Abstract

The invention relates to the technical field of photochemical detection and analysis, and discloses a fluorescent compound used for oil flooding viscosity detection in tertiary oil recovery, a preparation method and application thereof. The fluorescent probe is 2-(4-(bis(4-methoxyphenyl)amino)phenyl)anthracene-9,10-dione (TPAMD). The probe compound of the present invention is composed of groups with aggregation-induced luminescent properties and anthraquinone groups with electron-withdrawing effects, and simultaneously have aggregation-induced luminescent properties and intramolecular charge transfer properties. The probe is easy to prepare, has a high yield, has a good response to viscosity, and has a good linear response. At the same time, it can cope with complex solvent environments and has good resistance to solvent interference. It can detect the viscosity of chemical displacement agents in the oil recovery field. , has the potential for analytical detection in many viscosity-sensitive fields such as chemistry, food, and the environment.

Description

technical field

[0001] The invention relates to the technical field of photochemical detection and analysis, in particular to a fluorescent compound used for oil flooding viscosity detection in tertiary oil recovery and its preparation method and application. Background technique

[0002] Petroleum, a viscous dark brown liquid, is known as "the blood of industry" and "flowing gold". Through later refining, countless downstream commodities can be obtained to support the development of modern civilization. Chemical industry, energy, textile, pharmaceutical and many other fields have varying degrees of field control power, and it is also an important non-renewable strategic energy source. In order to alleviate the direct and sharp contradiction between unlimited development and limited resources, increasing the oil recovery rate is the only way. After the primary oil recovery stage that depends on the eruption of formation pressure and the secondary oil recovery stage that inj...
