Research on Automatic Rectifying-Deviation Technique for Drilling Oil Well

The paper discussed an automatic rectifying- deviation system, it is a downhole closed-loop automatic device based on SCM (Single Chip Micyoco) control, whose information receive, treatment and control are absolutely accomplished under well, it represents the development direction of rectifying- deviation technology at home and abroad, with a higher level of automation. The paper mainly described the components of drilling-system and the spatial position of drill trajectory, designed the structure of drill's automatic rectifying-deviation system, determined control principles, control methods and software design. Finally, through computer simulation to verify it.
