Abstract
The invention provides a hydrophobic association type oil-displacing agent. The hydrophobic association type oil-displacing agent comprises raw material monomers, a mixed solvent, a stabilizer and an initiator; the raw material monomers are acrylamide (AM), stearyl methacrylate (SMA) and petroleum sodium sulfonate and sodium p-styrenesulfonate (SSS); the mixed solvent is N,N-dimethylformamide (DMF) and ethanol; the stabilizer is polyvinylpyrrolidone (PVP); and the initiator is azobisisobutyronitrile (AIBN). According to the hydrophobic association type oil-displacing agent, the hydrophobic groups in the molecules are aggregated due to the association action; and when the polymer concentration in the oil-displacing agent is relatively low or exceeds the minimum concentration limitation, the hydrophobic groups on different molecular chains are in good contact with each other to interact to form an effectively three-dimensional structure, and consequently, the whole aqueous solution is formed into a net, the viscosity of the solution becomes great and the purpose of effectively reducing the oil-water mobility ratio is achieved. Meanwhile, excellent temperature resistance and salt resistance also are achieved.
Description
Technical field
The present invention relates to a kind of oil-displacing agent, belong to technical field of petroleum extraction.
Background technology
Hydrophobic associated polymer refers to the polymkeric substance of the molecular structure hydrophilic macromolecular chain with a small amount of hydrophobic grouping.In chemical agent for oil recovery, normally on the basis of the polyacrylamide driven as general polymer, the monomer having hydrophobic structure by other carries out polymerization and obtains.Aqueous solution characteristic and the general polymerization thing aqueous solution characteristic of this polymkeric substance make a big difference.Hydrophobic associated polymer in aqueous, is assembled because heat resistance and salt tolerance produces between its hydrophobic grouping.The ultimate principle that polymer flooding improves oil recovery factor improves oil displacement efficiency, and realize mainly through absorption, viscous effect, at these on, the viscosity of polymers soln is a very important index.Flooding polymers AP-P4 is acrylamide, vinylformic acid, alkyl dimethyl allyl ammonium chloride multipolymer, molecular weight 1.7 × 10
6, degree of hydrolysis is 18.2%, hydrophobic group content < 1%, for the one of such hydrophobic associated polymer, be widely used in domestic each elephant at present, but there is stability problem in applying at the scene, easily to degrade, cause viscosity loss.At high temperature, polymers soln because the reason such as oxygenizement, heat collapse makes viscosity reduce, thus can lose use value.
Summary of the invention
The present invention is the deficiency overcoming above-mentioned technology, provides a kind of terpolymer hydrophobic association type oil-displacing agent.
The technical solution used in the present invention:
A kind of hydrophobic association type oil-displacing agent, comprise starting monomer, mixed solvent, stablizer and initiator, described starting monomer is acrylamide (AM), stearyl methacrylate (SMA), petroleum sodium sulfonate and Sodium styrene sulfonate (SSS), described mixed solvent is N, dinethylformamide (DMF) and ethanol, described stablizer is polyvinylpyrrolidone (PVP), and described initiator is different fix one's eyes upon (AIBN) of azo two.
Described mixture DMF DMF and the volume ratio of ethanol are 1:1.5.
The percentage composition that described stearyl methacrylate (SMA) accounts for gross weight is 4% ~ 6%.
The percentage composition that described petroleum sodium sulfonate and Sodium styrene sulfonate (SSS) account for gross weight is 4.5% ~ 5.5%.
The percentage composition that described stablizer polyvinylpyrrolidone (PVP) accounts for gross weight is 3.5% ~ 4.5%.
The percentage composition that described initiator azo two different fix one's eyes upon (AIBN) accounts for gross weight is 0.65% ~ 0.75%.
Beneficial effect of the present invention: hydrophobic association type oil-displacing agent of the present invention, assemble because association produces between hydrophobic grouping in molecule, when oil-displacing agent interpolymer concentration is lower reach or exceed minimum concentration restriction time, hydrophobic grouping on differing molecular chain can well contact and produce the effective three-dimensional structure of formation that interacts, the whole aqueous solution being forms one and throws the net, viscosity becomes very large, plays the object effectively reducing oil and water mobility ratio.Meanwhile, also there is good temperature resistant antisalt performance.
