1. Classification of tubing

Tubing is divided into flat tubing (NU), thickened tubing (EU) and integral tubing.Flat tubing refers to the pipe ends are threaded directly and with hoop.Thickening tubing refers to the two ends of tubing after external thickening, and then screw with hoop.Integral joint tubing refers to one end of the inner thick car outside the thread, the other end of the outer thick car inside the thread, direct connection without collar.

2. Function of tubing

Pipe and steam extraction: after the well is drilled and fixed, put tubing in the Oil Casing to extract oil and gas to the ground.

Injection: when downhole pressure is insufficient, inject water into the well through the pipeline.

Pipe and steam injection: in the thermal recovery process of heavy oil, heat insulation tubing shall be used to input steam underground.

Exposure, acidification and fracturing: at the later stage of well drilling or in order to improve the production of oil and gas Wells, it is necessary to input acidification and fracturing medium or solidification material to the oil and gas layer, which is transported through pipelines.

3. The steel grade of the tubing

Tubing steels are: H40, J55, N80, L80, C90, T95, P110.

N80 is divided into n80-1 and N80Q. The similarity between them is the same in tensile performance, while the difference between them is the difference between delivery state and impact performance. When n80-1 is delivered in normal state or when the final rolling temperature is greater than the critical temperature Ar3 and the tension is reduced and it passes air cooling, it can be replaced by hot rolling.N80Q must undergo tempering (quenching and tempering) heat treatment, the impact energy shall conform to API 5CT regulations and shall be subject to non-destructive testing.

L80 is divided into l80-1, l80-9cr and l80-13cr.Their mechanical properties and delivery state are the same.The difference lies in the application, production difficulty and price. L80-1 is a common type, while l80-9cr and l80-13cr are both highly corrosion-resistant tubing, which are difficult to produce and expensive, and are commonly used in heavily corroded Wells.
