The invention mainly belongs to the technical field of rotary guide systems, and particularly relates to a full-rotation hydraulic inward-pushing-type high-build-up-rate rotation guide tool. The full-rotation hydraulic inward-pushing-type high-build-up-rate rotation guide tool adopts a hydraulic system driven by a turbine and a generator set to convert the energy of the pressure mud into the hydraulic energy. By adopting the hydraulic system driven by the turbine and the generator set, the power is provided for a piston through the hydraulic mode, so that the lateral force obtained by a drillbit is larger. Meanwhile, the hinged mode is adopted, so that the optimal steering capability is achieved. As a result, the high build-up rate is easier to achieve. The hydraulic piston pushes againstthe inner wall of a lower rotating sleeve instead of the wall of a well, so that the abrasion can be reduced. At the same time, only one set of pushing piston assemblies is pushed out at the same moment, so that the unnecessary work is reduced. The service life of the piston is prolonged.
