APPARATUS FOR PRODUCING GEOPHYSICAL MEASUREMENTS IN A BOREHOLE |
| 摘要 |
<p>AN APPARATUS FOR PRODUCING GEOPHYSICAL MEASUREMENTS IN A BOREHOLE. A measuring tool for producing geophysical measurements within a borehole comprises a crawler belt, at least a portion of which constitutes a support for a transducer. The crawler belt is continuously displaced within the bore hole by means of a suspension cable and guide pulley in cooperating relation with spiked shoes and retaining plates for maintaining at least the transducer-supporting portion of the crawler belt in a stationary position with respect to the borehole wall during each measurement stage.
