Special aluminum alloys appear to be promising materials for manufacture of high-strength light-alloy drill
pipes (HSLADP) that can be used in areas with a severe climate and challenging geology. The effect of using
light-alloy drill pipes (LADP) depends directly on the properties of the aluminum alloys from which such
pipes are made. As the wells become deeper and horizontal wellbores get longer, use of LADPs becomes
more relevant. Since light-alloy pipes are 2.8 times softer than steel pipes, LADPs offer the same performance
as steel drill pipes of the lowest strength grade even in the case of rotary drilling. The materials from which
such pipes are made have a number of unique advantages: extra light weight in the drill mud, allowing the
coefficient of sliding friction between the pipe surface and the borehole wall to be reduced; high corrosion
resistance in aggressive media with A high concentration of hydrogen sulfide and carbon dioxide; and high
magnetic inductive capacity that allows LADPs to be used as a housing for MWD (measurement while drilling)
and LWD (logging while drilling) telemetry systems during well-drilling operations. This study suggests
methods for industrial production of submicrocrystalline (SMC) structure in aluminum alloys with the help
of severe plastic deformation. Through the example of model aluminum-lithium alloys 1420 (Al-Mg-Li-Zr)
and 1460 (Al-Сu-Li-Zr), the researchers demonstrate that SMC structure helps significantly increase resistance
to wear and reduce the rate of corrosion depending on the pH value. The research team also states that
severe plastic deformation methods may be used to develop highly promising technologies for manufacture
