Method for determining thermal conductivity of soil layers along vertical borehole, involves carrying out determination of thermal conductivity of each soil layer at each remote drilling tool by measuring device in partial manner
摘要
<p>The method involves carrying out a determination of the thermal conductivity of each soil layer at each remote drilling tool by a measuring device in a partial manner. The measuring device embedded in a borehole (9). A temporary heat-conductive contact is produced between the measuring device and the borehole wall. An independent claim is also included for an apparatus determining the thermal conductivity of soil layers along a vertical bore.</p>
