Case:
The core application of J55 oil tubing (API 5CT standard) focuses on the construction of tubing columns for shallow to medium-shallow oil wells, and it mainly undertakes two types of key functions: wellbore structural support and oil recovery process implementation.
In China, the pipes has been deeply involved in national key projects such as Daqing Oilfield Production Stabilization Project and Tarim Oilfield Marginal Block Development, etc. In international supply, we has successfully supplied bulk tubing for Kumkol Oilfield Shallow Development in Kazakhstan and Sumatra Block Low-Pressure Oil Wells in Indonesia, which have supported the energy development in Central Asia and Southeast Asia region.
