WELL TEMPERATURE MEASUREMENT DEVICE Russian patent published in 2010 - IPC E21B47/06 

FIELD: oil-and-gas industry.

SUBSTANCE: invention related to oil-and-gas industry, notably to wells boring and particularly to geophysical research, assigned for well temperature measurements during the boring process. A device for well temperature measurement contains a case, a fluid oscillator with system of nozzles, a surface, panel, commutation channels, a receiver tank, a power source, a transductor, a sylphon, a hydraulic actuator operation rod, connected to network channel. The power source executed as a balloon with compressed gas. The fluid oscillator inlet nozzle installed in the panel with a gap, executed as a flexible one and equipped with a bimetallic plate stiffly fixed on it. One of the bimetallic plate ends stiffly fixed in the panel, other one is free and movable. EFFECT: well temperature measurements during boring process reliability and accuracy increase.
