FIELD: oil production, particularly thermal field investigation inside producing wells.
SUBSTANCE: method involves lowering downhole cable provided with temperature meter in well, wherein downhole cable is arranged outside production string. Fluid temperature is measured by means of downhole measuring-and-stabilizing unit including at least one temperature sensor and parameter stabilizing device. The temperature sensor is installed so that sensing member thereof touches production string wall or production string clutch wall or is located in immediate proximity thereto. Crystal resonators are used as the temperature sensors. Land-based measuring assembly includes frequency electronic measuring module. The land-based measuring assembly and conductive signal transmitting communication line thereof with measuring-and-stabilizing unit may simultaneously read signals from all temperature sensors if number of temperature sensors exceeds 1.
EFFECT: increased measuring accuracy in working well in initial and following time periods and possibility of method usage in wells with any oil recovery mechanism.
