Several methods of orbit design are discussed. Combined with the characteristics of sidetrack horizontal well trajectory control technology, a mathematical model of 3D optimization design of sidetrack horizontal well trajectory was established based on mathematical optimization theory. The model takes the shortest curve segment length as the objective function and quantitatively considers the main factors affecting orbit design and control. Theoretical analysis and verification of more than 10 wells show that compared with the conventional orbit design method, this model truly reflects the control law of sidetrack horizontal well trajectory control, improves the scientific design of orbit, avoids the shortcoming of repeated adjustment design, Greatly simplifies the orbit of the three-dimensional design process. In addition, the model has the function of adjustable target accuracy and precise target localization
