    摘要: In one embodiment, a method for drilling a wellbore includes injecting drilling fluid into a top of a tubular string disposed in the wellbore at a first flow rate. The tubular string includes: a drill bit disposed on a bottom thereof, tubular joints connected together, a longitudinal bore therethrough, and a port through a wall thereof. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The cuttings and drilling fluid (returns) flow to the surface via an annulus defined between the tubular string and the wellbore. The method further includes rotating the drill bit while injecting the drilling fluid; remotely removing a plug from the port, thereby opening the port; and injecting drilling fluid into the port at a second flow rate while adding a tubular joint or stand of joints to the tubular string. The injection of drilling fluid into the tubular string is continuously maintained between drilling and adding the joint or stand to the drill string. The method further includes remotely installing a plug into the port, thereby closing the port. The first and second flow rates may be substantially equal or different.

    摘要: A system and method for setting an anchor and/or whipstock attached to a downhole motor having a cutting tool attached to a tubular member, such as coiled tubing. In one aspect, the motor allows flow therethrough sufficient to actuate an upstream MWD or other position measuring tool, and an orienter if so equipped, and retain the orientation of the motor with the attached whipstock. An increased flow rate or pressure actuates the motor once the whipstock is set and rotation of the cutting tool or other equipment can begin.

    摘要: The present invention generally provides a reduced downtime maintenance apparatus and method for replacing and/or repairing a subassembly in sealing equipment for oil field use. The invention allows the removal of rotating portions of a rotary drilling head without having to remove non-rotating portions. The reduction in weight and size allows a more efficient repair and/or replacement of a principal wear component such as a packer. Specifically, the packer in a rotary drilling head can be removed independent of bearings and other portions of the rotary drilling head. Furthermore, because of the relatively small size and light weight, the packer can be removed typically without having to use a crane to lift a rotary BOP and without disassembling portions of the drilling platform. In some embodiments, the packer can be removed with the drill pipe without additional equipment. Furthermore, the packer can be removed remotely without necessitating manual disengagement typically needed below the platform. The invention also provides a fluid actuated system to maintain a pre-load system on the bearing.

    摘要: A stripper rubber for use in a drilling head to seal against a work string deployable through the drilling head. The stripper rubber is longitudinally restrained to prevent extrusion of the stripper under pressure and to reduce the tensile and compressive stresses on the stripper rubber. One embodiment of the stripper rubber incorporates upper and lower metal rings which are maintained in spaced apart relation by vertical rods thereby allowing radial expansion as tool joints pass through the rubber but prevents inversion of the stripper rubber under pressure. Reinforcing cords added to the stripper rubber increase the longitudinal strength. A second embodiment bonds a stripper rubber into a cylinder which restrains the rubber in the vertical direction. Radial deflection is accomodated by allowing the rubber to flow vertically as a tool joint passes therethrough. Each of the stripper rubbers incorporates an integrally formed drive bushing which facilitates mounting within the drilling head.

    摘要: A rotary drilling head having an upper body incorporating a kelly bushing removably clamped onto a stationary spool. The clamp assembly is hydraulically controlled to permit remote operation and access to the drive bearings and stripper rubbers within the drilling head. Secondary manual means for unclamping the assembly are also provided. The hydraulic clamp includes an annular piston movably disposed within a cylinder and acting upon bearing members to lock and unlock the clamp assembly. Hydraulic pressure is utilized to move the piston within the cylinder. A spring biases the piston towards the locked position to prevent inadvertent unclamping.

    摘要: A geothermal wellhead repair unit including a mechanically set packer to isolate the wellhead for removal and repair thereof. The packer is run into the well string using a running tool. The packer is set by placing tension on the mandrel to set the packing elements and the slip assembly. Once the packer is set, the running tool can be disengaged without fear of collapsing the packer and the wellhead removed for repair or replacement. Upon replacement of the wellhead, the running tool is used to unset and retrieve the packer.
