Wireline winch mounting system

Claim 1

In an apparatus for running wireline tools in well conduit with a power driven drum, the improvement comprising: a tubular member having mounting means for securing to the top of the well conduit and having a passage extending therethrough for the passage of wireline; a sheave mounted adjacent the top of the tubular member for guiding wireline into the passage; frame means for mounting the drum on a side of the tubular member with its axis perpendicular to the axis of the well conduit and below the sheave for reeving the wireline from the drum through the sheave; and a cylindrical lift sub secured to the frame means and having a collar means for engagement by a set of elevators to lift the well conduit with drilling rig blocks by using the tubular member, frame means and lift sub as a link between the blocks and the well conduit.

Claim 3

An apparatus for running wireline tools in a well conduit, comprising in combination: a tubular member having a passage therethrough for receiving the wireline and a lower end for securing to the top of well conduit; a sheave mounted adjacent the top of the tubular member for guiding the wireline; and frame means for mounting a drum on a side of the tubular member for support by the tubular member, the wireline being wound around the drum and reeved through the sheave; a hydraulic motor mounted to the frame means and connected to the drum for rotating the drum; and hydraulic power means located in a remote unit for supplying pressurized hydraulic fluid through a hose to the hydraulic motor.

Claim 4

An apparatus for running wireline tools in a well conduit, comprising in combination: a tubular member having a passage therethrough for receiving the wireline and a lower end for securing to the top of well conduit; a sheave mounted adjacent the top of the tubular member for guiding the wireline; and frame means for mounting a drum on a side of the tubular member for support by the tubular member, the wireline being wound around the drum and reeved through the sheave; a hydraulic motor mounted to the frame means and connected to the drum for rotating the drum; and hydraulic power means located in a remote unit for supplying pressurized hydraulic fluid through a hose to the hydraulic motor.

Claim 7

An apparatus for running a wireline tool in well conduit, comprising in combination: a frame; a drum wound with wireline and rotatably mounted to the frame with its axis of rotation perpendicular to the axis of the well conduit; a hydraulic motor mounted to the frame and connected to the drum for rotating the drum; hydraulic power means located in a remote unit for supplying pressurized hydraulic fluid through a hose to the hydraulic motor; a tubular member mounted to the frame and having a lower end for connection to the well conduit; a sheave carried by the frame adjacent the top of the tubular member, over which the wireline from the drum is reeved; wireline sealing means carried by the tubular member of a type that utilizes pressurized viscous fluid to seal the wireline against pressure in a well conduit; air pressure means remotely located for supplying pressure to the viscous fluid in the wireline sealing means; wireline packoff means mounted to the tubular member for selectively forming a static seal about the wireline when the wireline is not moving; the wireline packoff means being actuated by hydraulic fluid pressure supplied from the hydraulic power means; and a cylindrical lift sub mounted to the frame above the top of the tubular member and having an annular collar for engagement by elevators of a drilling rig; the frame, tubular member and lifting sub forming a load-bearing link between the elevators and the well conduit to allow the well conduit to be lifted with drilling rig blocks.

Claim 8

An apparatus for running a wireline tool in well conduit, comprising in combination: a frame; a drum wound with wireline and rotatably mounted to the frame with its axis of rotation perpendicular to the axis of the well conduit; a hydraulic motor mounted to the frame and connected to the drum for rotating the drum; hydraulic power means located in a remote unit for supplying pressurized hydraulic fluid through a hose to the hydraulic motor; a tubular member mounted to the frame and having a lower end for connection to the well conduit; a sheave carried by the frame adjacent the top of the tubular member, over which the wireline from the drum is reeved; wireline sealing means carried by the tubular member of a type that utilizes pressurized viscous fluid to seal the wireline against pressure in a well conduit; air pressure means remotely located for supplying pressure to the viscous fluid in the wireline sealing means; wireline packoff means mounted to the tubular member for selectively forming a static seal about the wireline when the wireline is not moving; the wireline packoff means being actuated by hydraulic fluid pressure supplied from the hydraulic power means; and a cylindrical lift sub mounted to the frame above the top of the tubular member and having an annular collar for engagement by elevators of a drilling rig; the frame, tubular member and lifting sub forming a load-bearing link between the elevators and the well conduit to allow the well conduit to be lifted with drilling rig blocks.
