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. China's domestic market share of oil pipe has more than 80%, and has become a net export products 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, it is expected that in the next few years, the average annual growth of oil demand will be about 4%. The increasing demand of oil has promoted the increasing demand of petroleum drilling equipment in china.
From the perspective of China's regional distribution, the demand for 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. In addition, the steel pipe is considered to be more and more deep, and the working condition of drilling is becoming more and more complex.
