Definitions
- the invention relates to a device for connecting electrical lines to be screwed together, substantially tubular connecting elements of drill pipes.
- drilling rigs are sometimes using simple steel tubes without cabling.
- the tubes are bolted at regular intervals (e.g., 9 meters).
- mud flushing fluid
- One of these functions in the prior art is the transmission of data by means of pressure pulses. Since this communication is very slow (e.g., 10 baud), more and more methods have been sought which use other transmission mechanisms (sonar, ground currents, etc.).
- the most efficient solutions have been presented, which are connected to a wiring of the drill string (electricity, light, etc.). Once the drill pipe is connected by electrical cables or conductive layers, high speed data transmission is possible.
- Steel pipes must be manufactured or retrofitted with heat-resistant, mud-resistant, pressure-resistant cables without affecting the load-bearing capacity of the drill string and hindering the personnel when screwing the pipes.
- the electrical connection must be reliable, simple and robust when the pipes are mechanically connected (rotating movement).
- the biggest challenge in getting an electrical connection which can transmit power and / or data, is the screw movement during the screwing process of the individual drill pipe (pipes).
- the drilling process due to high pollution and liquids of all kinds, represents a harsh environment. This challenge is to be overcome in order to develop a successful, operational system.
- a first electrical contact element is fixedly arranged on a connecting element and that on the other connecting element, a second electrical contact element in the direction of rotation of the connecting element is slidably disposed.
- the construction solves the problem that during the screwing of the two connecting elements, two components of movement occur, namely one in the circumferential direction and one in the axial direction of the connecting elements. Due to the fact that one of the two contact element is movable in the circumferential direction, it may rotate in the production of electrical or galvanic connections between the two contact element with the other connecting element, so that the two connecting elements are connected to each other only via the axial movement component have to.
- the movable contact element is arranged on a rotatably arranged on the connecting element ring, wherein the ring is preferably an outer ring of a slip ring.
- Slip rings are proven and robust components in electrical engineering, which can also be used in the present case to compensate for the rotating movement component during the connection of the two connecting elements.
- the proposed solution is suitable for data transmission in the drill string based on cabled pipes (e.g., steel or CFRP pipes) whose wiring is galvanically connected to the pipe ends.
- cabled pipes e.g., steel or CFRP pipes
- the wiring can be done with a two-wire, heat-resistant power cable, which is laid in a protective tube (chemical resistance). On the surface, both electrical energy and data can be fed into this cable. In the case of the rotating drill string this is done with slip rings. In the pipe, this cable is routed to a connection element, which produces a good conductive connection to the next pipe.
- DC voltage in the mains voltage range can preferably be used for the supply of energy.
- the adaptation to all possible supply networks takes place once before the feed-in.
- a carrier frequency system is connected to the electrical lines.
- a narrow-band OFDM (orthogonal frequency divison multiplex, multi-carrier) method can be used for the supply of the data by means of a carrier frequency system.
- This method is also known under "Power Line Communication (PLC)”.
- PLC Power Line Communication
- Modems using this method are currently being used in remote power supply remote metering or distributed remote communication (DLC) networks. It succeeds over conventional power supply lines without additional cabling information exchange over several kilometers without repeaters with data rates of a few hundred kilobaud.
- the data is modulated onto the power supply in several carrier frequencies, fed with slip rings in the drill string and transmitted in the rotating drill string via the connecting elements at the pipe ends to the receiving point (consumer, electronic measuring system) in the borehole.
- the receiving point consumer, electronic measuring system
- Several such modems can not only receive energy but also data through the connected power supply.
- Advantages of this problem solution include the fact that the use of PLC modulation does not require separate cabling for data communication. This solution is therefore economical. For the desired drill string length (about 20km) no repeaters are necessary, which solves space or energy problems. Since no separate data cabling is necessary, eliminating additional galvanic contacts on the pipe connections. Since no repeaters are necessary, the necessary amount of energy is reduced so that in an economical choice of the necessary conductor cross-section (eg 4-6mm 2 ) a mains voltage (eg 400V) is sufficient to the required energy (eg 200W) to a ca. 20km to bring distant consumers.
- a mains voltage eg 400V
- the presence of a permanent power supply allows the cooling of electronic systems in the drill string and thus allows a larger drilling depth (temperature coefficient in the hole approx. 3.3 ° C / 100m) or longer residence time.
- Energy and data Supply allows a number of new applications. Limiting the supply voltage to, for example, 400V allows the choice of a standard cable (eg 240 / 400V) and reduces the required isolation distances in the mechanical design of the system components compared to high voltage systems.

