| Abstract | The possibilities of utilization of electric probes developed for oil research in geothermal well logging are limited by high temperatures. The paper identifies two types of limits and the ways of overcoming them. A few solutions are presented and some of the probes constructed are shortly described. for the electric probes (as well as for the cable of connection with surface) seems to be, however, 400?C. of optical transducers and es permitting temperatures up to 500?C. The maximum ization temperature To overcome this limit, use is proposed |
