[0040] The utility model will be further described below in combination with the drawings.

[0041] In the process of oil drilling construction, the existence of oil and gas needs to be judged by using the fluorescence of oil, and the content and nature of oil and gas are qualitatively identified. Oil will emit a special 'light' under ultraviolet irradiation, and the emission phenomenon disappears when the irradiation stops. This property is called the fluorescence of oil. The fluorescence of oil is related to the content of each component in oil, and different components have different fluorescence color tones. The oil quality is light blue or milky white, the gum is yellow, and the asphalt is brown yellow or brown. As long as the core, rock and mud contain one hundred thousandth of oil or asphalt, there will be a display under the fluorescence detection device.

[0042] Fluorescent detection devices typically place rock samples in a separate operating box and illuminate them with a fluorescent lamp. The operator then observes the samples directly through an observation port. However, the observation ports of existing fluorescent detection devices are generally open, and the volatilization of sulfides, hydrocarbons, and halogenated hydrocarbons added to enhance the observation effect in the rocks can easily be inhaled by the operator, affecting their health. In addition, fluorescent detection devices can only perform single-point fluorescence examination, making it difficult to conduct direct multi-point fluorescence comparison.
