FIELD: oil and gas industry.
SUBSTANCE: invention relates to geophysical engineering, in particular for the oil and gas industry. Complex device for the study of high-temperature wells contains a main body with sensors of gamma-ray, coupler locator, pressure and temperature sensor placed sequentially from top to bottom with a working range up to +175 °C, as well as the lower body, connected to the main body by a high-temperature geophysical cable, with a temperature sensor located in it with a working range of up to +300 °C.
EFFECT: invention can be used to study oil and gas wells and allows to ensure the reliability of the measuring instruments of standard temperature performance in high-temperature wells, due to the possibility of controlling the temperature in the zone of location of devices with a sharp increase in temperature in the zone of injection of fuel and oxidizing composition into the reservoir.
