Definitions

  • This invention relates to telemetry systems for use with installations in oil and gas wells or the like.
  • the invention relates to wireless telemetry systems for transmitting data and control signals between surface installations and downhole tools.
  • Downhole testing is traditionally performed in a "blind fashion": downhole tools and sensors are deployed in a well at the end of a tubing string for several days or weeks after which they are retrieved at surface. During the downhole testing operations, the sensors may record measurements that will be used for interpretation once retrieved at surface. It is only after the downhole testing tubing string is retrieved that the operators will know whether the data are sufficient and not corrupted. Similarly when operating some of the downhole testing tools from surface, such as tester valves, circulating valves, packer, samplers or perforating charges, the operators do not obtain a direct feedback from the downhole tools.
  • an acoustic telemetry system is used to pass data across an obstruction in the tubing, such as a valve. The data is then stored for retrieval by a wireline tool passed inside the tubing from the surface. It is also proposed to retransmit the signal as an acoustic signal.
  • EP1882811 discloses an acoustic transducer structure that can be used as a repeater along the tubing.
  • a first aspect of this invention provides apparatus for transmitting data in a borehole between a downhole tool installation including one or more tools (for example downhole testing tools) and a surface installation, wherein the downhole tool installation is connected to the surface installation by means of a tubular conduit (such as a drill string or production tubing), the apparatus comprising
  • the hub further comprises an acoustic transmitter which is operable to transmit the acoustic signals received by the hub to the surface installation via the tubular conduit.
  • One or more acoustic repeaters can be disposed along the tubular conduit and operated to retransmit the acoustic signal received from the hub.
  • At least one tool can be located below and/or above the hub.
  • the downhole installation typically comprises at least one packer to isolate a zone of the borehole below the hub.
  • multiple packers are arranged to isolate multiple zones of the well below the hub.
  • the downhole installation can comprise separate tools in each zone.
  • the hub can further comprise an electromagnetic receiver for receiving electromagnetic signals from the surface installation, and an acoustic transmitter for transmitting acoustic signals derived from the received electromagnetic signals.
  • a second aspect of the invention provides a method of communicating between one or more tools comprising a downhole installation and a surface installation, wherein the downhole installation and surface installation are connected by means of a tubular conduit, the method comprising:
  • the tool signals can be preferably electrical signals or digital signals.
  • the method further comprises generating acoustic signals at the hub which pass along the tubular conduit to the surface installation.
  • the method can also include receiving the acoustic signals and retransmitting them at multiple locations along the tubular conduit.
  • One preferred embodiment further comprised transmitting electromagnetic signals from the surface installation to the hub and converting these signals into acoustic signals for transmission to the tools in the installation.
  • FIG. 1 shows a schematic view of such a system.
  • the drilling apparatus is removed from the well and tests can be performed to determine the properties of the formation though which the well has been drilled.
  • the well 10 has been lined with a steel casing 12 (cased hole) in the conventional manner, although similar systems can be used in unlined (open hole) environments.
  • testing apparatus In order to test the formations, it is necessary to place testing apparatus in the well close to the regions to be tested, to be able to isolate sections or intervals of the well, and to convey fluids from the regions of interest to the surface.
  • the well-head equipment 16 can include blow-out preventers and connections for fluid, power and data communication.
  • a packer 18 is positioned on the drill pipe 14 and can be actuated to seal the borehole around the drill pipe 14 at the region of interest.
  • Various pieces of downhole test equipment 20 are connected to the drill pipe 14 above or below the packer 18. These can include:
  • a sampler 22 is located below the packer 18 and a tester valve 24 located above the packer 18.
  • the downhole equipment 20 is connected to a downhole modem 26 which is mounted in a gauge carrier 28 positioned between the sampler 22 and tester valve 24.
  • the modem 26 operates to allow electrical signals from the equipment 20 to be converted into acoustic signals for transmission to the surface, and to convert acoustic tool control signals from the surface into electrical signals for operating the equipment downhole.
  • FIG. 2 shows the modem 26 in more detail.
