INVESTIGATION METHOD OF HYDROCARBON DEPOSITS Russian patent published in 2016 - IPC E21B47/06 E21B47/11 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry and can be used in developing an oil deposit by thermal methods, in particular when providing in-situ combustion (ISC). Method involves pumping into at least one injection well together with the uploaded agent of a mixture of at least two tracer agents of different heat resistance in the required ratio and concentration. Then recording the concentration of each tracer agent in at least one production well. After that by the change of proportions (relative ratios) of the tracer agents in the wells product relative to their proportions in the injected mixture a temperature and dimensions of the zone of thermal effect or combustion are evaluated.

EFFECT: technical result is increased information value of the analyzed object of development, determination of temperature in the zone of thermal effect, in particular, in the combustion zone at ISC for optimizing the mode of an oxidizer and/or a heat carrier and/or a displacement agent uploading into the bed.
