With a brief description about the external structure, internal composition and working principle of Power Drive Xceed rotary steerable system, this paper compared PD Xceed system with mud motor in terms of safety and timeliness. By the application of PD Xceed rotary steerable system in Bohai Oilfield, the analysis is made on the trajectory control, ROP and continuous deviation, the using pattern of commonly used horizontal well mud motor drilling tool and Power Drive Xceed rotary steerable system are obtained, which can be the experience reference to the application in other areas.
