The utility model provides a large-power high-speed high-efficiency turbine drilling tool stator-and-rotor combination part, and belongs to petroleum drilling industries. In order to resolve the problems that an existing low-speed turbine drilling tool is limited in carried drill type, multiple in stage, relatively low in efficiency, and the like, a stator blade plate and a rotor blade plate constitute a stage, the degree of reaction of the stage is less than 0.5, ten stages are successively sleeved on a shaft from top to bottom to constitute a turbine drilling tool power section, and the ten stages are matched in a pressed mode through end faces, a shell is sleeved on the outside of the ten stages. Molded lines of a stator blade and a rotor blade are built through sample band curves, the sample band curve of the rotor blade is shaped like the left side of a Chinese character 'ren', and the sample band curve of the stator blade is shaped like the right side of the Chinese character 'ren'.
