Title: Directional impact drilling
IPC: E21B7/08
Filed: 1998-02-09
Granted: 2002-08-26
Abstract: The method of directional impact drilling is characterised by the use of impact drilling crowns with suitable asymmetrical distribution of the hard metal pins on the crown body and the synchronous variation of the shift angle with the rotation of the drilling crown.For deflecting the bore from its natural direction, the shift angle is changed synchronously with the rotations of the drilling crown such that an increased removal of material takes place in a given sector of the borehole floor.The one-sided removal effects an oblique position of the borehole floor in relation to the borehole axis and thereby the desired change of direction of boring in the natural course of events.<IMAGE>
