USE OF COMPOSITES WITH ADJUSTED NANOTUBES FOR HEAT TRANSMISSION IN WELLS Russian patent published in 2014 - IPC F28F21/02 B81B1/00 E21B12/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to heat engineering and can be used for heat removal from heating units in wells. In the device containing an anisotropic nanocomposite element which is bounded thermally with a heating unit for the purpose of heat removal from the above unit along the preset direction, the anisotropic nanocomposite element forms a cable and includes heat-conducting nanoparticles introduced into the base material and adjusted in it in order to form a heat line to transmit heat from the first cable end to its second end, at that the heat conductivity in the preset direction is bigger than the heat conductivity in the direction perpendicular to the preset direction and the base material is configured so that there is contact between the heat-generating and heat-absorbing elements. The invention also includes the method of heat removal and the tool intended for use in the well.

EFFECT: improving operational efficiency of the downhole tool.
