CONNECTING HEAD FOR CONNECTING A CABLE AND A DOWNHOLE TOOL AND ASSOCIATED INTERVENTION DEVICE.

摘要

The head (80) comprises an upper portion for attaching and connecting to a cable (32) and a lower attaching portion for electrically connecting to a control and transmission module (82) of a tool to be lowered in the well. The head (80) comprises a hollow outer enclosure (94) and a mechanical connection assembly. The mechanical connection assembly comprises an attaching member (114) and a liner (116) defining an inner lumen (121 ) to receive the attaching member (114) and the lower end of the cable (32) The connecting head (80) defines a first downhole electrical path (70) able to extend from a lower segment (126) of the cable to a first connector of the control and transmission module (82), the first downhole electrical path (70) being completely electrically insulated from the outer enclosure (94).
