Definitions

  • the invention relates to a device for transmitting information and / or control signals in a drill string during the operation of a drill comprising a drill bit, in particular for transmitting information and / or control signals from the borehole to the surface of the earth, in an embodiment according to the preamble of claim 1.
  • the devices for information data acquisition and the processor for converting the data into a sequence of electrical control signals are combined in the same housing insert or in separate, immediately adjacent housing inserts, which are galvanically connected, for example, by plug connections can be coupled together.
  • Such an arrangement is, however, only suitable for devices for recording such data which do not occur or are not very selectively localized, as is the case, for example, for inclination, azimuth, temperature or pressure.
  • Devices are also known from DE-B-34 28 931 in which the information and control data signals ascertained are transmitted as pressure pulses from a transmitter to the receiver unit via the flushing liquid of the drilling device and from there to the processor.
  • This type of transmission is convincing for many areas of application, but can only be used with increased effort for certain data transmission requirements, for example for the transmission of data from a fixed drill string part to a rotating drill string part.
  • This also applies to data transmission in larger depths e.g. directional drilling.
  • the possibility of arranging pressure pulse sensors within the drill string is also limited due to the susceptibility to wear of such devices.
  • a device for the transmission of information signals in a drill string of the type mentioned is known.
  • information signals are transmitted acoustically via sound sensor / sound receiver units, but not from a fixed and a rotating drill string area.
  • the same also applies to the devices known from WO 88/01096, US-A-3,090,031 and from DE-A-39 16 704.
  • the device of the type mentioned is characterized by the features specified in the characterizing part of claim 1. Essential beneficial Refinements of the device result from claims 2 to 17.
  • the prerequisite for an increased level is initially Transmission speed with reduction of transmission errors also with eg Directional drilling given.
  • inductive data transmission and / or sound signal transmission are known components which only have to be adjusted to the operationally optimized transmission conditions depending on the application or are to be interpreted.
  • induction loops or coil formers are suitable as magnetic inductive couplers both as transmitter and receiver units, the number or diameter of windings of which can be suitably adapted to the operating conditions.
  • Magnetic field-sensitive semiconductor sensors are also suitable as inductive magnetic receiver units.
  • the magnetically inductive couplers serving as transmitters and on the one hand serving as receivers are expediently freely aligned in the end regions facing one another, as a result of which they can be coupled in a structurally simple manner by means of transformers.
  • magnetically inductive couplers are present at both ends of a pipe as receivers on the one hand and transmitters for a subsequent drill pipe on the other, these can be galvanically connected to one another by means of cable connections to be provided, but also via electrically conductive drill pipe wall parts.
  • Electrically conductive drilling tube wall parts can be adapted to the outside or inwards of the transmission tasks of coil bodies in such a way that they have a sufficient gap to the coil body so as not to adversely influence the alternating magnetic fields due to their electrical conductivity.
  • the information and / or control signals received by the receiver unit of the transmission link are sent to a transmitter unit of a further transmission link, from where they are passed on.
  • both the magnetic-inductive couplers and the sound sensors or receivers of the transmission link can be coupled to this further transmission link, which has transmission elements known from DE-B-34 28 931 as transmitter and receiver units, such as pressure pulse transmitters.
  • the pressure pulses are transmitted to the pressure pulse receiver unit via the flushing liquid of the drilling device forming the further transmission path is known to the processor for processing the received information or control signals.
  • the drilling devices with devices according to the invention illustrated in the drawing each comprise a drill string, designated as a whole as 1, with an inner channel 2 and an annular space 3 surrounding the drill pipe string 1.
  • the drill string 1 is used for directional drilling.
  • the drill string 1 in turn has an inner channel 2 and an annular space 3 surrounding the drill string 1.
  • flushing liquid is pumped down through the inner channel 2 by means of a pump, not shown, which drives a drilling turbine, not shown, on its way to the bottom of the borehole and exits into the borehole through nozzles of the rotary drill bit 5 driven by the drilling turbine and returns to the earth's surface through the annular space 3 surrounding the drill pipe string.
  • a sensor 7 for inclination and direction measurement data is arranged above the rotary drill bit 5 and is connected to the structure-borne sound transmitter 11.
  • a joint piece 13 is present between the structure-borne sound transmitter 11 carrying drill pipe and the underground drilling motor 12 with flushing drive. Another joint piece 13 is provided between the motor 12 and the drill pipe carrying the structure-borne sound receiver 14.
  • the inclination and direction measurement data determined by the sensor 7 are transmitted from the transmitter 11 to the receiver 14 by structure-borne noise.
  • a pressure pulse transmitter 15 of a known type is arranged above the receiver 14 and forwards the signals received by the receiver 14 to the pressure pulse receiver 16 via a further transmission path which is formed by the flushing liquid in the inner tube 2. These are evaluated in processor 10 after conversion into electrical signals.
  • a first sensor 17 for determining contact pressure signals is arranged above the rotary drill bit 5 of the drill string 1. This is galvanically connected to a coil former 18.
  • the coil former 18 is a transmitter for magnetically inductive transmission of the received signals to a coil former 20 coupled to the coil 18 via the free air gap 19, which coil therefore represents the receiver of this magnetically inductive transmission path, so that the data transmission from the rotating parts 5, 17 is contactless and the outer tube 21 of the drill string 1 carrying the bobbin 18 onto the non-rotating drill pipe wall parts 22 and the drill motor 23 connected thereto.
  • the signals from the sensor 17 are transmitted via the underground motor 23 by means of galvanic coupling a cable connection 24 is forwarded to an inclination and direction sensor 25.
  • the measurement data generated in the two sensor units 17 and 25 are then passed on together from the pressure pulse transmitter unit via the flushing liquid column in channel 2 of the drill pipe in a known manner to the pressure pulse receiver 16 and from there via a cable connection to the processor after conversion into electrical signals.
  • an inclination and direction sensor is connected both to a pressure pulse transmitter 27 for transmitting the inclination and direction measurement signals to the pressure pulse receiver 28 and forwarded to the processor 10 after conversion into electrical signals, and also to a structure-borne sound transmitter via a cable connection 29 30 for short-range data transmission to a structure-borne sound receiver 31.
  • a pressure pulse transmitter 27 for transmitting the inclination and direction measurement signals to the pressure pulse receiver 28 and forwarded to the processor 10 after conversion into electrical signals
  • a structure-borne sound transmitter via a cable connection 29 30 for short-range data transmission to a structure-borne sound receiver 31.
  • antimagnetic collars 32 so as not to influence the inclination and direction data determination with the aid of magnetically sensitive sensors.
  • control signals transmitted from the inclination and direction sensor 26 via structure-borne sound to the structure-borne sound receiver 31 are given to the directional drilling tool 34 via a cable connection 33, so that control movements as long as deviations occur between a predetermined direction or inclination and the actual values detected by the sensor 26 are to be carried out until the deviation has decreased within a specifiable tolerance range.
  • transmission devices and sensors in general may require further electronic components for signal processing as well as batteries or generators driven by the drilling fluid or revolving drill string parts for generating electrical energy, which, however, are known per se and are provided in a suitable manner can.
