FIELD: well spectrometry.
SUBSTANCE: in accordance to the invention, an emitter of ultraviolet radiation irradiates the fluid, which, in turn, fluoresces. Fluorescence radiation is transferred to photo-detector with several channels and then - to optical spectrometer. By matching fluorescence maximum wave length and brightness of fluorescent luminescence of sample being analyzed, density of fluid is determined in degrees of American Petrol Institute (API). By tracking change of ratio of fluid sample fluorescence intensity in blue and green areas of spectrum during reduction of pressure active on the fluid, pressure of creation of pyrobitumen deposits is determined.
EFFECT: simple and reliable devices for fluorescent spectrometry under conditions of a drilled well.
