　　Tubing is divided into flat tubing(NU),thickened tubing(EU)and integral joint tubing(IJ).Flat tubing means that the pipe end is directly threaded and provided with coupling without thickening.Thickened tubing means that both ends are externally thickened before threading and coupling.Integral joint oil pipe refers to that one end passes through internal thickening external thread,and the other end passes through external thickening internal thread,and is directly connected without coupling.

 

　　The role of tubing:oil and gas extraction:after the oil and gas well is drilled and cemented,tubing is placed in the reservoir casing to extract oil and gas to the ground.Water injection:when the downhole pressure is not enough,inject water into the well through the tubing.Steam injection:in the process of heavy oil thermal recovery,heat insulation tubing shall be used to input steam into the well.Acidizing and fracturing:in order to improve the production of oil and gas wells in the late period of well drilling,it is necessary to input acidizing and fracturing media or solids into the oil and gas reservoirs.The media or solids are transported through the tubing.
