Development History of OCTG Petroleum Casing
After nearly 20 years of hard work, China OCTG casing production has grown from scratch, from low price to high price, from low steel grades to API series products to non-API products with special needs, both quantity and quality are close to international OCTG casings product level. The China domestic market share of China OCTG has exceeded 80%, and it has been a net export product for many years.
In 2011, China's crude oil production reached 204 million tons, an increase of 0.32% over the same period in 2010; natural gas production reached 102.531 billion cubic meters, a year-on-year increase of 6.9%, a record high. China is still in the stage of rapid urbanization and industrialization. Oil demand is expected to grow at an average annual rate of around 4% in the next few years. Continued growth in oil demand has boosted demand for oil drilling equipment in China.
From the perspective of China's domestic distribution, the demand for oil casing is no longer concentrated in the eastern region. From the perspective of the development trend of domestic oil and gas fields, from the initial development of eastern oil fields such as Daqing, Liaohe, and Shengli to the development of western oil fields such as Sichuan and Xinjiang, paying attention to the trend of offshore oil fields, it will also develop from land to tidal flats and from shallow seas to deep seas. The drilling depth is getting deeper and deeper, the drilling conditions are getting more and more complicated, and the requirements for the oil casing are bound to be higher and higher.
