Description
Technical field
The invention discloses a kind of preparation method for low concentration wax Wax removing agent, belong to oil field chemical technology of preparing
Field.
Background technology
Paraffin generally exists with liquid under formation conditions.But crude oil is in recovery process, with temperature and pressure
Decline and the continuous effusion of light components, the molten wax ability of crude oil constantly reduce, paraffin starts to crystallize, separates out, assembles, blocking
Oil reservoir and sleeve pipe or surface duct and equipment.In fact, the wax born during oil extraction is not pure wax, it is former
Those in oil mix with high-carbon n-alkane, both containing other higher hydrocarbons, again containing asphalitine, colloid, silt particle, iron
The semisolid and solid matter of rust, inorganic scale and oil-water emulsion etc..
It is a kind of relatively more extensive Paraffin Removal technology of current field use to carry out Paraffin Removal to oil well with chemical agent, and this is
Because carrying out Paraffin Removal with chemical agent, typically medicament is added from annular space, does not influence the normal production of oil well and other
Operation, in addition to it can receive wax removal wax control result, pour point depression, viscosity reduction and the effect of de-plugging can also be received using some medicaments
Fruit.General chemical Paraffin Removal is based on two kinds of mechanism first, being that can form one layer in metal surface using one or more medicaments
Polar Crystal Slab is to influence the wetability of metal surface, so as to reduce the deposition of wax.Second, it is to add one or more medicaments to change it
Become wax-crystal structure or make wax is brilliant to be in dispersity, it is mutually not superimposed each other, so as to be suspended among crude oil.This kind of material is exactly
Usually said wax crystal modifier and wax crystal dispersing agent.Wax-proofing agent is developed based on above-mentioned principle.The work of paraffin remover
With process be by the wax deposited dissolve or scatter, make its in oil well crude oil in dissolving or little particle suspended state and with
Oil well liquid stream effluent oil well, this such as is related to permeating, dissolve and disperse at process.Its mechanism of action is according to different paraffin remover types
Can be different.In recent years, as the extensive use of surfactant, solvent-borne type Wax removing agent have tremendous development, summarized
To be broadly divided into oil base Wax removing agent, water based dewaxing agent and emulsion-type Wax removing agent three types.But existing Paraffin Removal
During, it is poor to the removal effect of low concentration or fraction wax, simultaneously because dilution of the Wax removing agent of addition through oil, leads
Cause wax control result poor, thus for it is current the problem of research and develop a kind of efficient Wax removing agent be key prepared by the present invention.
The content of the invention
Present invention mainly solves technical problem：For removal of the existing Wax removing agent to low concentration or fraction wax
Effect is poor, simultaneously because dilution of the Wax removing agent of addition through oil, the problem of causing wax control result poor, there is provided Yi Zhongyong
In the preparation method of low concentration wax Wax removing agent.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）In mass ratio 1:10, aluminum nitrate is added in deionized water, simultaneously heating water bath is stirred, ammonia spirit is added dropwise
To pH to 8.5, insulation reaction obtains mixed base body fluid；
（2）In mass ratio 1:5, oleic acid is added dropwise in mixed base body fluid, it is still aging and centrifuge after being added dropwise to complete,
Collect lower sediment and wash, obtain washing precipitate；
（3）In mass ratio 1:10, washing precipitate and hydrochloric acid are stirred, heating water bath obtains gel modification liquid, by weight
Number meter, weighs 45~50 parts of deionized waters, 10~15 parts of ethylene glycol monobutyl ether solution and 10~15 parts of gel modification liquids, stirs respectively
Mixing and stewing process are mixed, obtains aqueous phase；
（4）Count in parts by weight again, weigh 10~15 parts of hexamethylenes, 15~20 parts of petroleum ethers and 15~20 parts of dimethylbenzene respectively and put
In beaker, it is stirred and stands, obtain oil phase；
（5）In mass ratio 1:8:8, Tween-80, oil phase and aqueous phase are stirred, heating water bath and isothermal holding, ultrasonic disperse
Afterwards, stand and be cooled to room temperature, you can be prepared into one kind and be used for low concentration wax Wax removing agent.
Step（1）Described ammonia spirit is the ammonia spirit of mass fraction 15%.
Step（2）Described oleic acid drop rate is 2mL/min.
Step（3）Described concentration of hydrochloric acid is 0.3mol/L.
Step（3）Described ethylene glycol monobutyl ether solution is the ethylene glycol monobutyl ether solution of mass fraction 2%.
The beneficial effects of the invention are as follows：
（1）The present invention by petroleum ether, dimethylbenzene etc. is used as oil phase, due to small side chain or not branched small organic molecule then
It is easily accessible in wax, reaches the purpose of fast instant wax, oil phase is effectively dissolved wax, simultaneously because phenyl ring can be used as crystalline substance
Core, before the nucleus of paraffin separates out, it is largely separated out, wax crystal is effectively improved oil phase to wax with dispersity
Solubility property；
（2）The present invention improves the oleophylic performance of material, coagulant liquid is effectively wrapped wax by oleic acid modified gel liquid
Wrap up in, simultaneously because gel aluminum hydroxide can be effectively increased the total concentration of emulsion ion, improve Wax removing agent oil resistant dilution properties, together
When to electrically charged micelle create attract oppositely charged ion advantage, reduce and neutralize the electricity of small molecule wax
Lotus, it is lost holding stable condition, after making its polymerization of reuniting, wrapped up by oil phase, so as to effectively remove low concentration wax.
