    摘要： A drilling apparatus connectable with a drill pipe and connectable with a drilling assembly comprising a drilling assembly housing, for use in drilling a borehole, including a rotation restraining device actuatable between a retracted position and an extended position, a rotation restraining device actuator for actuating the rotation restraining device between the retracted position and the extended position, a swivel actuatable between a locked position and an unlocked position, and a swivel actuator for actuating the swivel between the locked position and the unlocked position. A method for drilling a borehole, including connecting a drilling assembly with a drill pipe, wherein the drilling assembly comprises a drilling assembly housing, drilling while rotating the drill pipe and thereby rotating the drilling assembly housing, and drilling while rotating the drill pipe relative to the drilling assembly housing.

    摘要： Systems and methods presented herein include a downhole well tool having an electromechanical joint configured to connect to a downhole well tool component within a wellbore of an oil and gas well system. The electromechanical joint is configured to rotate to facilitate connection of the electromechanical joint to the downhole well tool component. For example, the electromechanical joint includes a main body portion, a rotating ring configured to rotate relative to the main body portion to facilitate connection of the electromechanical joint to the downhole well tool component, and a sealed electrical connection configured to couple with a mating electrical connection of the downhole well tool component.

    摘要： An oil well rotating cement head includes a swivel assembly and a plug launcher assembly. The swivel assembly includes a swivel shaft and a collar-shaped, outer swivel subassembly. The swivel shaft has an internal through bore and windows extending through the swivel shaft, and extends through the outer swivel subassembly. The swivel shaft and outer swivel subassembly enclose an inner annular gap in fluid communication with the windows of the swivel shaft. A material inlet formed in the outer swivel subassembly is in fluid communication with the inner annular gap. The plug launcher assembly is affixed to the swivel shaft and releasably holds one or more oil well cementing plugs. The plug launcher assembly provides fluid communication from the internal through bore of the swivel shaft to a bottom end of the plug launcher assembly.
