| Product Introduction |
 5-1/2 Inch BTC K55 oil casing China is still in the rapid development stage of urbanization and industrialization. It is expected that the average annual demand for oil in the next few years will increase by about 4%. The increasing demand for oil has promoted the continuous increase in the demand for oil drilling equipment in China. From the perspective of China's domestic regional distribution, the demand for tubing casing is no longer concentrated in the eastern region. From the perspective of the development of domestic oil and gas fields, the eastern oilfields such as Daqing, Liaohe, and Shengli were initially developed, and the western oilfields such as Sichuan and Xinjiang were later developed. The focus is on the trend of offshore oilfields. In addition, they will develop from land to tidal flats and from shallow to deep seas. AVIC Steel believes that coupled with the deeper and deeper drilling, the drilling conditions are becoming more and more complex, and the requirements for oil casing are bound to be higher and higher. |
