摘要： A sealing apparatus includes a moveable seal holder with a cavity and includes a seal assembly disposed at least partially in the cavity. The seal assembly includes a resilient seal member including a fluid-facing end with a fluid-facing end surface, and the seal assembly includes an actuator plate configured to reciprocate between a first and a second position relative to the protective plate. The first actuator plate includes a fluid-facing end surface and a first camming surface. The seal assembly further includes a first protective plate disposed between the seal member and the first actuator plate. The actuator plate is configured to compress the seal member and to move the fluid-facing end surface of the seal member outward from a resting position when the actuator plate is in the second position.

摘要： An overpressure control apparatus is used to control jets of high-pressure fracking fluid or other stimulation fluid released from a treatment flowline in cases of overpressure. The apparatus includes a collection tank and one or more valves, which can all be mounted on or integrated to a skid. The sizes and weights of the collection tank and the skid may help to keep the apparatus on the ground during an overpressure event. The apparatus can be provided with an offline testing system that allows an operator to close off the communication between the apparatus and the treatment flowline, and instead, pump a clean fluid such as water at high-pressure to test the proper functioning of the valve.

摘要： A power swivel is disclosed that is configured to rotate tubular string and drill bit to form or extend a subterranean borehole. In an embodiment, the power swivel includes a motor, a gear box coupled to the motor, and a lubrication system coupled to the gear box. The lubrication system includes a pump disposed within the gear box, the pump including an outlet. In addition, the lubrication system includes a recirculation line fluidly coupled to the outlet of the pump. Further, the lubrication system includes a first injector fluidly coupled to the recirculation line. The injector is configured to deliver lubricant to one of a bearing and a gear disposed within the gear box.

摘要： Reaming tools for reaming a borehole and related systems and methods are described herein. In an embodiment, the tool includes a body having a central axis, and a plurality of blades. Each of the plurality of blades includes an uphole section that extends in a first helical direction, a downhole section that extends in a second helical direction that is opposite the first helical direction, and an arcuate central section that continuously extends from the uphole section to the downhole section. The plurality of blades are eccentric about the central axis such that the reaming tool is configured to pass axially through a first diameter and is configured to ream a borehole to a second diameter that is greater than the first diameter when the tool is rotated about the central axis in a cutting direction.

摘要： A system for manufacturing a tubular member includes a mandrel configured to be inserted within a throughbore of the tubular member to engage with an inner diameter of the throughbore. In addition, the system includes a die assembly comprising a cavity. The die assembly is configured to be disposed about an outer surface of the tubular member such that a central portion of the tubular member is aligned with the cavity. Further, the system includes a ram configured to apply a load to the tubular member along a central axis of the tubular member to expand the central portion of the outer surface of the tubular member into the cavity to form an upset region along the tubular member.

摘要： A pipe handling system for handling drill pipe on a drill rig may include a lifting system configured for handling a load of a pipe stand and a first pipe handling robot arranged at or near a drill floor of the drill rig and configured for manipulating a bottom end of the pipe stand between a setback area on the drill floor and well center. The system may also include a second pipe handling robot arranged at or near a racking board of the drill rig and configured for manipulating a top end of the pipe stand between the racking board and well center. The first pipe handling robot may have a base that is supported from a location outside a plan view envelope of the setback area of the drill floor.