- a device according to the invention which is used for connecting drill pipes 32, for example drill strings in drilling rigs.
- the device according to the invention comprises a first connecting element 1, which is referred to as a "pin” in the sequence, and a second connecting element 2, which is referred to in the sequence as "box” on.
- the pin 1 and the box 2 are connected in a manner not shown with drill pipes 32, which may be made for example of steel, CFRP or GRP.
- the inner diameter of the pin 1 and the box 2 substantially corresponds to the inner diameter of the drill pipe 32, whereas the outer diameter of the pin 1 and the box 2 is larger than the outer diameter of the drill pipe 32.
- a slip ring 3 and a catch ring 4 are rotatably received, which are surrounded by an outer ring 5 in the assembled state.
- the diameter of the outer ring 5 is slightly larger than the diameter of pin 1 and box 2 and made of a wear-resistant material, so that it can serve as a wear part, easily replaced can protect pin 1 and box 2 from excessive wear.
- the pin 1 At its end facing the box 2 6, the pin 1 has a conically tapered outer diameter with an external thread.
- the box 2, at its end 7 facing the pin 1 has a conically widening inner diameter with the same cone angle and an internal thread. The pin 1 and the box 2 can be screwed together in this way by a few rotations over a relatively long length.
- the slip ring 3 consists, as shown in Fig. 8 in detail, of an inner ring 8 which is arranged on the pin 1, and an outer ring 9, which is rotatable relative to the inner ring 8 in the circumferential direction. In the axial direction of the outer ring 9 is fixed relative to the inner ring 8.
- the slip ring 3 is - apart from the below-explained details - otherwise known as known from the prior art.
- two electrical contact elements in the form of contact pins 10 are arranged in the illustrated embodiment, which are electrically connected to brushes of the outer ring 9. It can be the same number of contact pins 10 as sliding contacts on the slip ring 3 may be present. But it is also possible to provide a particularly secure electrical connection, per sliding contacts, for example, two pins 10 provide. Alternatively, it is also possible to provide more sliding contacts than contact pins 10 by default, in order to provide the possibility of further electrical connections between the pin 1 and the box 2, if required.
- the catching ring 4 is shown in more detail. He has four through holes 11 for pins 10 in the illustrated embodiment. In addition, it has on the slip ring 3 side facing receptacles 12 (eleven receptacles 12 in the illustrated embodiment) for compression springs 13, which are supported on the end face 14 of the outer ring 9. The compression springs 13 are completely absorbed in the receptacles 12 in the compressed state. On the receptacles 12 and compression springs 13 opposite side a catch pin 15 is slidably mounted in the axial direction against a compression spring, not shown, on the catching ring 4. On the same side on which the catch pin 15 is located, the passage openings 11 are closed by a seal 16, which, however, can be penetrated by the contact pins 10 and after retraction of the contact pins 10, the passage openings 11 also closes again.
- a seal 16 which, however, can be penetrated by the contact pins 10 and after retraction of the contact pins 10, the passage openings 11 also closes again.
- a sealing ring 18, for example, an O-ring arranged on the outer circumference of the catching ring 4 on the slip ring 3 side facing on a bead 17, a sealing ring 18, for example, an O-ring arranged.
- the outer ring 5 is screwed by a thread 21 with the pin 1 and the catching ring 4 lies with its sealing ring 18 on the inside of the outer ring 5 sealingly.
- a groove 19 in the region under the catching ring 4 is arranged on the pin 1, in which a sealing ring 20, for example an O-ring, is located, which also rests sealingly against the inside of the catching ring 4.
- a catch opening 22 for the catch pin 15 and on the other hand contact elements in the form of two contact sockets 23. Since only two pins 10 are used in the embodiment shown in the drawings, only two contact sockets 23 are present. In addition to the two contact sockets 23 two more receptacles 24 are arranged, which can be equipped with contact sockets 23 if necessary. In Fig. 3 it can be seen that the contact sockets 23 and the receptacles 24 are also closed by a seal 25, which can also be penetrated by the contact pins 10 and after retraction of the contact pins 10, the contact sockets 23 close again. The seal 25 is not shown in Fig. 7.
- the seals 16 and 25 are perforable seals and may for example be made of rubber and be provided from the beginning with a perforation, which facilitates the penetration and withdrawal of the contact pins 10, although it must be ensured that the seals 16 and 25 without pins 10 are so dense that no spark or arc can be skipped or ignited when the pins 10 or contact sockets 23 are under tension to minimize any risk of explosion.
