Description
Technical field
The present invention relates to reducing thick oil viscosity fields, and in particular to a kind of low-temperature eutectic species heavy crude thinner, a kind of viscous crude drop
Application of the stick in high gum asphaltic content reducing thick oil viscosity.
Background technique
Petroleum is one of widest natural resources of human use, is the heterogeneous mixture of a variety of organic compounds, point
Son amount differs greatly.Petroleum is the indispensable valuable source in the world today, for communications and transportation, industry manufacture and daily life
Every aspect, petrochemical industry is the important component of a National Industrial.Global Oil explored secrets accretion of stock 150 in 2016
Hundred million barrels, reach 1.7 trillion barrels.From the point of view of reserve distribution, OPEC tissue occupies the petroleum reserves in the whole world 71.6%, rather than OPEC
National oil reserves only account for 28.4%, and the regional disparity of reserves is fairly obvious.The average petroleum consumption in the whole world in 2016 reaches
96550000 barrels/day, wherein U.S.'s consumption figure is sure to occupy the whole world first, reaches 19,630,000 barrels/day；Consumption of China amount occupies second, reaches
To 12,380,000 barrels/day.With current world petroleum demand level calculation, existing proved reserves can also continue exploitation about 50 years.But it is complete
Ball oil demand is growing steadily, by the promotion of the emerging markets energy-consuming such as India and China, it is contemplated that the following 10 years world
Oil demand will increase 20-25%.
American Petroleum Institute (API) is classified crude oil, and the crude oil by API severe greater than 31.1 ° is defined as lightweight
Oil, API severe be defined as between 22.3 ° and 31.3 ° in matter oil, the API severe of viscous crude is between 10 ° and 22.3 °, super-viscous oil
The API severe of (pitch) is less than 10 °.API index is higher, and oil quality is higher, and commercial value is bigger.
Viscous crude is the non-conventional oil resource having a extensive future, China's heavy oil reserves account for verify total crude oil reserve three/
One.The outstanding feature of viscous crude is high viscosity, needs that it is extracted on the ground and carried out from reservoir using additional complexity technique
Long-distance transportation.The mining method of viscous crude is broadly divided into thermal method and non-thermal method at present.Thermal method includes that reservoir burns, cyclic steam gulps down
The technologies such as Tuhe steam assisted gravity drive.Non- thermal method includes mixing the technologies such as dilute viscosity reduction, chemical viscosity reduction and reducing viscosity by emulsifying.Although thermal method
It is highly effective, but need to expend a large amount of energy and be related to the process matched therewith expenditure of great number.Non-thermal method such as mixes dilute method, though not
It is energy-intensive, but a large amount of diluent is needed to can be only achieved the viscosity that normal exploitation needs, has seriously affected its economy.
Reducing viscosity by emulsifying, which exists, brings difficult negative effect and waste water handling problem to back segment multi-purpose station breaking emulsion and dewatering, fails at the scene
Obtain large-scale promotion application.Existing chemical viscosity reduction method has certain viscosity reducing effect to viscous crude but that there are viscosity break ratios is low, environment is dirty
Dye, the problems such as bio-toxicity is high.The development of oil-soluble viscosity reducer is the research hotspot of reducing thick oil viscosity, but meets the oil of industrial requirements
The rare report of dissolubility thinner.
CN 101007939A proposes that a kind of solvent naphtha ratio reaches the heavy crude thinner of 50%-90%, containing aromatic hydrocarbons,
Heterocyclic and diesel oil.Such thinner dosage is big, viscosity reduction low efficiency, less economical.CN 101245240A, which is proposed, a kind of uses third
The advanced ester of olefin(e) acid and methacrylate with hydroxyl cause viscous crude drop polymerize with dodecyl benzene sulfonic acid blend
Stick, the pipeline viscosity reduction for viscous crude.Such thinner introduces amphipathic functional group and polar group to enhance wax
Repulsion between matter and asphaltene molecules breaks structure and viscosity is reduced, improves anti-deposit.But essentially, viscosity reduction
Agent belongs to pour point depression dosage form, and the viscous crude low to paraffin content does not have effect.The shortcomings that in order to avoid the above all kinds of thinners, seek performance
More excellent while less side effects heavy crude thinner, people start to be conceived to some other types of chemical substances, and visit
Study carefully its possibility as heavy crude thinner.
Summary of the invention
The technical problem to be solved by the present invention is to how to overcome the shortcomings of the prior art, provide that a kind of dosage is few, nothing
Toxicity and the good low-temperature eutectic species heavy crude thinner of viscosity-reducing performance.
The technical solution of the invention is as follows: a kind of low-temperature eutectic species heavy crude thinner, ion composition are as follows:
It further comprise a kind of preparation method of low-temperature eutectic species heavy crude thinner, by choline chloride and 3- phenylpropyl alcohol
Sour heating stirring synthesis.
Further, the choline chloride and 3- benzenpropanoic acid molar ratio are 1:2.
Further, a kind of low-temperature eutectic species heavy crude thinner by the choline chloride and 3- benzenpropanoic acid 80~
1~3h of agitating and heating in 100 DEG C of oil baths, until the transparent liquid of reaction mixture.
Further, the application including a kind of low-temperature eutectic species heavy crude thinner as heavy crude thinner.
Low-temperature eutectic species heavy crude thinner in the present invention, with other surfactants common in the market, polymer, oil
Dissolubility thinner is compared, and low in raw material price, synthetic operation is simple, environmental-friendly nontoxicity, break gum asphalt structure,
Reduce viscosity of thickened oil, increase viscous crude mobility in terms of all have remarkable result, under the high temperature conditions still with splendid Viscosity-reducing
Energy.The present invention is worth with market potential.
