Description
Technical field
The present invention relates to a kind of preparation method of efficiently paraffin remover, belong to paraffin remover preparing technical field.
Background technology
All contain certain wax in crude oil, wax generally exists with dissolved state in the earth formation.However, in oil extraction process
In, temperature and pressure constantly reduces, and when temperature and pressure is reduced to a certain numerical value, the wax dissolved in crude oil just starts to analyse
Go out.With pressure, the continuous spilling for continuing reduction and light components of temperature, the wax in crude oil just constantly separates out, and crystallizes, be long
Greatly, assemble, and deposited on sucker rod surface and tube inner wall.
The paraffin deposited in oil well pipe and ground gathering line can cause the reduction of pipeline net sectional area or even block,
Pump efficiency is caused to decline, oilwell produced fluid amount decline, sucker rod can fracture because of overload (uplink load and friction in down stroke increase), oil well
The problems such as back pressure raises and thus causes the increasing of oil pumper power consumption and fault rate to rise.Paraffin deposit problem is opened as oil
Adopt, collect defeated during a major issue.The whole world economic loss caused by paraffin deposit and sinks for paraffin every year
Product controls costly up to tens dollars.To ensure oil extraction and collecting defeated to be smoothed out, the oil well of wax deposition need to be carried out clearly
Wax control.For oil field Paraffin Removal mainly based on wax removal, supplemented by wax control, the method for cleaning wax deposition mainly has mechanical treatment process, deep fat
Or steam hot wash method.
It is the more extensive method of current field use chemically to carry out wax removal and wax control to oil well.Generally by medicament
Add or added by hollow rod from oil jacket annular space, do not interfere with the normal production and other operations of oil well.Except can be with
Play outside Paraffin Removal effect, can also play a part of pour point depression, viscosity reduction, de-plugging using some medicaments.Chemical clear, paraffin remover has oil
Three kinds of dissolubility, water solubility and emulsion-type liquid are clear, paraffin remover, in addition with a kind of solid paraffin remover.
But the speed of paraffin dissolution to be present unhappy for currently used oil-soluble paraffin remover, the defects of causing molten wax effect difference, therefore
Invent a kind of efficiently Wax dissolving agent has positive meaning to oil field wax removal technical field.
The content of the invention
Present invention mainly solves technical problem, oil-soluble paraffin remover the speed of paraffin dissolution is unhappy during for current oil extraction
A kind of defect, there is provided preparation method of efficiently paraffin remover.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:
A kind of preparation method of efficiently paraffin remover, it is characterised in that specifically preparation process is:
(1)600~800g lemons are weighed, are squeezed the juice to obtain lemon juice with juice extractor, lemon juice is added in beaker, are added into beaker
Enter 300~400g lime stone, heat temperature raising, after reaction, filter off while hot except filtrate obtains filter residue;
(2)Filter residue is placed in beaker at normal temperatures, 300~400mL concentrated sulfuric acid solutions are slowly added to along beaker wall of cup, is stirred
Afterwards, 400~500mL sodium chloride solutions are added to beaker, mixed liquor is obtained after stirring;
(3)Oil phase is obtained after toluene is mixed with benzene, according to the mass fraction, 13~15 parts of distillations are added into high speed dispersor
Water, 10~20 portions of mixed liquors, 50~55 parts of oil phases, after disperseing, obtain pre-dispersed liquid;
(4)Acetone and n-hexane are mixed to get intermixture, weigh 200~300g palm oils, add 300 into palm oil~
400mL intermixtures, stirring, obtain premixing palm oil, premix palm oil is fitted into beaker, stirred crystallization, after vacuum filtration, gone
Except filtrate is crystallized, good oil is obtained after being cooled to room temperature;
(5)Count in parts by weight, 10~15 parts of dodecyl sodium sulfates are added into pre-dispersed liquid, then dripped with constant pressure funnel
Add 40~50 parts of good oils, stir, until solution is transparent, after insulation, standing obtains efficient paraffin remover.
Step(1)The described time of squeezing the juice is 30~40min, and temperature is 80~90 DEG C after heat temperature raising, the reaction time 1
~2h.
Step(2)The mass fraction of the described concentrated sulfuric acid be 75%, add concentrated sulfuric acid solution after mixing time be 10~
15min, sodium chloride solution mass fraction are 45%, and mixing time is 3~4min.
Step(3)Described toluene and the mixing quality ratio of benzene are 5 ︰ 1, and high speed dispersor rotating speed is 2000~3000r/
Min, jitter time are 3~4h.
Step(4)Described acetone and the mixing quality ratio of n-hexane are 2 ︰ 1, and mixing time is 5~10min, at beaker
In under the conditions of 0 DEG C of ice-water bath, the stirred crystallization time is 20~30min, and vacuum filtration temperature is 0 DEG C, is filtered by vacuum the time
For 30~40min.
Step(5)The drop rate of described constant pressure funnel is 5~10mL/min, and speed of agitator is 200~300r/
Min, mixing time are 10~20min, and temperature is 70~80 DEG C during insulation, and soaking time is 2~3h.
The beneficial effects of the invention are as follows:
(1)Mixed solution in the present invention in the pre-dispersed liquid of efficient paraffin remover is rich in citrate, the organic group of citrate
Group can be dispersed in oil phase well, and because its molecular weight is larger, citrate can increase microemulsion density, improve note
Enter efficiency, and Water-In-Oil, oil-in-water emulsion are more stablized, be unfavorable for profit phase separation, in addition simple grain Water-In-Oil point
Son or oil-in-water molecule can be adsorbed in faster oily wax surface further permeate, wettability reversal so that peeling rate is accelerated, increase
The speed of paraffin dissolution, so as to reach the purpose of efficient molten wax;
(2)Palm oil after the purification that the present invention adds is similar to the organo moiety of wax, and both compatibilities are preferable, adding
After paraffin remover, palm oil spreads intrusion wax layer by the mixing oil phase of toluene and benzene, and crystallization is easily formed under water cladding so that
Wax layer packing of molecules structure is destroyed, and rapid deterioration is simultaneously dispersed into small pieces, accelerates molten wax effect, so as to reach the effect of efficient molten wax
Fruit.
