Abstract
A stuffing box assembly for a wellhead intervention has a stuffing box and an adjustable sheave. The stuffing box has a body with a collar for connecting to a wellhead and with a passage for running wireline therethrough. A frame connected to the body has side plates and has a hub assembly with hubs rotatable about a first rotational axis. An axle interconnects the two hubs and supports them between the side plates. The sheave can rotate about the second rotational axis of the axel to run the wireline into and out of the stuffing box. The hub assembly can be rotated about its axis of rotation to adjust the location of the axle's axis of rotation. This can move the sheave away from a fixed guard, can change how the sheave lines up with the stuffing box, and can move the sheave away from the stuffing box.
