Abstract
A downhole tool can include a connector welded to a housing, and a sensor element in compression between the connector and the housing. A method of measuring a load applied to a downhole tool can include positioning a sensor element between a connector and a housing, then applying a compressive force to the sensor element, then securing the connector to the housing, thereby maintaining the compressive force in the sensor element, and then deploying the downhole tool into a subterranean well. A wireline cable head can include a weak link that parts at a predetermined tension level applied to the cable head, a connector secured to the weak link and to a housing, and a sensor element in compression between the connector and the housing.
Claims22
A wireline cable head for use in a subterranean well, the wireline cable head comprising:
- a weak link configured to part at a predetermined tension level applied to the cable head;
- a connector secured to the weak link and to a housing configured for attachment to a bottom hole assembly;
- and
- a sensor element in compression between the connector and the housing.
