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 16):
A drill string element intended for placement in a horizontal directional drilling (HDD) drill string, the drill string intended for the creation of a drill hole along a drill path for laying a pipeline, the drill string element comprising:\n bilateral connecting elements for connecting the drill string element to the drill string; a tubular main body having a wall and an interior through which a flushing medium flushes the drill hole and evacuates drill cuttings loosened by a drill head connected to the drill string;\n wherein the wall of the tubular main body comprises at least one opening which is connected to the interior, and, at least a part of the flushing medium flowing through the interior passes through the opening into an annular space between drill hole wall and an exterior of the tubular main body; \n at least one further body disposed over the opening, comprising, at least in part, a flow channel, the flow channel comprising: at least one flow path with at least one inlet opening and at least one outlet opening,\n wherein the flow channel is fluidically connected to the opening via the at least one inlet opening; \n the at least one outlet opening is disposed in the further body on a side facing away from the opening; \n the at least on inlet opening and the at least one outlet opening have an open cross section; \n the open cross section of at least one of the opening or inlet opening is at least one of smaller or larger than the open cross section of the outlet opening; \n the outlet opening is disposed substantially axially to the center axis of the drill string element; \n wherein; the open cross section of the outlet opening and at least one of the opening or the inlet opening ( 25 ) are adjustable; at least two of the opening, the inlet opening, the inside the flow channel, or the outlet opening comprise at least one of a nozzle or an orifice plate, and at least one of the nozzle or orifice plate is changeable.
