Definitions

  • the invention relates to a drill string element for installation in a drill string for creating a borehole along a drill route, in particular for laying a pipeline, with a tubular base body with connecting elements on both sides for connecting the drill string element to the drill string, the drill string element having an interior through which a Flushing medium for flushing the borehole and the removal of cuttings loosened through a drill head connected to the drill string can be transported, with at least one opening connected to the interior in a wall of the base body, through which at least part of the flushing medium flowing through the interior into one Annulus between the borehole wall and the base body, wherein at least one body is arranged on the outer wall above the opening, in which at least partially a flow channel is arranged, the flow channel at least one flow channel g and is fluidly connected to the opening via an inlet opening, the flow channel on its side facing away from the opening at least one outlet opening, and the clear cross section of the opening and / or inlet opening being smaller or larger than the clear cross section of the outlet opening, wherein
  • a drilling and laying method (horizontal directional drilling) is known in which a pilot hole with a drill head and a drill string is made from a starting point to a target point for trenchless laying of a pipeline under an obstacle along a predetermined drilling line.
  • the drill head is driven by turning the drill string.
  • a scraper is then placed on the pilot drill string on the target side attached, which is connected to the pipeline to be laid.
  • the reamer is driven by turning the drill string.
  • the reamer is advanced while the pipeline is being pulled in by pulling out the pilot drill string.
  • the pilot drill head When pilot drilling with the HDD process, the pilot drill head is pushed using boring bars and pushed along the planned route. A drilling suspension is pumped to the pilot drill head through an opening through the drill pipe. There, the cuttings mined by the pilot drilling head mix with the drilling suspension. This suspension then flows with the cuttings through the drilled borehole back to the starting point or entry point of the borehole. Since the diameter of the drill head is not significantly larger than the outside diameter of the boring bars, there is an annular space between the borehole and the boring bar. A flow forms in this annulus, with which the cuttings are conveyed out of the borehole.
  • drilling In addition to the environmental aspect of an undefined irrigation outlet, drilling must also be interrupted because controlled removal of the cuttings is no longer possible. A so-called rinsing blow-out can only be done with great effort repair again by adding additives to the drilling fluid or cementing the blow-out point.
  • critical mud pressures are usually calculated in advance by superimposing existing geological data with a pressure calculation. The maximum values must not be exceeded. The pressure can be measured and monitored using pressure sensors behind the drill head.
  • EP 0171335 A1 discloses a drill string element for vertical drilling in the petroleum / natural gas sector.
  • the drill string element has a flow channel with an inlet and a nozzle in the outlet, the nozzle being designed to be exchangeable.
  • a fixed volume flow of flushing, which flows through the flow channel, is provided at the nozzle, which experiences a speed increase through the nozzle.
  • a desired aggressive flushing jet is emitted vertically upwards, with the aim of providing movement in poorly / not flowed through zones of the bore above the outlet.
  • the interchangeability of the nozzle is used for replacement when the degree of wear of the nozzle is reached for repair purposes.
  • the body also acts as a stabilizer in the borehole to center the drill string with respect to the borehole walls.
  • US 2634101 A discloses a drill string element for vertical drilling in the petroleum / natural gas area directly behind the drill head.
  • the drill string element has an element with a flow channel with an inlet and an outlet, the element being designed to be exchangeable.
  • a fixed volume flow of flushing, which flows through the flow channel, is delivered at the outlet.
  • a flushing jet is emitted vertically upwards behind the drill head. The interchangeability of the element is used for replacement when the element has reached a degree of wear for repair purposes.
  • WO 9604458 A1 discloses a drill string element for vertical drilling in the petroleum / natural gas area directly behind the drill head.
  • the drill string element has an element with a flow channel with an inlet and an outlet. Flush that flows through the flow channel is released at the outlet when a certain purge pressure is inside of the drill string is exceeded by opening a valve. The release takes place radially horizontally towards the borehole wall.
  • the clear cross sections are also the same.
  • US 20040011561 A1 also discloses a drill string element for vertical drilling in the petroleum / natural gas field.
  • the drill string element serves, in the reverse arrangement, to receive flushing from the ring space into the drill string when flushing over the annular space and removing the cuttings over the drill string.
  • US 5407020 A discloses an apparatus and method for removing cuttings from vertical bores. The cuttings are removed pneumatically.
  • the object of the invention is to provide a drill string element and a drill string with the same, with which it becomes possible to keep the pressure in the annulus below the calculated limits or to keep the pressures prevailing in the annulus or drill string as low as possible.
  • deposited cuttings should also be brought back into the flow or the cuttings should be prevented from settling.
  • the drill string is a drill string for horizontal directional drilling (HDD), that the drill route extends essentially horizontally from a starting point to a target point, that the clear cross section of the opening or the entry opening and the outlet opening is adjustable such that the setting is carried out by arranging at least one nozzle and / or orifice in at least two of the opening, the inlet opening, within the flow channel and / or in the outlet opening, the at least two nozzles and / or Orifices are designed to be exchangeable, and the nozzle and / or orifice plate is selected so that at the point of installation of the drill string element in the drill string in the borehole, the flushing medium can be dispensed into the annulus with a predetermined volume flow and / or pressure, the volume flow and / or pressure in the annulus depending on geological conditions it is set in the upcoming mountains, and that the at least one body extends on the base body, so that the outer radius of the base body increases in sections and there is an eccentric through

  • the desired parameters of the flushing medium can be adjusted / set particularly easily.
  • the nozzle (s) By changing the nozzle (s), the parameters desired at the operating point of the drill string element can be set particularly easily. As a result, different pressure levels within the drill pipe depending on the drill length are compensated for in a particularly simple manner.
  • the outlet opening is arranged essentially axially to the central axis of the drill string element, the flushing medium is dispensed along the drill string, which leads to movement of the cuttings, in particular if it has settled. Furthermore, widening of the borehole is avoided by direct action of the flushing medium that is emitted on the borehole wall.
  • the at least one body preferably the one body, extends on the base body, so that the outer radius of the base body increases in sections and there is an eccentric through which the drill string can be temporarily raised during drilling.
  • the eccentrically designed drill string element causes the drill string to rise with every revolution. By lifting the flow cross-section in the upper area of the borehole is reduced, which leads to the drilling fluid flowing along the bottom of the borehole. As a result, deposited cuttings are returned to the drilling fluid.
  • the outlet opening is arranged in a rear side surface of the body.
  • the outlet opening is advantageously arranged on the rear side surface in such a way that the drilling suspension exiting at the outlet opening, which has been taken up by a receiving and transport surface on the body and leaves it at the rear end, is carried along by the drilling suspension exiting there and thus the general flow fed back to the drilling suspension in the annulus and transported out of the borehole in the direction of flow.
