| 摘要 |
The disclosure relates to a device for measuring resistivity to be mounted on a downhole tool and comprising:
- a watertight body,
- a first electrode and a second electrode electrically insulated from the first electrode and surrounding the first electrode, arranged in the body at a proximal end of the device,
- an electrical connecting module arranged in the body and comprising a first contacting element electrically coupled to the first electrode and a second contacting element electrically coupled to the second electrode, surrounding the first contacting element, with interposition of an electrically insulating material between the first and second contacting element;
wherein the electrical connecting module projects from the body at a distal end of the device so as to form an electrical interface. |
