Heat Resistance Casing and Tubing
Heavy oil exploitation accounts for a large proportion of oil resources exploitation, which spreads over more than 10 reservoir areas such as Liaohe, Shengi, Xinjang and Henan.
In recent years, oil and gas produced by steam stimulation technology is in the stage of high–cycle due to the decline of formation pressure. However, the tubing and casing of common API standard could not meet the requirements because of its low strength and easy deformation at high temperature.
Glory Tube develops a series of heat resistance tubing. heat resistance and high collapse strength casing with favorable mechanical properties and stability at high temperature, which are suitable for 300℃, 20 MPa steam pressure, to meet the demand of customers.
Uses
This series of products are suitable for thermal recovery of heavy oil.
