摘要： A pulling tool for use in a pipe or wellbore has a motor (3) connected to several hydraulically activated levers (5) for forcing drive wheels (4) against an inner surface of the wellbore. A coupling device (2), disposed between the motor (3) and levers (5), has an incoming shaft (12) with sloping surfaces (25) at the end. An outgoing shaft (15) has rollers (24) distributed on an adapter (17) at its end, such that the rollers (24) engage the sloping surfaces (25) on the incoming shaft (12). When a torque is applied to the incoming shaft, a relative rotation between the incoming shaft (12) and outgoing shaft (15) causes an axial displacement of the adapter (17). This axial displacement controls, pistons providing a hydraulic pressure. forcing the levers (5) outwards, thus forcing the wheels (4) against the inner surface of the pipe or wellbore.

摘要： An electrically powered and controlled tractor system includes one or more electric gripper assemblies (20) and one or more electric power train assemblies (30). Power and control signals for the gripper assemblies (20) and power train assemblies (30) can be delivered from a ground surface via a wireline (40). The gripper assembly (20) employs a motor-activated lead screw (216) and nut (214) combination to expand passage-gripping elements (206), preferably by pushing the gripping elements (206) radially outward from locations between opposing ends (207) of the gripping elements (206). A failsafe mechanism can retract the gripping elements (206) during a power interruption. The power train assembly (30) employs a motor-activated lead screw (312) and nut (314) combination to expand and contract two ore more telescoping members (302, 304, 306). The tractor system can include multiple tractor units (10) that each includes one gripper assembly (20) and one power train assembly (30). A tractor (700) can include one power train assembly (720) and two gripper assemblies (730).

摘要： A fluid conduit sheath (18) for a wellbore tractor (10) can provide transportation of a working fluid external to a wellbore tractor in a downhole environment. The fluid conduit sheath can further provide cooling to electrical devices in the wellbore tractor. The fluid conduit sheath can be configured to be disposed around the body (12) of the wellbore tractor, defining a fluid conduit (22) between the sheath and the wellbore tractor. Spacers (36) can be used to maintain the position of the sheath relative to the tractor and also to couple the tractor to the sheath. The fluid conduit sheath can be advantageous in tractors whose internal components substantially preclude the use of an internal fluid conduit, such as tractors with electrically-actuated grippers.

摘要： A hydraulically powered tractor 100 adapted for advancement through a borehole including an elongate body, aft and forward gripper assemblies 104, 106, and a valve control assembly 102 housed within the elongate body. The aft and forward gripper assemblies 104, 106 are adapted for selective engagement with the inner surface of the borehole. The valve control assembly 102 includes a gripper control valve 312 for directing pressurized fluid to the aft and forward gripper assemblies 104, 106. The valve control assembly 102 also includes a propulsion control valve 310 for directing fluid to an aft or forward power chamber for advancing the body relative to the actuated gripper assembly. Aft and forward mechanically actuated valves 322, 324 may be provided for controlling the position of the gripper control valve 312 by detecting and signaling when the body has completed an advancement stroke relative to an actuated gripper assembly. Aft and forward sequence valves 314, 316 may be provided for controlling the propulsion control valve 310 by detecting when the gripper assemblies become fully actuated. Furthermore, a pressure relief valve 306 is preferably provided along an input supply line 302, 352 for limiting the pressure of the fluid entering the valve control assembly 102.

摘要： A flowline is described for producing hydrocarbons from a subsea well that is comprised of a substantially neutrally buoyant tubular composite umbilical. The flowline may possess electrical heating apparatus within the tubular walls of the tubular composite umbilical to prevent waxes and hydrates from forming within the flowline and blocking the flowline. The electrical heating apparatus is comprised of at least one electrical conductor disposed within the tubular walls of the composite umbilical that conducts electrical current that is used to heat the tubular composite umbilical. The tubular composite umbilical that contains any produced hydrocarbons is substantially neutrally buoyant in the sea water adjacent to the subsea well. Positively neutrally buoyant tubular composite umbilical flowlines are also described.

摘要： A retrievable pig apparatus (10) having a substantially cylindrical body portion (32), the body portion (32) having a central flow bore (34) therethrough, and secured to coiled tubing (22), including a central fluid flow bore (34) in fluid communication with the interior bore of the coiled tubing (35); a plurality of flow bores (40) spaced equally apart within the body, with the flow bores (40) allowing fluid flow to be injected at a certain predetermined pressure through the flow bores (40), so as to be emitted on the front end of the pig for defining a high pressure spray of fluid or the like material to break up blockages of debris (70) in the pipeline, such as paraffin or the like; the debris (70) retrieved through the central bore (34) back into the coiled tubing (35) to be stored in a tank (157) or the like on the surface. There is further included a plurality of flexible cups (24), spaced apart along the outer wall of the pig body (25), each cup (24) secured to an interior metallic ring (26) around the body (25) of the pig, with the flexible cups (24) making contact with the wall (13) of the pipeline so as to provide a continuous fluid seal between the wall (13) of the pipeline and the ends of the plurality of flexible cups (24). Intermediate each cup (24) there is provided a compressible safety ring (28), which will compress under excess pipeline pressure, thus allowing the fluid to flow past the plurality of flexible cups (24), reducing the pressure in the pipeline. Further there is provided within the plurality of six flow bores (40) around the interior flow bore (34), for adjusting the force that is allowed to flow through the plurality of bores (40) in either direction by providing a first and second thruster springs (42, 44) of a pre-determined compressible force for allowing the springs (42,44) to be compressed and effecting fluid flow therethrough in the direction in which the flow is to travel in the bores (40).
