Abstract

The principle of a tilting sleeve for steering the bore hole has the advantage of an enclosed force flow in the sleeve. In contrast to the rip activated steering principles the actuators are inside the tool body. The tilt of the sleeve can be generated by an eccentric part in the tool or by dynamically activated pistons. This principle gives the opportunity to realize an internal driven push-the-bit principle.
