摘要： A snubbing unit drilling system (1) that includes a power tong (2) and a hydraulically activated back-up tong (3). A mounting structure (20) having a rotating slip assembly (5) positioned on the mounting structure (20) such that the rotating slip assembly (5) rotates relative to said mounting structure (20). A plurality of support legs (16) are attached between the power tong (2), the back-up tong (3), and the mounting structure (20) such that the support legs (16) prevent relative rotation between the power tong (2) and the mounting structure (20).

摘要： Closed head power tongs (200) used to make up and break threaded pipe joints are disclosed herein. The closed head power tongs (200) have removable mating inserts (301, 302) that allow the gripping aperture (205) of the power tongs (200) to be increased so that objects larger than the gripping diameter of the tongs (200) can be raised or lowered through the center aperture (801) of the power tong (200) without removing the tongs from alignment with the drill string (120).

摘要： A power tong set (9), with lead and back-up tongs (9a, b), is mounted on the slip bowl (7) of the traveling jack head (6) of a snubbing unit (2) and rotates with the slip bowl (7). Service lines (or umbelicals) for the tong set are not connected during string (ps) rotation. In an alternate version of the apparatus, a fluid feed through swivel (11) is mounted on the tong set (9), secured to the necessary tong operating and control service fluid line, or lines, such that the tong set (9) can rotate with tong service lines between the tong set (9) and the snubbing unit (2) during rotation. In an alternate form, the tong set (9) is mounted on the jack head (6), independently of the rotary table, and the tong set (9) does not rotate when the rotary table rotates.

摘要： Apparatus for positioning a power tong at a desired location with respect to the distance above the rig floor, and with respect to the center of the rig floor. A pedestal is secured to the structure of the rig. An upright member is mounted on the upper end of the pedestal, with a bearing disposed between the upright member and the pedestal, the bearing permitting the upright member to rotate around a vertical axis when moved by a powered ring gear assembly. A telescoping boom is rotatably mounted on the upright member, and one end thereof extends over the central part of the rig floor. Power tongs attached to the boom may thereby be positioned at desired positions with respect to the rig floor. Controls mounted on the power tongs and/or on the upright member permit control of the rotation of the boom, the upright member, ang the power tong.
摘要翻译：用于将动力钳定位在相对于钻台底部上方的距离以及相对于钻台底部中心的期望位置的装置。底座固定在钻机的结构上。直立构件安装在基座的上端，轴承设置在直立构件和基座之间，该轴承允许直立构件在由动力齿圈组件移动时围绕竖直轴线旋转。伸缩式吊杆可旋转地安装在直立构件上，并且其一端在钻台底部的中心部分上延伸。附接到吊杆的动力钳可因此定位在相对于钻台的期望位置处。安装在动力钳和/或直立构件上的控制装置允许控制悬臂，直立构件和动力钳的旋转。
