Steam injection and oil recovery dual tubing wellhead
Sanjack has more than 40 years of experience in oil and gas wellhead & x-mas tree and API 6A valve production, with advanced manufacturing and testing equipment, can produce a variety of pressure levels, material levels, specification levels of well control equipment. After more than 20 years of development, Various types of thermal recovery wellhead & x-mas tree equipment have been formed, used in many oilfields in the world. Sanjack’s thermal recovery wellhead & x-mas tree are mainly of the following types:
- Conventional Steam injection and oil recovery wellhead & x-mas tree
- Onshore thermal recovery oil and gas wellhead & x-mas tree
- Single column dual-well thermal recovery wellhead & x-mas tree
- Steam injection and oil recovery dual tubing wellhead & x-mas tree
- Blowout preventer Steam Injection and Oil Recovery Integration wellhead & x-mas tree
- Geothermal wellhead & x-mas tree
Steam injection and oil recovery dual tubing wellhead & x-mas tree is applicable for continuous and intermittent thermal recovery of heavy oil well.
The main feature of the oil and gas wellhead & x-mas tree is that, under the condition of high temperature and pressure, the steam injection channel, oil production channel, casing annulus, and the outside air are sealed to each other and not connected, so that the steam injection and oil recovery can be carried out at the same time.
This structure oil and gas wellhead & x-mas tree improves steam injection efficiency and oil recovery efficiency.
The steam injection and oil recovery dual tubing wellhead & x-mas tree are provided with a pressure release pipe, which can lead the excessive pressure inside the tubing into the casing, and play the role of pressure releasing inside the tubing and pressure boosting inside the casing.
The wellhead & x-mas tree can avoid pressure leakage and reduce the occurrence of accidents.
