The drilling rig of a preferred embodiment of the present invention utilizes specialized positioning pads integral to the side boxes of the drilling rig to facilitate the connection of the center drill floor of the drilling rig to the side boxes of the rig. A preferred embodiment of the present invention may also utilize a specialized positioning dolly and an adjustable fifth-wheel truck connection for transporting the mast to the drill site, assembling the mast sections together, and positioning the mast for connection to the drill floor of the rig. The result is a unique drilling rig design and sequence for assembly that significantly reduces the time required to transport the rig from location to location and to assemble the rig at the drill site.

The invention relates to an improved drill pipe spinner. The improved spinner may be used as a stand-alone piece of pipe handling equipment or may be used in an Iron Roughneck. The spinner comprises a pair of clamping arms that are movable between an open position and a closed position, wherein in the closed position, the arms will clamp about a pipe to be made up or broken out and in the open position, the spinner may be moved away from or towards the pipe. The arms are preferably moved between the open and closed positions by a hydraulically actuated clamping cylinder. Attached to the distal ends of each arm is a roller bracket. The roller brackets are preferably attached to the clamping arms by a roller bracket pin. Each roller bracket includes a pair of drive roller assemblies, which together form the spinning unit. Each drive roller assembly preferably comprises a pair of drive rollers, with each roller rotated by a pair of hydraulic motors. If the rollers of the spinner have to be repaired, serviced or replaced, the arm brackets are easily removed by simply pulling the roller bracket pin and removing the roller bracket. A new roller bracket may then be picked up, aligned with and pinned to the arm by reinserting the roller bracket pin. The spinning unit can easily be removed and replaced on the rig floor by changing out the roller bracket.

A method and apparatus for moving pipe on a rig floor between a number of different stations including an off-floor rack, a preparation opening, a borehole, and a storage area, such that tubulars can be loaded onto the drill floor, prepared at the preparation opening, loaded onto or off of the storage rack, and connected to a drill string while drilling is simultaneously conducted at the borehole, comprising at least two pipehandling devices, at least one of the pipehandling devices having multiple independent gripping arms, the pipehandling devices being arranged for communicating pipe between a storage area off the drill floor, a storage area on the drill floor, at least one preparation opening, and a drill opening are provided.

A transportable drilling rig having a self-elevating drill floor includes a base structure comprising multiple base towers that can be transported to a wellsite and positioned around an intended wellbore location. A horizontal base frame is installed between lower regions of the towers to form a stable rig base structure, and a drill floor can then be constructed over the base frame and between the base towers. A suitable rig mast can then be erected on the drill floor. Floor-lifting cables are anchored to upper regions of the base towers and disposable around corresponding sheave assemblies associated with the drill floor. The free ends of the floor-lifting cables can be engaged by the traveling block in the rig mast, whereupon the rig's drawworks can be actuated to elevate the drill floor and mast as required and then locked to the base towers.

A gas and oil recovery system including a vessel, platform or rig, with a rig floor, a riser including a pipe that extends from the vessel, platform or rig to a x-mas tree on top of a well head and via which a wire or coiled tubing is fed down into a well. The riser is movable through an opening in the rig floor, and a surface flow head connected to the riser and to a wire line or coiled tubing equipment. The surface flow head is arranged to be run through the opening in the rig floor.

A tubular tool body carried at the end of a drilling rig top drive is received within a drill string being used as a landing string to position casing in a wellbore. External threads on the tool body can be mated with the box threads of the drill string to secure the top drive and drill string together for simultaneous drill string movement and fluid circulation. An annular seal carried about the tool body engages and seals with the internal wall of the drill pipe to prevent drilling fluid leakage when the tool body is received within the drill pipe without thread engagement. The tool has an internal check valve that opens to allow back flow of drilling fluid that may be displaced from the drill pipe as the pipe is lowered into the well. The check valve prevents standing fluid in the top drive from spilling onto the rig floor when the tool is withdrawn from the drill string. Pump pressure applied through the top drive axially moves the check valve against a biasing spring to open a bypass through the wall of the tool to permit forward circulation through the drill string and casing. The spring bias force is sufficient to withstand the hydrostatic force exerted by the standing column of fluid in the top drive and associated piping.

A method for casing job by using a top drive drilling unit is applied to the petrol cementing technique field, and is characterized in that a casing elevator is used for lifting a single casing which is buckled with a casing string oppositely; a top-driven casing device is driven to tightly clamp the single casing; the top drive drilling unit is driven to revolve, which allows the single casing to be connected with the casing string; an air slips of a drill stand is loosed, which allows a top-driven flying ring and the casing elevator to support the single casing and the casing string; the single casing and the casing string are lowered; the air slips of the drill stand is used for fixing the single casing; slurry is poured to the interior cavities of the single casing and the casing string through a chief axis hydrophthalmia of the top drive drilling unit and a central spindle hydrophthalmia of the top-driven casing device; and finally, all the casing strings are lowered to the well bottom. The method has the advantages of reducing working equipments, simplifying working process, being capable of revolving casing string and cycling slurry timely according to the actual needs, increasing the automatic degree of the casing job, and improving the production efficiency and safety.
