Abstract:
Drill string element for installing in a drill string, in particular for horizontal or slant directional drilling (HDD or SDD), for the creation of a drill hole ( 100 ) along a drill path, in particular for laying a pipeline, comprising a tubular main body ( 11 ) having bilateral connecting elements ( 13, 15 ) for connecting the drill string element ( 10 ) to the drill string, wherein the drill string element ( 10 ) has an interior ( 22 ) through which a flushing medium for the flushing of the drill hole ( 100 ) and the evacuation of drill cuttings loosened by a drill head connected to the drill string is transportable, comprising at least one opening ( 23 ), connected to the interior ( 22 ), in a wall ( 16 ) of the main body ( 11 ), through which at least a part of the flushing medium flowing through the interior makes its way into an annular space ( 102 ) between drill hole wall ( 103 ) and main body ( 11 ), characterized in that on the outer wall ( 16 ), over the opening ( 23 ), is arranged at least one body ( 17 ), in which is disposed, at least in part, a flow channel ( 24 ), in that the flow channel ( 24 ) has at least one flow path and is fluidically connected to the opening ( 23 ) via an inlet opening ( 25 ), in that the flow channel ( 24 ), on its side facing away from the opening ( 23 ), has at least one outlet opening ( 28 ), and in that the clear cross section of the opening ( 23 ) and/or inlet opening ( 25 ) is smaller or larger than the clear cross section of the outlet opening ( 28 ).

Claim (Index 18):
The drill string element as claimed in  claim 16 , wherein the at least one further body is disposed on the tubular main body with the outside radius of the tubular main body enlarged in at least one section forming an eccentric, by which the drill string can be periodically raised from the drill hole wall in the course of the drilling.
