogen deoxygenation, at 70 DEG C, react 12 hours, by product water/acetone precipitation, obtain butyl acrylate-methacrylic acid glucosyloxy ethyl ester multipolymer, but butyl acrylate-methacrylic acid glucosyloxy ethyl ester multipolymer is water-soluble very poor, cannot use as Flooding Agent for EOR.
Summary of the invention
The object of the invention is to overcome the defect of above-mentioned prior art, provide high, the heat-resisting and good salt tolerance of a kind of molecular weight superelevation, apparent viscosity, anti-high-shear performance good, polymkeric substance that good water solubility and dissolution time are short and its preparation method and application.
