Steam injection and oil recovery dual tubing wellhead
Sanjack’s thermal recovery wellheads are mainly of the following types:
- Conventional Steam injection and oil recovery wellhead
- Onshore thermal recovery oil wellhead
- Single column dual-well thermal recovery wellhead
- Steam injection and oil recovery dual tubing wellhead
- BOP Steam Injection and Oil Recovery Integration Wellhead
- Geothermal wellhead
Sanjack has more than 40 years of experience in 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 wellhead & x-mas tree.
After more than 20 years of development, thermal wellhead has formed a variety of products, used in many oilfields in the world.
- Steam injection and oil recovery dual tubing wellhead is applicable for continuous and intermittent thermal recovery of heavy oil well.

The main feature of the oil wellhead 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.
Steam injection and oil recovery dual tubing wellhead is applicable for continuous and intermittent thermal recovery of heavy oil well.
This structure oil wellhead improves steam injection efficiency and oil recovery efficiency.
The steam injection and oil recovery dual tubing wellhead 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 can avoid pressure leakage and reduce the occurrence of accidents.
