METHOD AND DEVICE FOR MAGNETIC INDICATED TRACING OF OIL DEPOSITS Russian patent published in 2009 - IPC E21B47/00 G01N24/08 

FIELD: mining.

SUBSTANCE: according to invention marked fluid on water or oil base containing water and/or oil indicators-tracers is pumped into payout bed; after bed filtration of marked fluid concentration of tracers is assessed on surface samples of products of producing wells by means of nuclear magnetic resonance. Also water solutions of non-organic salts of metals and/or deuterium are used as marking substance of marked fluid on water base, and fluocarbon compounds and/or metal-organic complexes are used as marking substances of marked fluid on oil base. To increase accuracy, responsiveness, and efficiency of invention implementation the operations of setting, measurement, processing, registration of nuclear magnetic resonance characteristics and assessment of contents of indicators-tracers in bed fluid are performed automatically by means of a special device on base of pulse apparatus of nuclear magnetic resonance in single process cycle and system sequence.

EFFECT: increased information value and efficiency of control over development of oil deposit.
