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： An expandable gripper assembly (100) may be configured for anchoring a tool in a passage. The expandable gripper assembly (100) includes first (160), second (162), and third (164) pivotally connected links that are coupled to a tool. The third link (164) is adapted to engage an inner wall in the passage. An actuation mechanism causes the third link (164) to move radially outward from the tool for engagement with the inner wall. The actuation mechanism may comprise a roller mechanism (150) that pushes on an inner surface of the first link (160) for causing the first link (160) to pivot outward away from the body (102). As the first (160) and second (162) links pivot outward, the third link (164) moves in a radial direction for engagement with an inner wall.

摘要： A long reach rotary drilling assembly comprises an elongated conduit, a drill bit (122), a 3-D steering tool (118) on the conduit, and a tractor (110) on the conduit for applying force to the drill bit. The steering tool includes a telemetry section (100), a rotary section (224), and a flex section (272) assembled as an integrated system in series along the length of the tool. The flex section (226) comprises a flexible drive shaft (244) to which a bending force is applied when making inclination angle adjustments. The rotary section (224) includes a deflection housing which rotates for making a azimuth angle adjustments. The telemetry section (100) receives inclination and azimuth angle steering commands together with actual inclination and azimuth angle feedback signals for controlling course. A propulsion assembly moves the tractor with respect to the gripper (1104) while the gripper portion is in the first position. The tractor (110) applies force to the drill bit for drilling the bore along a desired course the direction of which is controlled by the 3-D steering tool (118).
