Process for preparation is：First, by oleic acid base hydroxyethyl imidazole quinoline, dodecyl benzyl dimethyl ammonium chloride, four ethene
Five three kinds of raw materials of amine polyoxyethylene polyoxypropylene ether are proportionally added into normal pressure enamel reaction still, stir 25 minutes, are slowly warming up to
50 DEG C, 1-hydroxy ethylidene-1,1-diphosphonic acid, ethylene glycol are proportionally added into while stirring, are continued stirring 25 minutes, are then proportionally added into ammonia
The methylenephosphonic acid of base three, ethylenediamine tetra-acetic acid, it is sufficiently stirred 25 minutes, continues to be proportionally added into fluorocarbon surfactant FN-3, no
After disconnected stirring 25 minutes, stop heating.Cool down while stir, be cooled to normal temperature.Water is proportionally added into, it is stirring while adding,
Stirring discharges after 20 minutes, obtains a kind of oil recovery corrosion-release scale-proof wax-removal agent.
Using effect：The oil well 63-38x corrosion and scaling phenomenons in the first oil recovery factory of North China Oilfield Yan Ling work areas are serious, and companion
There is slight wax deposition, tried out using the present invention in the well, solve the problems, such as the corrosion and scaling wax deposition of oil well.
With reference to SYT 5273-2000《Oil field extracted water corrosion inhibiter method of evaluating performance》Standard, surveyed using static corrosion
Determine method, take the recovered water of wild goose 63-38x wells, tested using N80 steel standard test piece at 80 DEG C, research corrosion and inhibition
Effect, data such as table 7 is obtained after standing 7 days.
Confirmatory experiment data of the medicament of table 7 to wild goose 63-38x well corrosion inhibitions
As can be seen from the data in the table, to wild goose 63-38x wells, average corrosion rate is reduced by the 0.0220mm/a before dosing
0.0031mm/a after to dosing, corrosion inhibition rate are about 85.7%, illustrate that medicament meets the requirement of the well inhibition.
With reference to SYT 5673-93《Scale inhibitor for oilfield Reliable Evaluating Methods of Their Performance》Standard, the recovered water of wild goose 63-38x wells is taken to enter
Row experiment, studies fouling and scale inhibition effect, data such as table 8 is obtained in laboratory.
Confirmatory experiment data of the medicament of table 8 to wild goose 63-38x well scale effects
As can be seen from the data in the table, to wild goose 63-38x wells, scale inhibition performance 92.0%, illustrate that medicament meets the well scale inhibition
Requirement.
Before dosing, oil pumper up stroke electric current has built up 48A, and after dosing, oil pumper up stroke electric current gradually decreases to
40.3A, 16.1% is have dropped, show that medicament meets the requirement of the well wax removal viscosity reduction, and positive effect.
In summary, a kind of recover the oil that the present embodiment provides uses corrosion-release scale-proof wax-removal agent, has both met oil well wild goose 63-38x
Requirement to corrosion-mitigation scale-inhibition, the requirement to wax removal viscosity reduction is met again, corrosion inhibition rate up to 85.7%, up to 92.0% pump by scale inhibition performance
Machine up stroke electric current declines 16.1%.
The stability test of embodiment 5
Stability is examined or check with corrosion-release scale-proof wax-removal agent with oil recovery prepared by embodiment 2.
Oil recovery corrosion-release scale-proof wax-removal agent prepared by embodiment 2 is in yellow after just preparing, and clear.In room
Temperature, dry, it is shady and cool under conditions of place longer period of time (such as one month) after, solution is still in yellow, and clear.By its
In the first oil recovery factory of North China Oilfield, Yan Ling work areas 63-69x wells are tried out, and corrosion inhibition rate is up to 87.5%, and scale inhibition performance is up to 93.5%, oil pumper
Up stroke electric current declines 15.0%.This is basically identical with the using effect after just preparing, and meets wild goose 63-69x and inhibition is hindered
The requirement of dirty wax removal, illustrate that a kind of stability of oil recovery corrosion-release scale-proof wax-removal agent provided by the invention is good.
Comparative example
Using existing patent document as foundation, a kind of oil recovery of the similar present invention of investigation is steady with the medicament of corrosion-release scale-proof wax-removal agent
It is qualitative.
2- alkyl -1- ethoxy -3- hydroxypropyl imidazoline sodium phosphates:8% (8g)；Dodecyl dimethyl Benzylmagnesium chloride
Amine:12% (12g)；FC-N01 fluorocarbon surfactants：0.1% (0.1g)；Alkylphenol-polyethenoxy (14) ether：5% (5g)；First
Aldehyde：4.5% (4.5g)；Hexa：10% (10g)；Calgon：6% (6g)；1-hydroxy ethylidene-1,1-diphosphonic acid：6%
