摘要： There is provided a sealing assembly for a bearing assembly that supports a rotating tubing string that extends through the riser. The sealing assembly has a plurality of sealing elements. Each sealing element has a seal body having an inner sealing surface designed to seal against a tubular body. The sealing assembly also has one or more sleeves that removably attach between adjacent sealing elements. Adjacent sealing elements are attached to the one or more sleeves in axial alignment. A chamber is formed by the adjacent sealing elements and the corresponding sleeve. The sealing assembly further has a bearing attachment for attaching the plurality of modular sealing elements to a rotating portion of the bearing assembly such that the sealing elements extend downward in series from the bearing assembly and rotate with the rotating tubing string.

摘要： This stuffing box (46) defines a circulation passage (66) of a cable working line (28), a packer (70), and a back-pressure resistant valve (74). The passage (66) extends between an upstream end (62) of the stuffing box (46), intended to be connected to a well, and a downstream end (64). The back-pressure resistant valve (74) is arranged in the passage (66) to prevent, in case of break of the line (28), the back-pressure of a fluid from the upstream end (62) towards the downstream end (64). The or each packer (70) is situated between the upstream end (62) of the stuffing box (46) and the back-pressure resistant valve (74). No packer (70) is arranged between the back-pressure resistant valve (74) and the downstream end (64).

摘要： A connector is provided for selectively connecting or disconnecting a stripper rubber to or from drilling head equipment such as a bearing assembly. A generally cylindrical adapter (100) connected to the equipment defines a primary bore (110) to accommodate a down hole tubular. One or more cam pin bores (120), adapted to house one ore more cam pins (300), are positioned radially around the adapter (100) substantially parallel to the primary bore (110). One or more cam lock bores (130) adapted to house one or more at least partially rotatable cam locks (200), are offset from the pin cam bores (120) such that each cam pin bore partially intersects a corresponding cam lock bore (130) to form an aperture through which the cam lock (200) engages the cam pin (300). One or more cam pins (300) are connected to the stripper rubber; and one or more at least partially rotatable cam locks (200) housed in the cam lock bores (130) of the adapter (100) optionally engage or disengage the pin cams (300) to respectively connect or disconnect the stripper rubber to or from the equipment.

摘要： A wiper device is provided comprising a container (1) having a central opening (4) through which the well string may pass. A pair of opposed wiper pads (9) disposed in a horizontal attitude are mounted in spaced vertical relationship within the container (1) for longitudinal movement toward each other, to engage the vertical string. A double-acting pneumatic cylinder (25) actuates each pad. Each cylinder (25) is mounted in the plane of the pad (9), said cylinder being connected at its front end with the rear portion of the wiper pad and being pivotally connected at its rear end with a support member. The front end of the cylinder (25) is thus adapted to rotate in a horizontal plane about its pivot connection, to accommodate transverse movement of the attached wiper pad (9). The container side walls (3) are spaced from the wiper pad edges to permit such transverse movement to take place. Arrays of anti-friction rollers (8) support each of the pads. The spacing of the walls (3), pivoting capability of the cylinder (25) in a horizontal plane, and provision of the anti-friction means (8) combine to permit transverse movement of the wiper pads (9). The head ends of the cylinders (25) are interconnected by a line to enable air, displaced from one cylinder, to move to the other, to permit of longitudinal movement of the pads. The head ends of the cylinders (25) are also connected with a pulsation tank, so that if both cylinders are simultaneously contracted by passage of an enlargement through the pads (9), there is little change in wiping pressure. Thus the pads (9) can free-float with the well string, while maintaining a substantially constant wiping pressure.
