Definitions
- the invention relates to an installation kit for drill pipes of a pipe string, in particular a drill string, a drill pipe of a pipe string, in particular a drill string, a pipe string, in particular a drill string, and a method for producing or finishing a drill pipe.
- the same also applies to the subsequent petroleum, gas or hot water production, to which the invention also relates.
- the drilling industry therefore needs a system that enables electrical energy transmission and/or electrical or optical data transmission during the drilling process or production process.
- Such a system should be as independent as possible of the structural design of the drill pipes, so that both new drill pipes and existing drill pipes can be equipped with them.
- the installation kit according to the invention has a first end and a second end which are connected to one another by means of at least one connecting line.
- One of the two ends is placed in a pin of the drill pipe and the other end is placed in a box of the drill pipe.
- a seal is disposed at the first end and/or the second end.
- a sealing element that seals the respective end from the pin or the box is arranged on the peripheral surface of each end.
- all seals, sealing elements and seals are designed in such a way that they comply with the safety regulations in connection with electricity on drilling rigs and therefore no further safety measures have to be taken.
- the connecting line between the two ends could itself be a correspondingly protected electrical, optical or hydraulic line, but is preferably a tube in which an electrical or optical line is or can be accommodated.
- empty piping is also possible.
- the connecting line and in particular the tube is connected at both ends to a respective line channel in the ends.
- the connecting line or the electrical or optical line arranged in the connecting line can be guided reliably to a connection point between the ends of the installation kits or drill pipes that adjoin one another.
- one end of the installation kit has a socket and the other end has a spigot end, and a seal is arranged between the socket and the spigot end is.
- the spigot end can have a first and a second longitudinal section, the first longitudinal section having a larger outer diameter than the second longitudinal section, the at least one connecting line being connected to the line duct on the first longitudinal section and the line duct being connected to a Shoulder opens out between the first and the second longitudinal section.
- the duct opens out on an end face of the sleeve, and the at least one connecting line is connected to the duct on a side of the sleeve opposite the end face.
- the space thus formed between the spigot end, the socket and a drill pipe can be used to accommodate at least one electrical, optical, hydraulic or radio-technical device.
- electrical and/or optical devices such as measuring devices, as well as connections or couplings for connecting the electrical and/or optical lines from one installation kit to the next can be installed in this space.
- Fig. 1 shows a drill pipe
- Fig. 2 shows an embodiment of a kit according to the invention
- Fig. 3 shows the ends of the kit of Fig. 2 on an enlarged scale and in section
- 4 shows the installation set according to FIG. 2 installed in the drill pipe of FIG. 1 in a partial longitudinal section
- FIG. 5 shows the installed installation set from FIG. 4 with further details
- FIG. 6 shows the connection area of two drill pipes of a drill string with an installation set according to the invention in a partial section.
- FIG. 1 shows an embodiment of a drill pipe 6 which is conventional per se in the prior art and which has been modified according to the invention. It goes without saying that the drill pipe can also be constructed differently, unless reference is made below to specific features of the drill pipe 6 as absolutely necessary features.
- the drill pipe 6 has a pipe body 2, at one end of which a pin 3 and at the other end of which a box 1 is arranged.
- the box 1 and the pin 3 are welded to the tubular body 2 .
- An external thread or trunnion thread is attached to the pin 3 and an internal thread or socket thread in the box 1, the two threads preferably being conical threads.
- the inside of the drill pipe 6 is open throughout, so that when the drill pipes 6 are screwed together, a channel 8 is formed through which, for example, flushing fluid can be conveyed from the drilling rig on the surface to the drill head.
- the drill pipe 6 is not a drill string but a pipe string for the production of oil, gas or water, for example, it can be conveyed upwards through the channel 8 inside the drill pipe 6 .
- the two ends 17 , 18 are connected by means of two connecting lines 13 .
- the connecting lines 13 are tightly connected, for example by means of a seal 37, to line ducts 16 in the ends 17, 18.
- one end 17 has a socket 19 and the other end 18 has a spigot end 20 .
- the socket 19 and spigot 20 are compatible and nest together so that a connection between two adjacent kits 7 can be made.
- the sleeve 19 has an inner wall area 21 and the spigot end 20 has an outer wall area 22 .
- the inner wall area 21 and the outer wall area 22 are preferably cylindrical, but can also be conical or concave/convex.
- a sealing ring 23 is arranged on the outer wall area 22 of the spigot end 20 .
