ABSTRACT:
Measuring operations can for example be carried out in wells (1) where the progress of an intervention tool (3) is difficult (deflected wells for example) by means of a tubing (2), a support frame (5) linked with the tool and which can be anchored in the lower end part of the tubing, an electric-carrying cable (12) unwound from a surface installation and fitted with a connector (9, 11) that can plug into the support frame in a wet medium after the tool has been taken down into the well, in order to tightly link the tool to the cable. The base of the tubing is fitted with a piping end (18) allowing the support frame to come out of it. With this device, the tool can be driven to the intervention zone by exerting a thrust on the tubing and, once the connector is in place, the tubing can be totally taken away from this zone and continuous measurings can be carried out by traction on the cable.
