FIELD: oil-and-gas production.
SUBSTANCE: device for surveying of high-temperature wells contains vessel Dewar bottle, plug, heat absorber and chassis with electronic circuit. Heat absorber is implemented in the form of cup with openings in bottom and cover of cup. Internal volume of cup is filled by material with low temperature of melting and high specific heat of fusion. Inside the cup there are installed bushings of diametre equal to internal diametre of cup. Bushings allow openings equal to number of conductors, passed through opening sin parallel to each other. In spaces between the first bushing and bottom of cup and between the second bushing and cover of cup there are located layers of thermal-resistant encapsulating composition.
EFFECT: increasing of protection of electronic circuit of device against coming of heat by conductors and reliability of operation of well device in high-temperature wells.
