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： An attachment and fastener system rigidly secures a rotatable drill pipe protector (RDPP) to a drill pipe. The RDPP comprises a sleeve which is split axially along at least one side. Parallel hinge bars are contained in first (22) and second (26) hinge sections which wrap around the hinge bars along opposite sides of the opening in the RDPP. One hinge bar (38) is rotatable in the first hinge section. A series of axially spaced apart bolts (32) are held in corresponding threaded openings in the rotatable hinge bar which rotates about its axis to swing the bolts in unison between open and closed positions. The other hinge bar (40) has a series of threaded receptor openings facing outwardly from slotted openings in the second hinge section and aligned with the bolts on the other hinge bar. The rotating hinge bar swings the bolts into alignment with the slotted openings in the other hinge, after which the bolts are tightened in the threaded receptor openings for applying a holding force around the drill pipe.

摘要： An anti-stall tool in an oil well drilling assembly that controls reciprocation of the drill bit by a controller that alters weight-on-bit (WOB) depending upon measured downhole pressure or torque at the downhole motor. The controller receives preset high and low working pressure limits for the downhole motor and keeps the drill bit rotating by maintaining WOB during normal drilling operations, increasing WOB if sensed working pressure indicates that drill bit loading or torque is undesirably low, and reversing WOB by retracting the drill bit if excessive working pressure or torque is sensed.

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 drill pipe/casing protector assembly (18) for an underground drilling system comprises a well bore in an underground formation, a fixed tubular casing (16) installed in the well bore (14), a rotary drill pipe (12) extending through the casing (16) and having an O.D. spaced from an I.D. of casing (or well bore) during normal drilling operation, and a protective sleeve (18) mounted around the drill pipe and spaced from the I.D. of the casing, and upper and lower thrust bearings (22, 24) affixed to the drill pipe above, and below the sleeve to retain the sleeve in a fixed axial position on the drill pipe. The sleeve (18) contacts the I.D. of the casing when the drill pipe (12) deflects off-center to protect the casing from contact with the drill pipe or its tool joints during rotation of the drill pipe. Axial grooves (26) in an I.D. wall of the sleeve allow fluid under pressure to circulate through a space formed between the I.D. of the sleeve (18) and the O.D. of the drill pipe. Generally flat bearing surface regions (32) on the I.D. wall of the sleeve between adjacent grooves (26) are arranged in a polygon configuration for tangentially contacting the O.D. of the drill pipe around the sleeve I.D. The sleeve (18) separates from the O.D. of the drill pipe upon circulation of a fluid film under pressure between the sleeve (18) and the drill pipe (12) to produce a fluid bearing effect with reduced frictional drag. End slots at the top and the bottom annular end walls of the sleeve provide enhanced fluid bearing effects in the clearance regions between the sleeve and the adjacent thrust bearings (22, 24).

摘要： A tubing friction reducer (32) is mounted on a length of tubing within a bore hole. The friction reducer (32) comprises a cylindrical body (34) having a first section and a second section hingedly secured (40) around an exterior surface of the coiled tubing (18), the cylindrical body (34) having an outside diameter of an adjacent bore surface. A plurality of ball bearings (88) are positioned on and extending outwardly from the cylindrical body (34) extending in a generally axial direction along the cylindrical body (34) for the purpose of reducing friction between the coiled tubing (18) and the bore surface generated upon contact between the coiled tubing (18) and the bore surface. Retaining mechanisms such as collapse springs (92) are included for securing the ball bearings (88) to the cylindrical body (34). The tubing friction reducers (32) are placed along the tubing (18) at intervals to either minimize injector force or prevent buckling and tubing failure due to wear.
