Petroleum fluorescence collecting and analyzing method based on charge coupled element optical fiber system

The invention relates to a petroleum fluorescence collecting and analyzing method based on a charge coupled element optical fiber system. According to the method, a charge coupled element photoelectric detector is utilized to carry out fluorescence detection; a charge coupled element array in the charge coupled element photoelectric detector can be used for collecting wavelength-light strength corresponding data only by carrying out photon integration without grating rotation beam split, so that the entire analysis period is shortened; the analysis period is 155 seconds; and the production efficiency of an oil field is improved; the entire analysis system is small in size, light in weight, convenient for operation and strong in impact resistance, and is suitable for severe analysis environment without a lab-level severe analysis environment condition; an optical fiber is used as a transmission channel of a light path system, so that the traditional lens type symmetrical light path can be replaced; and the size and the weight of the entire analysis system can be reduced while the environmental suitability of the system is improved, so that the integrally-formed optical system is more suitable for the more narrower using condition of the oil field in situ and a condition that an instrument generally needs to be transported.
