The deviation correction method needs to be verified by experiments repeatedly before it can be applied to practical projects. It will take much time and money to conduct field testing before the development of algorithm has been completed. So it is very necessary to develop the engineering realization method of deviation correction control . In this paper， with the realization of deviation correction control in geological drilling as the research subject， the description of the actual correction process and the objectives of correction control are given. The problems with the model predictive control are summarized， and the correction control methods under different correction conditions are described based on the author’s early theoretical research. A directional drilling correction control system is developed to integrate the correction control algorithm. Finally， experiments are designed to verify the engineering applicability of the correction control algorithm. The experimental results show that the proposed control method can be effectively applied to the actual correction process， and can solve various correction tasks.
