Product Description
Coiled tubing BOP
Coiled tubing BOP is a key part in well logging devices, and it is mainly used to control pressure at the wellhead during the process of well logging, well workover and production test, so as to effectively avoid blowout and to realize safe production.
A coiled tubing BOP is composed of quad ram BOP and stripper assembly.
A Quad Ram BOP can be used to perform the following operation
1. When the tubing exists in the well, with the help of packing of certain size,the BOP can close the circular space between the bore and pipe string and prevent the fluid in the well from overflowing.
2. When there is no string in the well, the BOP can completely close the well head with blind ram.
3. When in emergency, the tubing in the well goes up or down, a slip ram may be used to lock the tubing to avoid any accident.
4. When the well is closed, with the help of kill manifolds and choke manifolds connected to the spool and side outlet on the body, the BOP can realize some special operation such as throttling and relief.

Stripper assembly can be used to perform the following operation
1. When there is tubing in the well, with the help of packing of certain size, the BOP can close the annular space between the bore and tubing and prevent the liquid in the well from kicking.
2. When the tubing in the well moves up or down, turning the pressure at the stripper control oil line can protect the surface of liquid lubrication in the well and to prevent the liquid in the well from the kicking.
