Abstract
A wireline apparatus comprises a sheave for accommodating a wireline and a sheave mounting configured for coupling to a wireline stuffing box. The apparatus includes a sensor for measuring at least one of wireline tension and deployed wireline length at the sheave.
Claims59
A wireline sheave apparatus comprising:
- a sheave for accommodating a wireline;
- a sheave mounting configured for coupling to a wireline stuffing box, the sheave being mounted on the sheave mounting;
- and
- a sensor for measuring wireline tension,
- wherein the sheave mounting comprises a frame which includes a first frame part and a second frame part, the first and second frame parts being arranged such that tension on the wireless tends to cause the first and second frame parts to pivot relative to one another;
- and
- wherein the sensor is provided between the first and second frame parts so as to measure parameters indicative of forces acting on the wireline.

A wireline work method comprising:
- mounting a sheave on a sheave mounting comprising a frame which includes a first frame part and a second frame part, the first and second frame parts being arranged such that tension on the wireless tends to cause the first and second frame parts to pivot relative to one another;
- coupling the sheave mounting to a wireline stuffing box;
- passing wireline around the sheave;
- providing a sensor between the first and second frame parts;
- and
- using the sensor to measure parameters indicative of forces acting on the wireline.

A wireline sheave apparatus comprising:
- a sheave for accommodating a wireline;
- a sheave mounting configured for coupling to a wireline stuffing box, the sheave being mounted on the sheave mounting;
- and
- a sensor for measuring at least one of wireline tension and deployed wireline length at the sheave;
- wherein the sheave is frame-mounted on a sheave mounting frame;
- wherein the sheave mounting frame provides mounting for the sensor;
- wherein the sensor comprises a strain gauge which is mounted on the frame and is configurable to measure wireless tension;
- and
- wherein parts of the frame are arranged to pivot relative to one another and tension on the wireline tends to cause the parts to pivot, such that a strain gauge on a load pin preventing the parts from pivoting indicates wireline tension.
