Abstract The invention discloses a method and equipment used to control the change of angle remotely. The said angle means the bend angle of curved shell structure of dynamic drill tool that is used in the well boring process of controlled directional well for oil and geology exploratory development. The equipoment is composed of motion control unit, adjusting mechanism for bending angle of structure and power actuating system. The invention gives the adjusting capability to the guiding drill tool on underneath of well, therefor, increase control accuracy of well orbit and lower the cost of drilling.
