Special petroleum pipes are mainly used for oil and gas well drilling and oil and gas transportation.It includes oil drill pipes, special petroleum pipes and oil production pipes.Oil drill pipes are mainly used to connect drill collars and drill bits to transmit drilling power.
Special petroleum pipes are mainly used for oil and gas well drilling and oil and gas transportation.It includes oil drill pipes, special petroleum pipes and oil production pipes.Oil drill pipes are mainly used to connect drill collars and drill bits to transmit drilling power.Casing is mainly used to support the well wall during and after drilling to ensure the normal operation of the entire well during and after drilling.Tubing is mainly used to transport oil and gas from the bottom of the oil well to the ground.Oil well casing is the lifeline to maintain the operation of oil wells.Due to different geological conditions and complex downhole stress states, the combined effects of tensile, compressive, bending and torsional stresses on the pipe body put forward higher requirements for the quality of the casing itself.Once the casing itself is damaged for some reason, the output of the entire oil well may be reduced or even scrapped.
After nearly 20 years of hard work, the production of special petroleum pipes in our country has been from scratch, from low prices to high prices, from low steel grades to API series products, to non-API products with special needs, from quantity to quality, it is close to the level of foreign special petroleum pipes.China's domestic market share of oil well pipes has exceeded 80%, and it has become a net export product for many consecutive 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, an increase of 6.9% year-on-year, a record high.China is still in the stage of rapid urbanization and industrialization, and oil demand is expected to grow by about 4% per year in the next few years.The increase in oil demand has driven the increase in demand for oil drilling and production equipment in China.According to China's regional distribution, the demand for oil and casing is no longer concentrated in the eastern region.Judging from 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, we will pay attention to the development trend of offshore oil fields.In addition, we will also develop from land to beaches, from shallow seas to deep seas.In addition, the drilling depth is getting deeper and deeper, and the drilling situation is getting more and more complex, so the requirements for oil and casing will inevitably get higher and higher.
