Research and Design of Wellbore Trajectory Control System in Complicated Geological Environment
CAI Zhen
Abstract：For the existing problems of wellbore trajectory control in the complex geological environment,the control idea of deviation vector applied to petroleum system is introduced into the process of geological drilling. By analyzing the trajectory control process of geological drilling,the concept of vector angle is put forward and used as the input of the controller. The algorithm of fuzzy control is used to establish the trajectory control model of drilling process. The trajectory control system and its fuzzy controller are designed by using the simulation software. The validity of fuzzy control is verified by comparing with the traditional PID control algorithm.
