Steam Injection and Oil Recovery Dual Tubing Wellhead
Sanjack has more than 40 years of experience in the production of wellheads and trees and valves. With advanced manufacturing and testing facilities, Sanjack can produce wellheads and trees in a wide range of pressure, material and specification grades. After more than 20 years of development, thermal wellhead has formed a variety of products, used in many oil fields around the world. Sanjack has the following types of thermal wellheads:
- Conventional steam injection wellhead
- Onshore thermal wellhead
- Single column double well thermal recovery wellhead
- Steam injection and oil production double pipe wellhead
- BOP steam injection and oil production integrated wellhead
- Geothermal wellhead
Steam injection and oil recovery dual tubing wellhead is applicable for continuous and intermittent thermal recovery of heavy oil well.
The main characteristic of wellhead is that under high temperature and high pressure, steam injection channel, oil production channel, casing annulus and external air are sealed and disconnected, so steam injection and oil production can be carried out simultaneously. This type of wellhead improves steam injection efficiency and oil recovery efficiency. Steam injection and oil production double pipe wellhead is equipped with pressure relief pipe, which can lead the overpressure into the casing pipe to relieve the pressure in the pipe and boost the pressure in the casing pipe. The wellhead can avoid pressure leakage and reduce accidents.
