Embodiment Construction

[0049] 1 and 2 show a first embodiment of a wet drilling tool 10 according to the invention. The wet drilling tool 10 has a cylindrical casing 15, at the lower end of which a core bit 8 is arranged, where a removal area 17 is formed. In this exemplary embodiment, the core bit 8 has five roller cone bits 18 which are arranged in a ring-shaped manner in the core bit 8 .

[0050] The sleeve 15 terminates at its top face with an annular cover plate 11 . A dome 20 is provided in the center of the annular cover plate 11 . The dome 20 is cylindrical and penetrates at its lower part through the cover plate 11 into the inner region 3 of the wet drilling tool 10 . Arranged above the dome 20 is a rod connection 28 for a rotational connection to a drill rod, not shown.

[0051] Above the cover plate 11 is provided a collection container 6 for receiving the generated cuttings or fines. The collection container 6 is delimited by the cover plate 11 , the dome 20 and the cylindrical exten...

Abstract

The invention relates to a method for sinking a borehole in the ground, in which a wet boring tool with a removal area for producing or advancing a borehole is used, the borehole is at least partly filled with a fluid and in the borehole is formed a filling area and the removal area is at least partly washed round by a fluid flow, which conveys the bore smalls produced at the removal area to a collecting container located in the borehole. The method according to the invention is characterized in that the wet boring tool has a pumping mechanism through which fluid from the filling area is made to flow and conveys bore smalls produced into the collecting container. The invention also relates to a wet boring tool and to a boring plant.

Description

technical field [0001] The invention relates to a wet drilling tool comprising: a casing, below which a core bit is arranged, above which a cover plate with at least one channel arrangement serving as a fluid channel is arranged, the cover A plate and casing surround the inner region; a collection container for containing the drill cuttings produced, which is placed above the cover plate; and a pumping mechanism by which fluid from the wellbore filling region can flow, thereby The resulting drill cuttings are conveyed into a collection container, wherein the channel means is provided with a valve which allows fluid to flow into the inner region via the channel means and blocks the channel means when the fluid flows in the reverse direction. The invention also relates to a method for excavating a wellbore in the ground, wherein the wellbore is excavated or drilled using a wet drilling tool with a removed zone, a fluid is used to at least partially fill the borehole and form a p...
