Abstract
An apparatus for collecting fluids dispersed from a wireline as the wireline is guided over a pulley. Two housing halves are hinged together at one end so that they may be opened and closed to form a chamber between the housing halves. In the open position, the housing halves are placed around a stuffing box, packing nut and wireline pulley and are then closed and latched so as to surround the stuffing box, packing nut, wireline pulley and portion of the wireline engaged with the pulley. When in their closed position, the chamber seals around the stuffing box at the lower portion of the chamber to prevent leakage of collected fluid. A bearing horizontally mounted within the chamber engages with the packing nut and a shaft rotatably mounted in the housing provides for external adjustment of the packing nut around the wireline.
Claims11
A well fluid collector, comprising:
- a. a housing having walls defining a chamber adapted to enclose a wireline pulley and collect fluids dispersed from a wireline engaged with said pulley;
- b. means for removably mounting said housing around a wireline pulley;
- c. means for allowing passage of a wireline engaged upon said pulley through said chamber;
- d. means for preventing leakage of collected fluid from said chamber;
- and
- e. means external of said chamber, for adjusting a packing nut enclosed by said chamber.
The apparatus of claim 3, wherein said means for preventing leakage from said chamber comprises raised edges adjacent said apertures.
A well fluid collector, comprising:
- a. a first housing half;
- b. a second housing half hingedly engaged with said first housing half;
- c. means mounted on said first and second housing halves for latching said first and second housing halves in a closed position, said first and second halves having walls defining a chamber adapted to enclose a wireline pulley and collect fluids dispersed from a wireline engaged with said pulley;
- d. means for allowing passage of a wireline engaged upon said pulley through said chamber;
- e. means for preventing leakage of collected fluid from said chamber;
- f. means for draining said collected fluid from said chamber;
- g. means for swivel engagement of said housing halves with a stuffing box, said chamber surrounding a packing nut mounted on top of said stuffing box;
- and
- h. means for adjustment of said packing nut when said halves are in said closed position.
