Aluminum Alloy Drilling pipe
Compared to conventional steel drill pipe,aluminum alloy drill pipe has many advantages in weight,specific strength and anti-corrosion. In the condition of certain drill capacity,adopting aluminum drill pipe could get to the depth which steel pipe could not
reach.High reliability aluminum alloy drill pipe is developed by the new method of connecting to steel joints and high temperature
assembly technology,which makes it improve the fatigue resistance when working in deep well, inclined well and large displacement
horizontal well.Examples proves that high reliability aluminum drill pipe has excellent application prospect in deep well,directional inclined
well and horizontal well.
Advantages:
Light weight,1/3 of steel drill pipe.
H2S & CO2 corrosion resistance.
Flexible aluminum drill pipe has perfect fatigue resistance,its fatigue life exceeds wear life.
Aluminum drill pipe has non-magnetic characteristics,which is useful for magnetic logging,its available to install aluminum drill pipe with no steel joint in logging section.
Aluminum drill pipe has little frictional resistance with the wall of well,which can reduce the drill sticking.
In the condition of same hole curvature,the bending stress of aluminum drill pipe is far less than steel drill pipe,so its suitable for the drill of inclined well,small bending radius directional well and large displacement horizontal well.
Applications:
Deep well,ultra deep well,horizontal well,directional well and acid gas well.

Application Areas:
Mountain areas,desert and offshore exploration platform.

High Requirements for Material:
Super high tensile strength,elasticity,wear-resistance,high temperature resistance and stress corrosion resistance.
