Description
Technical field：
The invention belongs to oil field chemical technical field, and in particular to a kind of preparation method of crude oil thinner.
Background technology：
At present, with the increase of world's crude oil demand amount, the exploitation of conventional crude cannot meet the need of production development
Ask, produce needs to be continuously increased the yield of viscous crude to fill up the notch between demand.High solidifying height in oil reservoir is found out in China
Viscous crude oil reserve enriches, but exploits difficulty of transportation, the reason is that a variety of containing paraffin, resin and asphalt etc. in crude oil
The mixture of complicated hydro carbons, due to the presence of paraffin, resin and asphalt in crude oil so that this kind of oil density is big, solidification point
Height, viscosity are big, flow difficulties, and this situation seriously constrains viscous crude and crude oil production conveying.
The flowing of crude oil is related with crude oil solidification point, viscosity of crude.Due to the generally existing of wax in crude oil, in oil extraction
As temperature constantly declines in course of conveying, wax partial crystallization goes out mutual aggregation in crude oil, and crude oil fluidity declines, so as to cause to convey
Difficulty, general viscosity of crude is in below 1000mpa.s, favourable flow.To improve the mobility of waxy crude oil, take very much
Kind of carrying method, including be heat-treated, add drag reducer, dilution etc., but these methods there are energy consumption is big, administration fee is high and stopping transportation after
The problems such as restarting difficulty.Common method is mainly in heavy oil gathering both at home and abroad at present:Heating, Emulsifying, mix
Water or active water law, mixing light oil method etc..But efficiency is highest to belong to chemical viscosity reduction method.However, there are kind for existing thinner
Less, dosage is big, of high cost, and the technical problem such as new type thinner exploitation difficulty.
The content of the invention：
The present invention is made up and improved in place of above-mentioned the deficiencies in the prior art, there is provided and a kind of technique is simple, easy to operate,
Product is stablized, and securely and reliably, there is stronger low temperature viscosity reduction and demulsification to complicated ingredient viscous crude, and does not influence crude oil abjection
Water quality, and dosage is few, and cost is low, toxic side effect is small.
The technical solution adopted by the present invention is：A kind of preparation method of crude oil thinner, its preparation method are：To equipped with
228 grams of bisphenol-As and 2.3 grams of potassium hydroxide are added in the reaction kettle of blender, kettle cover and the bolt that screws up with a wrench is closed, will react
Kettle vacuumizes, and inflated with nitrogen vacuumizes, when vacuum reaches 0.03kPa, by the temperature in reaction kettle again to 0.2 MPa
120 DEG C are risen to, and starts to be passed through 300 ~ 400 grams of ethylene oxide into reaction kettle, controlling reaction temperature is led at 120 ~ 130 DEG C
After entering ethylene oxide, when constant temperature 2 is small in reaction kettle, reaction kettle is opened when reaction kettle is cooled to 50 ~ 55 DEG C, to reaction kettle
1500 ~ 2000 grams of deionized water is added in interior product, 119 ~ 130 grams of sodium chloroacetates is added and stirs, by reaction kettle
Temperature rise to 85 DEG C after constant temperature 4 ~ 6 it is small when, when the temperature in reaction kettle is down to 40 ~ 45 DEG C, into reaction kettle add 58 ~ 81
Gram sodium sulfate of polyethenoxy ether of fatty alcohol, discharge after stirring evenly, obtain crude oil thinner.
The sodium sulfate of polyethenoxy ether of fatty alcohol is 12 ~ 18 sodium sulfate of polyethenoxy ether of fatty alcohol of carbochain.
Beneficial effects of the present invention：Compared with prior art, the present invention is simple with technique, easy to operate, and product is stablized,
Securely and reliably, there are stronger low temperature viscosity reduction and demulsification to complicated ingredient viscous crude, and do not influence crude oil abjection water quality, and
The advantages that dosage is few, and cost is low, toxic side effect is small, positive effect.
