History of the development of oil casing

After nearly 20 years of efforts, China's oil casing production from scratch, from low price to high price, from the low level to API steel products to the special needs of non API products, from quantity to quality has been close to the level of the products of foreign oil casing. The domestic market share of China's oil well tube has been more than 80%, and has become a net export product for many years.
According to the analysis of the "report" statistics, 2011 sales forecast demand and investment China oil casing industry 2013-2017 years, China's crude oil output reached 2.04 tons, an increase of 0.32% compared with the same period of 2010; natural gas production reached 102 billion 531 million cubic meters, an increase of 6.9%, a record high. China is still in the stage of rapid development of urbanization and industrialization, the oil demand is expected to grow by about 4% annually in the next few years. Oil demand continues to promote the growth of China's oil drilling equipment demand continues to rise.
From the regional distribution of our country, the demand of oil casing is no longer concentrated in the eastern region. From the domestic oil and gas field development trend, from the eastern part of Daqing, originally developed in Liaohe and Shengli Oilfield later turned to Sichuan, Xinjiang and other Western oil field development, focus on offshore oilfield trend will also be from the land to the beach, from the shallow to the deep sea development. Aircraft steel pipe that combined with the depth of the drilling, drilling work is becoming increasingly complex, the requirements of the oil casing is bound to become more and more high.
