Offshore wellhead X-mas tree
Fracture wellhead and X-mas tree is used for coiled tubing fracturing and unconventional oil and gas recovery fracture, make a large number of fracture liquid injecting into formation and control the wellhead pressure.
Offshore wellhead and X-mas tree is designed to solve the problem of space limitation faced in offshore platform oil and gas wells, and adopts a complex integral design. This offshore wellhead and X-mas tree is usually machined from one steel bar, thus decreasing the overall height of wellhead and X-mas tree equipment. To increase its safety, this equipment is fitted with a hydraulic safety valve.
Offshore wellhead and X-mas tree equipment has an integral BIW cable type and three single cable types to suit different requirements.
- Combined master valve and swab valve to decrease the offshore wellhead & X-mas tree height
- Hydraulic safety valve in main drift diameter to achieve remote shutdown of wellhead in an emergency
- Segregated tubing head spool. Top and bottom parts are connected by insert type locking piece. This structure means the X-mas tree could be adjusted in any direction during installation.
- Equipped with BIW cable penetration and fitted adapter flange and hanger.
