Oil casing development history

The history of oil casing development. After nearly 20 years of hard work, China's oil casing production has gone from scratch, from low price to high price, from low steel grade to API series products to special demand non-API products, from quantity to quality are close The level of foreign oil casing products. The domestic market share of China's oil well pipes has exceeded 80%, and has been a net export product for many years.
In 2011, China's crude oil output reached 204 million tons, an increase of 0.32% compared with 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 development of urbanization and industrialization. It is expected that oil demand will grow at an average annual rate of about 4% in the next few years. The continuous increase in oil demand has promoted the rising demand for oil drilling equipment in China.
From the perspective of China's domestic distribution, the demand for oil casings is no longer concentrated in the eastern region. From the trend of domestic oil and gas field development, from the initial development of Daqing, Liaohe, Shengli and other eastern oil fields, it will turn to the development of western oil fields such as Sichuan and Xinjiang, paying attention to the trend of offshore oil fields, and will also develop from land to tidal flats and from shallow seas to deep seas. Drilling depth is getting deeper and deeper, drilling work conditions are becoming more and more complex, and the requirements for oil casings are bound to become higher and higher.
