OSTI ID:6165919
A wireline guide for use in oil-well industry has three arms, each of which is made of parallel elongated trusses with support plates attached between the trusses. The first, lower arm is fixedly attached at 45/sup 0/ angle to a collar of a pack-off assembly, the second arm is swivelly attached at its lower end at 45/sup 0/ angle to the upper portion of the first arm, the second hand having a first pulley wheel rotatably mounted between the trusses at the upper portion of the second arm. A bumper is integrally mounted to the upper portion of the second arm in order to prevent contact between a traveling block and the wireline. The lowermost pair of support plates attached to the swivel arm are mounted at 45/sup 0/ angle in relation to the trusses. A third, removable arm is mounted at its lower end between the angular support plates and extends vertically upwardly from the second arm. The uppermost reinforcing plates of the third arm are mounted at 45/sup 0/ angle to the trusses, one of which has a diagonal wireline slot. A second pulley wheel is mounted atop the third arm between the trusses. The second arm can be swivelled 180/sup 0/ outwardly from the pack-off assembly when wireline operations are not in progress.