- the seal is not a separate part like a sealing ring, but is formed by two sealing surfaces arranged on the sleeve 19 and on the spigot end 20, which abut each other under pressure, whereby the seal through the sealing surfaces the socket 19 and the spigot end 20 is produced.
- the line channel 16 leads from the connecting line 13 through the interior of the sleeve 19 to an end face 24 which is opposite the connecting line 13 .
- the spigot end 20 has a first longitudinal portion 25 and a second longitudinal portion 26, both of which are substantially have a cylindrical shape.
- the first longitudinal section 25 has a larger outside diameter than the second longitudinal section 26 .
- a shoulder 27 is formed at the transition between the first longitudinal section 25 and the second longitudinal section 26 .
- the line channel 16 leads from the connecting line 13 through the interior of the spigot end 20 to the shoulder 27 and opens out there.
- the distance between the mouth of the line duct 16 on the end face 24 of the sleeve 19 and the mouth of the line duct 16 on the shoulder 27 of the spigot end 20 from a longitudinal axis of the installation kit 7 is preferably essentially the same, although different distances are of course also possible.
- the shoulder 27 of the spigot 20 and the face 24 of the sleeve 19 are spaced apart sufficiently to form a space 15 in which electrical and/or optical components can be placed.
- These components can be, for example, sensors and electrical or electromagnetic connections or couplings, via which electrical energy transmission and/or electrical or optical data transmission can take place when the sleeve 19 and the spigot end 20 are plugged together.
- the device described in EP 2440737 B1 for connecting electrical lines can be installed in space 15 in order to connect electrical lines routed through connecting lines 13 and line ducts 16 to connecting drill pipes 6 or installation kits 7 to one another.
- sealing sleeves 9, 14 which are integrated into the socket 19 and the spigot end 20 or connected tightly to them.
- the sealing sleeves 9, 14 have a peripheral surface 11 with a cylindrical shape, on which a sealing element 28 is arranged.
- a clamping device 29 which essentially consists of two sleeves 10, 12 which can be displaced relative to one another in the axial direction.
- Each of the sleeves 10, 12 has a wedge surface 31, 32 on the side facing the other sleeve 10, 12. Between The two sleeves 10, 12 are regularly distributed around the circumference wedges 33 which have the wedge surfaces 31, 32 associated wedge surfaces.
- the sleeves 10, 12 can be braced against one another by means of screws 34, as a result of which the wedges 33 are displaced radially outwards and the clamping device 29 is clamped in the pin 3 and in the box 1, respectively.
- the clamping devices 29, more precisely their sleeve 10 arranged on the side of the socket 19 or the spigot end 20, also have resilient projections 35 which can snap into recesses 36 in the socket 19 or the spigot end 20.
- An installation kit 7 according to the invention can be assembled, for example, by first pushing a clamping device 29 into the pin 3 and into the box 1 of a drill pipe 6 .
- the connecting lines 13 are pushed into bores 38 , 39 provided in the sleeves 10 , 12 until they protrude beyond the sleeve 10 . If necessary, the
- Clamping devices 29 are then pulled slightly apart again in order to tension the connecting lines 13 .
- the electrical and/or optical lines can then be pushed through the connecting lines 13 and the line channels 16 in the sleeve 19 and the spigot end 20 provided. Then the sleeve 19 and the spigot end 20 are pushed into the pin 3 and the sleeve 1 until the projections 35 engage in the recesses 36, whereby the two ends 17, 18 are firmly mounted in the drill pipe 6.
- the space 15 is created by the seal 23 between the socket 19 and the spigot end 20, the sealing elements 28 between the peripheral surface 11 of each end 17, 18 and the pin 3 and the box 1, as well as the sealing at the screw connection between the pin 3 and the box 1 of adjoining drill pipes 6 to the environment, ie to the area outside the drill pipes 6 on the one hand and the channel 8 inside the drill pipes 6 on the other hand, sealed out remains to the Line channels 16 out but open. Since the line channels 16 are in turn well sealed with respect to the connecting line(s) 13, there is no critical connection or leakage from the environment here either.
- the installation kit according to the invention can be used not only in the production of new drill pipes, but also for retrofitting older drill pipes that have been in operation for a long time.
- the installation kit 7 it is also possible to rework the threads on the pin 3 and in the box 1, which is necessary at regular intervals due to wear or damage to the threads. In this case, it is only necessary to remove the installation kit 7 from a drill pipe 6, rework the threads and reinsert the installation kit 7 into the drill pipe 6. Any necessary shortening of the connecting line 13 between the two ends 17, 18 due to the shortening of the length of the drill pipe 6 can also be carried out easily.
