STUDING THE POSSIBILITIES OF PHOSPHORS USING IN TRACER STUDIES OF OIL WELLS

Andrei Tiutiaev, Georgy Mozgovoy, Evgeny Biktimirkin

Abstract

When developing oil fields, water flooding is often used to displace oil. In this case, effective oil production is possible with a detailed study of hydrodynamics in the reservoir. Recently, organic phosphors have been used for these purposes, which are pumped into the formation through injection wells. The spectral characteristics of the excitation (absorption) and luminescence of produced water with phosphors can provide information on the hydrodynamic relationship between injection and producing wells and the efficiency of field development. A technique has been developed for measuring the spectral characteristics of the excitation and luminescence of plate water based on a spectrofluorimeter. The methodology 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.). Two-dimensional scanning is also possible to obtain three-dimensional patterns of excitation and luminescence. The methodology gives recommendations on the choice of spectral ranges, receiver sensitivity, number of averaging points, scan step, etc.
