Conventional Steam injection and oil recovery 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 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

Conventional steam injection and oil recovery wellhead & x-mas tree is low pressure and high temperature oil and gas wellhead & x-mas tree, which is connected by a clamp or flange:

Clamped thermal recovery wellhead & x-mas tree:

Feature

1)Clamp type connection, easy to operate
2)Wedge gate valve, small size and light weight
3)The stem seal of valve is a high temperature resistant composite seal. The seal between valve plate and valve seat and the seal between valve body and valve seat are both metal seals. High temperature seal is reliable.

Flanged thermal recovery wellhead & x-mas tree:

Feature

1).Flange connection. The high temperature and high pressure seal in the connection is reliable.
2).The valve is a rising rod structure. There is a protective cover on the hand wheel to visually check the opening or closing of the valve. And it has the function of preventing sand and dust.
3)The surface of valve seat and valve plate is sprayed with cemented carbide. The seal between valve seat and valve body is high temperature resistant and non-metal seal with good performance.
4).The stem seal is a high temperature resistant composite seal. No leakage at high temperature and high pressure. After thermal calculation, the pressure and load components are safe and reliable at high temperature.
