INVESTIGATION METHOD OF HYDROCARBON DEPOSITS Russian patent published in 2016 - IPC E21B47/11 E21B47/07 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry and can be used in development of oil deposits by thermal methods, particularly in organization of in-situ combustion (HSV). This method is realized by pumping to injection well together with expelling and/or oxygen-containing agent of tracer agent which changes chemical formula at required temperature, but keeps safe tracer properties and recordings of concentration of initial and transformed tracer agents in producing wells. For this purpose, at least one tracer agent is pumped at least in one injection well, which changes the chemical formula at required temperature, but retains tracer properties and registers concentration of initial and transformed tracer agents separately at least in one production well. After that, according to the ratio of initial and transformed tracer agents in well production temperature and dimensions of the zone of thermal effect or combustion are estimated.

EFFECT: increase of information about studied object of development, determination of temperature in the zone of thermal action,particularly in combustion zone at HSV to optimize the mode of injection of the oxidant and/or heat carrier and/or displacing agent into layer.
