As a large industrial system, petroleum industry is mainly composed of geological exploration, drilling, logging, geological logging, oil testing, oil production (gas), underground operation, oil and gas gathering and processing, storage and transportation and oilfield engineering construction. Due to the special type of petroleum industry, it is easy to cause fire, explosion and other security risks in the process of processing and storage in oil depots. The main risk factors of fire and explosion accidents are flammable and explosive gases formed by oil leakage. In the presence of ignition sources such as open flame, electric spark, electrostatic spark, impact spark and lightning or high temperature, the leaked oil volatilizes to form oil and gas to ignite and burn, which leads to fire. When the mixture of oil and gas and air reaches a certain concentration, it forms an explosive mixture, which will explode when it meets the ignition source; Petroleum products themselves have certain toxicity, and a large number of leaks and unreasonable discharges will cause poisoning and public hazards such as people and animals. Therefore, advanced technology and high-tech monitoring means are adopted to realize the fire prevention and explosion prevention safety of the petroleum industry. Reducing accident losses by * * * * * is the development trend of fire prevention monitoring and management in the process of oil production, transportation and storage.

Petroleum science and technology workers have been exploring in petrochemical production safety, security monitoring and other aspects, expecting to find an efficient means of prevention and monitoring. Infrared thermal imaging technology uses non-contact method to detect, and intuitively reflects the working state of the equipment through the temperature distribution on the surface of the equipment, which not only does not interfere with production, but also can control the running state of the equipment in time.

At present, a considerable number of petrochemical enterprises have used infrared thermal imaging technology to carry out preventive testing on common equipment in petrochemical industry, such as boilers, electrics, transmissions, pipelines, valves and so on.
