METHOD OF INVESTIGATION OF MASSIVE FRACTURED OIL DEPOSITS INTERNAL STRUCTURE Russian patent published in 2017 - IPC E21B47/00 G06F17/50 E21B49/00 

FIELD: oil and gas industry.

SUBSTANCE: method of determining the internal structure of massive fractured oil deposits, comprising a preliminary determination of reference temperature log and subsequent sequential conduction of well field research on stationary filtering modes, conduction of field downhole research with measuring the temperature, pressure and borehole flowrate with obtaining actual temperature log, comparison actual temperature log with the reference one, identification by comparing abnormal temperature profiles of well, and determination of allowable range of possible parameter values for each fracture, intersecting a borehole, from the condition of minimum deviation values of calculated and actual temperature log parameters with predetermined trust level.

EFFECT: creation of method for studying the internal structure of massive fractured oil deposits, which provides reception of additional data on fractures crossing the borehole, in particular, more reliable data on the length, slope, width and fracture opening.
