Description
Technical field
The present invention relates to a kind of ternary oil displacement Produced Liquid demulsifier.
Background technology
Demulsifier in the market has certain effect for the oil-water emulsion of routine, but is produced for ternary oil displacement
Almost without too big effect, and dosage is very big, processing cost is also very high for the demulsification and water-oil separating of the oil emulsion of liquid.Daqing oil field
Designing institute has carried out the tackling of key scientific and technical problems up to the more than ten years to this problem, at present also without any important breakthrough.Petrochina is surveyed
The experiment for visiting institute have also appeared production accident, and chemical feeding quantity tried entirely from 6ppm to 50ppm, and profit does not separate not only, also results in
Rp-emulsification, produce oil-containing in water and be up to 7 ten thousand to 8 ten thousand ppm, pollute whole water treatment system, thousands of mouthfuls of pressure gauges necrosis and
Water injection well is blocked.
The content of the invention
It is an object of the invention to provide a kind of de-emulsification speed is fast, oil-water separation is good, safety and environmental protection ternary oil displacement
Produced Liquid demulsifier.
Ternary oil displacement Produced Liquid demulsifier of the present invention, its preparation method are as follows：
1) raw material prepares：
Percentage by weight is 10 --- 13% phenol-formaldehyde resin modified, the phenol-formaldehyde resin modified are in the big of phenolic resin
Alkyl chain is introduced on strand,
Percentage by weight is 17 --- 19% maleic anhydride-epoxy propane copolymer,
Percentage by weight is 4.5 --- 6% PPG,
Percentage by weight is 1.8 --- 4.5% ethylene glycol monobutyl ether,
Surplus is the aromatic solvent of safe environment protection type；
2) 7/3/10ths to 20 aromatic solvent is added in blending tank, is then turned on stirring dress
Put；
3) all phenol-formaldehyde resin modifieds are added in blending tank, continue to stir, be completely dissolved it；
4) it the maleic anhydride-epoxy propane copolymer will all add in blending tank, and continue to stir, and make it completely molten
Solution；
5) PPG is added in blending tank, continues to stir, while keep in tank temperature more than 15 DEG C；
6) all ethylene glycol monobutyl ethers are added, continue to stir；
7) the remaining aromatic solvent is added in tank, continues stirring 25 --- 35 minutes, produce ternary oil displacement extraction
Liquid demulsifier.
Ternary oil displacement Produced Liquid demulsifier of the present invention, the raw material prepare as follows：
Percentage by weight is 11.2 --- 12% phenol-formaldehyde resin modified,
Percentage by weight is 17.8 --- 18.5% maleic anhydride-epoxy propane copolymer,
Percentage by weight is 4.8 --- 5.5% PPG,
Percentage by weight is 2 --- 3% ethylene glycol monobutyl ether,
Surplus is the aromatic solvent of safe environment protection type；
Temperature is 20 in the middle holding tank of the step 5) --- and 30 DEG C.
Ternary oil displacement Produced Liquid demulsifier of the present invention, 1/3rd aromatic solvent is added in the step 2)
In blending tank.
Ternary oil displacement Produced Liquid demulsifier of the present invention, component modification phenolic resin have very strong lipophile, oil-soluble
Fabulous, diffusion velocity is very fast in oil, the oil-water interfaces of oil emulsion can be moved within the most short time and play demulsification
Effect.Good lipophilic group expoxy propane, hydrolyzed maleic anhydride also have fine hydrophilic radical in component epoxy propane polymer
Maleic anhydride, therefore in addition to demulsification, moreover it is possible to the trickle oil particles being dispersed in water are linked together, become big
Oil droplet, oil is set to be separated from the water out as early as possible.Component PPG is mainly used in strengthening oil-water separation, after making separation
Oil-containing is preferably minimized in water.Component ethylene glycol monobutyl ether is mainly to improve the dissolving effect of each component in a solvent as stabilizer
Fruit, density and pH value are adjusted, ensures the steady in a long-term of product, it is not sunk to the bottom, it is not stratified.Component aromatic solvent flash-point is taken the photograph 68
More than family name's degree, it is not inflammable and explosive dangerous material, is largely insoluble in water, so water pollution will not be caused.So ternary of the present invention is driven
Oily Produced Liquid demulsifier has the advantages of good water quality of de-emulsification speed soon, after separation, safety and environmental protection, and due to being oil-soluble production
Product, played a role from oil phase side, compared with water-soluble products in the market, dosage is small；And due to being oil-soluble production
Product, rest on always in oil, second emulsifying can be prevented, water quality will not also be adversely affected.
The embodiment of the present invention is described in further detail below；Following examples are used to illustrate the present invention,
But it is not limited to the scope of the present invention.
