After nearly 20 years of efforts, China's oil production from scratch, from the low price to high price, from the low level to the API series products to the special needs of non API products, from quantity to quality has been close to the level of foreign oil casing products. China's oil well pipe domestic market share has exceeded 80%, and has been for many years to become a net exporter of products.

According to the 2013-2017 China oil casing industry sales demand and investment forecast analysis report, 2011, China's crude oil production reached 2.04 tons, compared with the same period in 2010 increased by 102531000000; natural gas production reached 0.32% cubic meters, an increase of 6.9%, a record high. China is still in the stage of urbanization, industrialization and rapid development, the oil demand is expected to grow at an average annual rate of about 4% in the next few years. Oil demand continues to promote the growth of China's oil drilling equipment demand continues to rise.

According to the regional distribution of our country, the demand of oil casing is no longer concentrated in the eastern part of China. From the development trend of domestic oil and gas fields, from the initial development of the Daqing, Liaohe, Shengli and other Eastern oil fields to Sichuan, Xinjiang and other Western oil field development, focus on the trend of offshore oil field, in addition, from the land to the tidal flat, from the shallow to the deep sea development. In the air tube, the depth of drilling and the drilling operation are becoming more and more deep, and the working condition of the drilling pipe is becoming more and more complicated.
