The embodiment of the invention discloses a fluorescence detection method and device and computer equipment, and belongs to the field of oil and gas exploration and development. The method comprises the following steps: acquiring a fluorescence spectrum of a sample, wherein the fluorescence spectrum comprises fluorescence intensities corresponding to any excitation wavelength and any emission wavelength, wherein the excitation wavelength is the wavelength of ultraviolet light irradiating the sample, the emission wavelength is the wavelength of fluorescence emitted by the sample after being irradiated by the ultraviolet light, and the fluorescence intensity is the intensity of fluorescence emitted by the sample after being irradiated by the ultraviolet light; according to a plurality of preset wavelength ranges, dividing the fluorescence spectrum into a plurality of areas, wherein the wavelength ranges comprise at least one of an excitation wavelength range and an emission wavelength range; and counting the fluorescence intensity in each region to obtain an oil-gas index, and determining the fluid type of the sample according to the oil-gas index. According to the invention, the fluorescence detection efficiency and the accuracy of a detection result can be improved.
Description
technical field [0001] The embodiments of the present application relate to the field of oil and gas exploration and development, and in particular to a fluorescence detection method, device and computer equipment. Background technique [0002] In the field of oil and gas exploration and development, fluorescence detection technology is an important means to detect oil and gas content. Fluorescence detection technology refers to the technology of using ultraviolet light to irradiate oil-containing samples and observing the fluorescence emitted by the samples to determine the oil content of the samples. At present, the operator usually observes the fluorescence emitted by the sample with the naked eye or uses a microscope to observe the fluorescence emitted by the sample, but this method has high requirements for the operator, will consume a lot of labor costs, and the detection efficiency is low.
