Abstract
The invention provides an oil-soluble identification agent. The oil-soluble identification agent is prepared by mixing, by mass, 0.01-3% of benzodifuran (C12H8O), 20-50% of Sudan blue, 30-50% of Sudan yellow, and 20-50% of xylene (C8H10), and the sum of mass percentages of above components is 100%. The oil-soluble identification agent can be used for identifying the quality of the fuel oil and the fuel oil additives. The oil-soluble identification agent allows a detection method to be simple, has high stability, and has no influences on the physical and chemical indexes of the fuel oil and the additives.
Description
Technical field
The present invention relates to a kind of oil-soluble markers for identifying fuel oil or fuel oil additive and application thereof.
Background technology
Fuel oil and additive product thereof need meet as some technical specification such as volatility or octane value; the height of product quality is difficult to be judged by naked eyes; and the quality of fuel qualities cannot be judged at the scene; some are wished to obtain the manufacturer of high profit, often can by dilution high-quality product or counterfeit high-quality product trade mark to obtain more interests.Substituting this product, or carry out managing very difficult with the behavior that the product of inferior quality mixes quality product, and key ingredient in high-quality product its content is very low usually so that use quantitative test detect whether through dilution be also very difficult.
The application principle of markers is oil field tracer technique, and it is called as tracer agent in this field, and the object using tracer agent is to describe oil reservoir qualitatively.The technology starting stage mainly uses radiotracer.In recent years along with the fast development of computing machine, facilitate the progress of tracer technique, develop various chemical tracer.
Chemical tracer mainly comprises following a few class:
(1) inorganic salts of Yi Rong.As SCN
-, NO
3 -, Br
-, I
-, Cl
-deng, be mainly used as water tracer.Due to sandstone formation surface band negative electricity. this kind of tracer agent is few in surface of stratum absorption. and consumption is little. and the photometer measuring method that is easily split detects.
(2) fluorescent dye.The anionic dyes such as picture famille rose, sodium alizarinsulfonate, eosin W or W S, can provide organic anion to be used as water tracer.But due to large in surface of stratum adsorbance. some compositions in stratum also can interference analysis, so the residence time just can not use more than 5 days in the earth formation.Short owing to asking during stop in crack. adsorption loss is few. may be used for the crack detecting well formation.
(3) alcohol of halogenated hydrocarbons and low relative molecular mass.Halogenated hydrocarbons, as fluoro trichloromethane, triclene, dibromopropane, phenyl-hexafluoride etc., can be used as oily tracer agent and gaseous tracer.They are few in surface of stratum adsorbance, and easily for vapor-phase chromatography detects, but impact is had on the aft-loaded airfoil of crude oil.Low mass molecule alcohol such as picture methyl alcohol, ethanol, n-propanol, isopropyl alcohol, butanols, amylalcohol etc., multiplexly makes water tracer and profit distributes tracer agent.This kind of tracer agent biological stability is poor. all need adding of germicide when throwing in and sample. and to prevent from causing concentration change because of biodegradation.
