On the basis of the summary on the advantages of aluminum alloy drilling pipe, this paper introduced connection methods and interference fit for aluminum alloy drilling pipe and steel joint in new national standard. Some examples were given to illustrate the advantages for adopting aluminum alloy drilling pipe in deep wells, which can evidently decrease hook load, rotary torque and pumping pressure loss. Finally, the paper discussed application prospects of aluminum alloy drilling pipe in deep holes for geological exploration.
