Casing running rigging unit

The TXGN‑type casing‑running unit is a mechanically integrated tool designed for casing‑running operations. It is mounted on the top drive via an adapter. The unit can perform casing suspension, make-up, cementing, circulation, and casing rotation, thereby addressing the challenges of casing running in complex well conditions. Additionally, it can be equipped with a wireless torque‑measurement system to monitor make‑up torque and other parameters.

Product Details

  The TXGN-type casing‑running unit is a mechanically integrated tool for running casing, mounted on the top drive via an adapter.

  The device can perform casing suspension, make-up, cementing, circulation, and casing rotation, thereby addressing the challenges of running casings in complex well conditions. It can also be equipped with a wireless torque‑measurement system for monitoring make‑up torque and other parameters.

  Integrated functionality and reduced staffing have enhanced operational efficiency. Remote operator control has improved job safety. When combined appropriately with other tools, this approach has ushered in a significant new breakthrough in casing‑running operations.

  This device has been granted a national invention patent (Patent No.: ZL 202211238609.3).

  The TXGN Casing Running Tool is a mechanically integrated casing‑running device. It is mounted on the top drive’s drill pipe joint, with both gripping and rotational operations controlled by the driller, who also manages its mechanical activation and release. Installation and removal are quick and straightforward, requiring no external pipelines or power sources.

  The device can perform casing suspension, make-up, cementing, circulation, and casing rotation, thereby addressing the challenges of casing running in complex well conditions.

  By replacing the chuck and sealing units according to actual requirements, it can accommodate casings of various sizes and pressure ratings, enabling multi‑purpose operation with a single unit.

  Integrated functionality and reduced staffing have enhanced operational efficiency. Remote operator control has improved job safety. When combined appropriately with other tools, this approach has ushered in a significant new breakthrough in casing‑running operations.
