摘要： An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured valving member with curved and flat portions that alternatively direct fluid flow through a bore or opening in the valving member via an inner channel or around the periphery of the valving member in an outer channel. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation. An optional indicator indicates to a user or operator that a ball or plug has passed a selected one of the valving members.

摘要： An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured tool body assembly having valving members (e.g., safety or kelly values) and valving members holding plugs, balls, or darts to be dropped. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation. An optional indicator indicates to a user or operator that a ball or plug has passed a selected one of the valving members. A transmitter (or transceiver) provides an ability to generate a wireless signal that is received by receivers (or transceivers) on the tool body assembly. Each receiver (or transceiver) controls an electrical actuator that engages a valving member or the indicator. Wireless signals can be used to open or close a valve or to reset a “tripped” indicator.

摘要： A wellhead assembly with a gripping device for securing multiple components of the wellhead assembly is provided. In one embodiment, a system includes a wellhead housing mounted above a hollow body, such that an axial bore extends through the wellhead housing and the hollow body, and a wellhead hanger positioned within the axial bore. The system also includes a clamp that provides a first grip that secures the wellhead housing to the hollow body and a second grip that secures the wellhead hanger within the axial bore. The second grip includes elastic deformation, via the clamp, of at least one of the wellhead housing or the hollow body into tight engagement with an exterior of the wellhead hanger to secure the wellhead hanger at the location within the axial bore. Additional systems, devices, and methods are also disclosed.

摘要： A cementing head apparatus includes a plug-launching tool and a tubular plug receiver cage disposed within a bore of the launching tool, plus one or more paddles selectively movable within a bore of the receiver cage between a hold position in which the paddles at least partially occlude the receiver cage bore to hold a plug within a retained plug interval of the receiver cage bore, and a launch position in which the paddles are substantially retracted from the receiver cage bore to allow passage of the plug through the receiver cage bore and onward into a casing string to which the launching tool is mounted. Upper and lower fluid bypass ports may be provided through the wall of the receiver cage, above and below the retained plug interval, to allow fluid flow within the receiver cage bore to bypass the retained plug interval via the receiver annulus

摘要： A method of performing an annular cementing operation after setting an integrated hanger and seal includes introducing a tubular including a flow passage having an inlet and an outlet into a wellbore, positioning and setting the integrated hanger and seal in the tubular, flowing cement between the tubular and the integrated hanger and seal into the inlet of the flow passage, passing the cement through the flow passage to the outlet, flowing the cement from the outlet, and closing the outlet.

摘要： Methods and systems for modifying a plug container to permit a fiber pass-through allowing data to be communicated from a pressurized environment into a non-pressurized environment. The systems and methods including surrounding a communication line with a protective sheath coupled with a top plug and a cap of a plug container including an elongated body having a flow path therethrough. The cap including a pass-through for receiving the communication line and obtaining data corresponding to one or more wellbore conditions including at least a temperature, a pressure, and a top plug location.

摘要： A mill for use in a wellbore includes a tubular housing having a bore therethrough and a plurality of eccentrically arranged pockets formed in a wall thereof and an arm disposed in each pocket. Each arm has a body portion and a blade portion extending from an outer surface of the body portion and is movable between an extended position and a retracted position. The mill further includes cutters disposed along each blade portion and a block disposed in each pocket and connected to the housing. Each block has a guide engaged with a mating guide of the respective body portion and an inner passage for providing fluid communication between the housing bore and the respective pocket. The mill further includes an actuator for extending the arms.

摘要： For use with a top drive power unit supported for connection with a well string in a well bore to selectively impart longitudinal and/or rotational movement to the well string, a feeder for supplying a pumpable substance such as cement and the like from an external supply source to the interior of the well string in the well bore without first discharging it through the top drive power unit including a mandrel extending through a sleeve which is sealably and rotatably supported thereon for relative rotation between the sleeve and mandrel. The mandrel and sleeve have flow passages for communicating the pumpable substance from an external source to discharge through the sleeve and mandrel and into the interior of the well string below the top drive power unit. The unit can include a packing injection system and novel seal configuration.
