The paper shows the possibility of using luminophores to identify liquid flows in the rock. The spectral characteristics of the excitation (absorption) and luminescence of produced water with a phosphor can provide information on the hydrodynamic relationship between injection and production wells and on the efficiency of field development. A method for measuring the spectral characteristics of excitation and luminescence of water based on a spectrofluorimeter has been developed. The technique includes primary visual control and sampling, simultaneous scanning with two monochromators, measurement and analysis of the excitation (absorption) spectrum, mathematical operations with graphs to determine the luminescence parameters (Stokes shift, relative flux, etc.). 2D scanning is also possible to obtain 3D excitation and luminescence patterns. The technique gives recommendations on the choice of spectral ranges, receiver sensitivity, number of averaging points, scanning step, etc. [ABSTRACT FROM AUTHOR] |
