摘要： A drilling rig includes a rig floor, first and second support structures, a mast, a lower drilling machine, a continuous drilling unit, an upper drilling machine, and an upper mast assembly. The rig floor includes a V-door defining a V-door axis extending perpendicularly from the side of the rig floor that includes the V-door. The first and second support structures define a traverse corridor having a traverse corridor axis, wherein the traverse corridor axis is perpendicular to the V-door axis. The drilling rig may be used for continuous drilling of a wellbore.

摘要： An adapter for coupling wellhead pressure control equipment to wellhead mounted equipment, includes a breech pin and a breech lock base assembly. The breech pin includes a tubular breech pin body and a rotating breech ring. The rotating breech ring is coupled to and rotatable relative to the breech pin body. The rotating breech ring includes a breech ring body and one or more breech pin teeth extending radially outward from the breech ring body. The breech lock base assembly includes a tubular base assembly body. An upper end of the bore of the base assembly body defines an upper receiver. The breech lock base assembly includes a fixed retaining ring including one or more fixed breech teeth. The fixed breech teeth extend radially inward into the upper receiver. The fixed breech teeth are positioned to correspond with the spaces between the breech pin teeth.

摘要： An outlet and nightlight device with a solid base. The base has a front, back, top and two outlets on the front the base. There are two plugs on the back of the base, a light sensor, and a light emitter. The front of the base is attached to a raised section which is attached and in moveable communication with a face plate. In some embodiments the face plate slides across the raised section and in others it can rotate away from the raised section via a hinge on the base plate. The light sensor can trigger to the light emitter to emit light in low light conditions and in some embodiments there is a manual trigger for the light emission. In some embodiments the base has USB port for utilization. In some embodiments the face plate can lock to the base plate. In some embodiments the present invention has ancillary light emitters on the raised plate. In some embodiments of the invention there is a battery back up to supply energy to the light emitter in case of power failure.

摘要： Embodiments presented provide for an apparatus that provides a dislodgable plug seat that is used to capture a cement wiper plug for wellbore cementing operations. The apparatus further includes a collar having a ball seat and a closing sleeve configured to be shifted from an open position to a closed position. In the open position, a fluid pathway between an interior volume and a wellbore annulus is unblocked, and in the closed position the fluid pathway is blocked. A split ring is shiftable with the closing sleeve between a retained configuration when the closing sleeve is in the open position and an expanded configuration when the closing sleeve is in the closed position. The split ring holds the dislodgable plug seat in place within the body in the retained configuration and releases the dislodgable plug seat in the expanded configuration.

摘要： A rotary pump housing having a cylindrical bore, a pumping chamber and a motor stator including an electrically conductive coil located within the housing and surrounding a portion of the cylindrical bore. A rotor has a cylindrical shaft with an impeller and one or of magnets located within the shaft that are responsive to the motor stator to drive actuation of the rotor. The housing bore is closely fitted to the outer surface of the shaft forming a hydrodynamic journal bearing with an annular clearance defining a leakage flow path. One or more of radial or axial thrust bearings may be provided to provide rotation stability to the rotor and flow within the leakage flow path. The relative orientation of positions of the inflow, outflow, and leakage flow paths may be varied within the pump, such as to accommodate different intended methods for implantation and/or use.

摘要： A modular tool anchor includes an anchor body positionable about a tubular. The anchor includes an anchor wedge for gripping against the tubular. A wedge drive screw engages a piston that biases the wedge into contact with the tubular as the wedge drive screw is tightened. The anchor also includes a compression seal positioned within the anchor body. A sealing flange abuts the compression seal. As seal compression screws are tightened, the sealing flange engages the compression seal and forces it against the tubular.

摘要： A drilling rig may include a mast and a top drive system. The mast is aligned with a wellbore, the wellbore defining a wellbore centerline. The top drive system may include a top drive. The top drive is movable vertically relative to the mast. The top drive is movable horizontally between a position aligned with the wellbore centerline and a position out of alignment with the wellbore centerline.
