Development and application of wheel slip continuous loading snubbing device

For a common snubbing device, to carry out manager of moving pipe by fixed clamping and the sliding clamping device’s alternating clamp operations leads to many slow operating produces.Wheel slip continuous loading snubbing device was developed, it was designed a loading control system and a wellhead sealing blowout prevention system, can load control through hydraulic motor driven head rolling, and seal blowout prevention technology consistsing of built-in self sealed ball wellhead sealing and semi closed, realize the pipe column clamp quickly, and pipe column sealing blowout preventer. The advantages of device is high loading efficiency, fast speed, safety and reliability. The field application results show that the design of device meeting the needs of low snubbing operation.
