摘要： Pipe-driving apparatus used to create a pipe line of small diameter uses a pressing station in an access trench to drive in pipe sections one by one. A boring head and conveyor worm operates at the front of the pipe line in a working pipe section on which a cutting shoe is swivably mounted. The worm is a spiral flight on a drive shaft which runs within an open fronted container on which a drive unit for the boring head and the worm is mounted. Hydraulic bracing units mounted to the container can be swung out and engaged with stops in the working pipe section to brace the container during the filling operation. Projections on the container engage with the shoe and the bracing units can be used to steer the shoe. When the container is filled the bracing units re stowed and the container is withdrawn back down the pipe line to the access trench for discharging the material.

摘要： A method of running a tubular string into a wellbore comprises running a bore-lining tubular string into a wellbore substantially without rotation, while rotating a cutting structure at a distal leading end of the tubular string. Other methods provide for rotation of the string and the provision of a non-rotating stabiliser towards the leading end of the string.

摘要： The disclosure of this application is directed to a downhole tool comprising a central element/member and a sleeve that is rotatably and orbitally disposed around the central element/member. The sleeve rotates and orbits around the central element/member responsive to fluid flowing through the downhole too. The disclosure is also related to a method of advancing the downhole tool in a well by flowing fluid through the tool.

摘要： In one embodiment, there is provided a system for liner drilling in a wellbore that includes a drill bit, a mud motor, a reamer, a drill pipe work string including an expandable liner hanger running tool, and a thruster coupled to an expandable liner hanger and liner. A release pin may be provided in the expandable liner hanger running tool that can be sheared to de-couple the expandable liner hanger from the expandable liner hanger running tool allowing the drill pipe work string to be removed from the borehole while the liner remains in place. A latch coupling is also provided for coupling the expandable liner hanger running tool to the expandable liner hanger when the drill pipe work string is tripped back into the borehole so the liner drilling can be performed using the thruster until the thruster is at full stroke.

摘要： A self propelling vehicle capable of propagating through a solid medium, comprising two or more rotors, arranged in tandem, and means for rotating the rotors, each rotor being formed as a hollow rotational body with an external helicoidal flighting, configured to engage surrounding solid medium, wherein the flightings of any pair of adjacent rotors follow helicoids of mutually opposite senses and the means for rotating are operative to rotate the adjacent rotors in mutually opposite senses.