- the seal must prevent the risk of contamination and the ingress of various liquids under the harsh conditions of a drilling process.
- FIG. 9 shows a section of the box 2, in which a bore 26, which initially leads obliquely outward from the interior of the box 2, and furthermore a bore 27 which branches off in the axial direction and which leads to a recess 28, can be seen in which the contact sockets 23 are received.
- the contact sockets 23 can be connected to a arranged in the interior of the drill pipe 32 line.
- Fig. 10 is a section through the pin 1 is shown, in which a bore 29 can be seen, which leads from the interior of the pin 1 to the slip ring, not shown in this drawing.
- a line arranged in the interior of a drill pipe 32 optionally via a pin 1 in the interior of the bore 28 subsequent, not shown elbow, are also connected to the sliding contacts of the inner ring 8.
- a pin 1 will be arranged on a drill pipe 32 at one end and a box 2 on the other end, the respective contact elements (contact pins 10 and contact bushes 23) being connected to one another via the electrical line extending inside the drill pipe 32.
- the screwing together of pin 1 and box 2 takes place according to the invention as follows. In a separate state of pin 1 and box 2, the catching ring 4 is pushed away from the compression springs 13 so far from the outer ring 9, that its bead 17 and its sealing ring 18 rests against an inwardly projecting projection 30 of the outer ring 5.
- the tips of the contact pins 10 are so far in the catching ring 4 pulled inwards that they are behind the seal 16 and do not penetrate. If the box 2 is inserted over the conical end 6 of the pin 1 and thereby twisted to screw the box 2 to the pin 1, the box 2 comes with its end face 31 first in contact with the catch pin 15, against the force of its compression spring is pushed back into the catching ring 4 and at the latest after a complete rotation of the box 2 into the catching hole 22 engages.
- the construction solves the problem that during the screwing of the two connecting elements, two components of movement occur, namely one in the circumferential direction and one in the axial direction of the connecting elements. Due to the fact that one of the two contact element is movable in the circumferential direction, it may rotate in the production of electrical or galvanic connections between the two contact element with the other connecting element, so that the two connecting elements are connected to each other only via the axial movement component have to.
- the compensation of the relative movement of the pin 1 and the box 2 for the preparation of the electrical connection during the Verschraubungsrata can also be done in other ways. Essential is the resolution of the degrees of freedom of movement between the pin 1 and the box 2 in the screw in the circumferential direction and in the axial direction.
- the position of the one contact element 10, for example the plug position in pin 1, must be aligned with the position of the other contact element 23, eg the socket position in the box 2, during the screwing so that the electrical contact pins engage in the housing meet electrical sockets.
- This can preferably but not necessarily be done via spring-loaded or electrically or magnetically activated catch pins 15, which are placed on pin 1 or on the box 2 and ensure positioning of the contact pins during Verschraubreaes in the circumferential direction.
- a drill pipe 32 is shown, to which at one end a pin 1 and at the other end a box 2 are arranged.
- the drill pipe 32, the pin 1 and the box 2 are made in one piece, which is a possible embodiment.
- the drill pipe 32, the pin 1 and the box 2 but be separate components, which are firmly connected.
- a cable pipe 33 can be arranged within the drill pipe 32, which via elbows 34, 35 to the pin 1 and the box 2 or the bores 26, 29 provided therein are connected.
- elbows 34, 35 to the pin 1 and the box 2 or the bores 26, 29 provided therein are connected.
- fittings 36 are used, which seal the holes 26, 29 via conical shoulders 37 against the interior of the drill pipe 32.
- the elbows 34, 35 screwed tight.
- One or more electrical lines can be laid in this way from the pin 1 to the box 2, without coming into contact with the flushing liquid located inside the drill pipe 32.
- the electrical connection may e.g. be made by means of slip rings, wherein the electrical transmission between the outer ring and inner ring by means of balls (such as a ball bearing), or by means of two mutually abrasive metal rings (such as a plain bearing) or by means of electrical brushes can take place.
- balls such as a ball bearing
- two mutually abrasive metal rings such as a plain bearing
- a cable to compensate for the rotational movement, e.g. on a cable drum, which is provided with a spiral or coil spring, wound up. It would also be possible, for example, to use a spiral or helical spring itself as an electrical conductor which compensates for the relative movement between the movable contact element and the pin 1 or the box 2.
