The invention relates to a trace control method, in particular to a constant tool face angle drilling trace control method, and belongs to the technical field of downhole drilling. The two typical three-dimensional constant tool face angle borehole trajectory designing models of defining the target point position and defining the target point position and the target entry direction at the same time are established, a design constraint equation is rapidly and flexibly solved according to different design requirements, and therefore the design has universality and flexibility and theoretical foundations are provided for designing and control of the borehole trajectory.
