摘要： A multi-functional apparatus and method for drilling fluid and cementing operations to set casing in a wellbore for use on either top drive or rotary type rigs. The apparatus and method includes a fill-up and circulating tool, a cementing head assembly, and a wiper plug assembly. The fill-up and circulating tool comprises a mandrel with a packer cup fixedly attached to a sliding sleeve disposed about the outside diameter of the mandrel. The cementing head and wiper plug assemblies are useable on any fill-up and circulating tool capable of being inserted into a casing. To fill the casing, the assembly is lowered from the rig such that a portion of the fill-up tool is inserted into the casing, the pumps are then actuated to flow fluid into the casing. To circulate fluid, the tool is lower further such that the packer cup sealingly engages the inside diameter of the casing to allow fluid to flow through the casing, into the wellbore, and back to the fluid pumps. To cement the casing, the cement pump and hose assembly is connected to the cementing head to allow cement to be pumped through the fill-up and circulating tool and into the casing string. A cement plug assembly comprising a plurality of wiper plugs is connected to the outlet of the fill-up and circulating tool. The wiper plugs are then released at a predetermined time during the cementing process to provide a positive seal at the bottom of the casing string.

摘要： An example of a method for cementing a casing within an earthen formation includes the steps of providing a gripping mechanism connected to a cementing assembly and a top drive; gripping the casing with the gripping mechanism; sealingly engaging the casing with a seal member; moving the casing to a position within the formation; and cementing the casing within the formation while maintaining a gripping and sealing engagement of the casing. The step of cementing may also include the step of remotely releasing a plug into the casing from the cementing assembly.

摘要： A downhole apparatus is described as having an upper mandrel shearably connected to a lower mandrel by a first set of shear pins. Each of the mandrels has an elastomeric cement plug formed around the mandrels. A sleeve is shearably connected within the lower mandrel. The operation of the apparatus, which includes a method for controlling the flow of fluid out of the end of a tubular string, involves dropping a first small diameter ball from the earth3 s surface. The ball is sized such that it travels through the upper mandrel and settles into the sleeve which is connected within the lower mandrel. By increasing pump pressure at the earth's surface, the lower mandrel is separated from the upper mandrel by shearing the first set of shear pins. After the separation of the lower mandrel from the upper mandrel, by further increasing the pump pressure at the earth's surface, a second set of shear pins are sheared and the lower mandrel can be pumped down to the bottom of the tubular string against a float collar or other plug landing surface. This enables the fluid within the tubular string to be pumped out of the lower mandrel into the earth borehole. When it is desired to separate the upper mandrel from the tubular string, the second, larger ball is dropped from the earth's surface and is seated within the upper mandrel. By further increasing the pump pressure, the upper mandrel is separated from the tubular string and can be pumped down against the lower mandrel.

摘要： A housing is attached to a tubular sub located within a tubing string suspended in an earth borehole, the connection being an angled ball channel connected between the housing and the tubular sub. A ball carrier is provided within the interior of the housing which can be moved in two opposite directions either using pneumatic or hydraulic pressure against one or two pistons. The ball carrier can have either two balls or three balls. The movement of the ball carrier by the applied pressure causes one of the pockets holding the balls to be aligned with the ball channel which allows the balls to be successively dropped into the ball channel and thus into the interior of the tubing string. The ball carrier includes a sequencing apparatus for providing and ensuring that the balls are dropped in the proper sequence.

摘要： A cylindrical ring sized to slide over the box end of an oilfield tubular having a given diameter, has a shoulder at one its ends and a sidewall along its length. The sidewall has a circumferential groove about its interior surface housing a band which can be made tight against the exterior surface of the oilfield tubular by a latch accessible through a slot in the sidewall, and which becomes even tighter if the tubular attempts to escape from the band. In a first orientation, the cylindrical ring is used as a load ring. By turning the cylindrical rings upside down, the cylindrical ring is used as a thread protector for the pin end of the tubular.

摘要： The apparatus of the present invention provides a top drive supported tool for making up and running casing strings into a borehole. The tool comprises a fill-up and circulation assembly and a launcher assembly that is adapted to cooperate with a connectable cement wiper plug assembly for launching wiper plugs that control cement placement in the annulus between a casing string and a borehole containing the casing string. The tool of the present invention shortens or eliminates delays in well operations, thereby improving integrity of cement liners formed by placing cement slurry in a targeted interval.
