摘要： An apparatus including a rotating segment having a first radial surface, a non-rotating segment having a second radial surface, a housing disposed around the first and second radial surfaces, and one or more rolling elements disposed between and in contact with the first and second radial surfaces for transferring the non-rotating segment in an axial direction upon rotation of the rotating segment. The non-rotating element may be a second rotating element that rotates at a different rotational rate than the rotating element. Each rolling element moves 360 degrees along a circular path relative to the first radial surface and the second radial surface. The first or second radial surface has a tapered section. A downhole apparatus includes a power mandrel having a first end connected to a power section member and a second end having a rotating cam surface; a rotating element engaging the rotating cam surface; an anvil sub attached to a workstring, with the anvil sub having a stationary cam surface configured to engage with the rotating cam surface. Rotation of the rotating cam surface moves the anvil sub and the workstring axially within the wellbore.

摘要： An exemplary embodiment of the downhole oscillator includes an outer housing at least partially surrounding a motor and a removably coupled eccentric member. The motor at least partially drives the rotation of the eccentric member thereby producing oscillations or vibrations along the outer diameter of at least a portion of the downhole assembly. The motor's action is at least partly facilitated by expulsion of fluid from the drill string through the motor and onto the outer housing interior such that the force of the fluid produces rotation in the motor. Rotation may be enhanced through similar expulsion of fluid from the eccentric member. Alternatively, the fluid may be expelled from the motor and/or eccentric member against the wellbore thereby providing the desired rotation. A method of use may include providing an outer housing, motor capable of producing rotational movement, and eccentric member and coupling same.

摘要： A driving device for installing a pipe or casing, without the use of hydraulic or pneumatic means, by capturing the rotational motion of the drill string. The driving device is placed at the top end of the pipe being (42) installed and the drill string (2) passes through the center of the device. The drill string freely rotates, advances or retracts within the driving device, until the driving device is attached (4) to the drill string when required. When the driving device is attached to the drill string, the rotational force of the drill string and any downward force applied to the drill string are captured, and used to install the pipe. The driving device uses the rotation of the drill string to impact a blow to the pipe, driving the pipe downward. The driving device uses any downward force applied to the drill string to maintain downward pressure on the pipe.
