Effect test

Embodiment 1

[0122] Add 1-methylnaphthalene to the heavy oil produced or / and exported to reduce the viscosity of the heavy oil, thereby reducing the flow resistance of the heavy oil and making the heavy oil flow smoothly;

[0123] Test shows: described 1-methyl naphthalene is added in heavy oil, can effectively reduce heavy oil viscosity (referring to the experimental data of experimental result table 3.);

Embodiment 2

[0125] Repeat embodiment 1, difference is only: in order to prevent described 1-methylnaphthalene from producing crystal, solid matter or solidification in low temperature environment, add fusel oil in the described 1-methylnaphthalene;

[0126] The fusel oil refers to any one of the by-product fusel oil from fermentation alcohol production, the by-product fusel oil of butadiene produced by alcohol method, or a mixture of them in any proportion;

[0127] Any one of the fusel oils is a commodity or can be purchased from the market;

[0128] The added fusel oil ensures that the 1-methylnaphthalene is always liquid in a low temperature environment without producing crystals, solids or solidification.

Embodiment 3

[0130] Repeat embodiment 1, the difference is only: in order to prevent described 1-methylnaphthalene from producing crystals, solids or solidification in a low-temperature environment, add a special organic solvent in the described 1-methylnaphthalene;

[0131] The special organic solvent refers to any alcohol in alcohols (such as octanol, isoamyl alcohol, etc.), glycol derivatives (such as ethylene glycol butyl ether, diethylene glycol butyl ether, diethylene glycol ethyl ether, etc.) One or a mixture of any two or more of them in any proportion;

[0132] Any one of the above-mentioned special organic solvents belongs to commodity or can be purchased from the market;

[0133] The added special organic solvent ensures that the 1-methylnaphthalene is always in a liquid state in a low-temperature environment without producing crystals, solids or solidification.

Abstract

The invention discloses application of methylnaphthalene in lowering viscosity of thickened oil, which comprises application of 1-methylnaphthalene in lowering viscosity of thickened oil and the specific implementation steps, 2-methylnaphthalene in lowering viscosity of thickened oil and the specific implementation steps and mixed methylnaphthalene in lowering viscosity of thickened oil and the specific implementation steps. The invention enlarges the application method of methylnaphthalene, clearly demonstrates the specific application method of using methylnaphthalene to lower viscosity of thickened oil, solves the problems of great load and power consumption, frequent machinery accidents, high surface line return pressure, and the like of an oil extractor during extracting and outwards transporting thickened oil in the background art, and can effectively lower viscosity of thickened oil and reduce extraction and outward transportation cost of thickened oil.

Description

technical field [0001] The invention relates to the application field of methylnaphthalene, in particular to the application of methylnaphthalene in reducing the viscosity of heavy oil. Background technique [0002] The current public information shows that methylnaphthalene is mainly used to produce disperse dye auxiliary (dispersant), and can also be used as heat carrier and solvent, surfactant, sulfur extractant, and can also be used to produce plasticizer and fiber dyeing aid , It can also be used to determine the standard fuel of alkane number and cetane number. [0003] "Oilfield Chemistry" page 175 penultimate 5-6 lines of "Oilfield Chemistry" printed for the first time in the first edition in July 2000 by China University of Petroleum Press stated, "Because the oil is thick, the load of the pumping unit is large, and the power consumption is large. Frequent mechanical accidents and high back pressure of surface pipelines bring difficulties to the extraction and tran...
