ABSTRACT:
A well tool such as a measuring sonde is arranged in a protective housing and introduced into a well at the end of a tubing. A retractable latching device fastens the tool to the housing and to an electrical transmission cable. The tubing is connected with a pumping assembly capable of circulating up to the housing a cooling fluid at a temperature lower than the temperature prevailing in the well and the tool is operated by moving the tool out of the housing and by bringing the tool regularly back into the housing, which is permanently cooled by the fluid.