  • the modem comprises a housing 30 supporting a piezo electric actuator or stack 32 which can be driven to create an acoustic signal in the drill pipe 14 when the modem 26 is mounted in the gauge carrier 28.
  • the modem 26 can also include an accelerometer 34 or monitoring piezo sensor 35 for receiving acoustic signals. Where the modem is only required to act as a receiver, the piezo actuator 32 may be omitted.
  • Transmitter electronics 36 and receiver electronics 38 are also located in the housing and power is provided by means of a battery, such as a lithium rechargeable battery 40. Other types of power supply may be used also.
  • the transmitter electronics 36 are arranged to receive an electrical output signal from a sensor 42, for example from the downhole equipment 20 provided from an electrical or electro/mechanical interface.
  • signals are typically digital signals which can be provided to a micro-controller 43 which uses the signal to derive a modulation to be applied to a base band signal in one of a number of known ways FSK, PSK, QPSK, QAM.
  • This modulation is applied via a D/A converter 44 which outputs an analogue signal (typically a voltage signal) to a signal conditioner 46.
  • the conditioner operates to modify the signal to match the characteristics of the piezo actuator 32.
  • the analogue signals are stacked and applied as a drive signal to the piezo stack so as to generate an acoustic signal in the material of the drill pipe 14.
  • the acoustic signal comprises a carrier signal with an applied modulation to provide a digital signal that passes along the drill pipe as a longitudinal and/or flexural wave.
  • the acoustic signal typically has a frequency in the range 1-10kHz, preferably in the range 3-6kHz, and is configured to pass data at a rate of about 1 bps to about 1000 bps, preferably from about 10 to about 100 bps,and more preferably from over about 80 bps.
  • the data rate is dependent upon the conditions such as the noise and the distance between the repeaters.
  • a preferred embodiment of the invention is directed to a combination of a short hop acoustic telemetry system for transmitting data between a hub located above the main packer and a plurality of downhole tools and valves below and/or above said packer. Then the data and/or control signals can be transmitted from the hub to a surface module either via a plurality of repeaters as acoustic signals or by converting into electromagnetic signals and transmitting straight to the top.
  • the combination of a short hop acoustic with a plurality of repeaters and/or the use of the electromagnetic waves allows an improved data rate over existing systems.
  • the system may be designed to transmit data as high as 1000 bps. Other advantages of the present invention system exist.
  • the receiver electronics are arranged to receive the acoustic signal passing along the drill pipe 14 and convert it to an electric signal.
  • the acoustic signal passing along the pipe excites the accelerometer 34 or monitor stack 35 so as to generate an electric output signal (voltage).
  • This signal is essentially an analogue signal carrying digital information.
  • the analogue signal is applied to a filter 48 and then to a A/D converter 50 to provide a digital signal which can be applied to a microcontroller 52.
  • the micro controller 52 which implements signal processing. The type of processing applied to the signal depends on whether it is a data signal or a command signal.
  • the signal is then passed on to an actuator 54.
  • the modem 26 can therefore operate to transmit acoustic data signals from the sensors in the downhole equipment 20 along the drill pipe 14.
  • the electrical signals from the equipment 20 are applied to the transmitter electronics 36 (described above) which operate to generate the acoustic signal.
  • the modem 26 can also operate to receive acoustic signals control signals to be applied to the downhole equipment 20.
  • the acoustic signals are detected and applied to the receiver electronics 38 (described above) which operate to generate the electric control signal that is applied to the equipment 20.
  • a series of repeater modems 56a, 56b, etc. are positioned along the drill pipe 14. These repeater modems 56 operate to receive an acoustic signal generated in the drill pipe by a preceding modem and to amplify and retransmit the signal for further propagation along the drill string.
  • the number and spacing of the repeater modems 56 will depend on the particular installation selected, for example on the distance that the signal must travel. A typical minimum spacing to the modems is 500m in order to accommodate all possible testing tool configurations.
  • the acoustic signal When acting as a repeater, the acoustic signal is received and processed by the receiver electronics 38 and the output signal is provided to the microcontroller of the transmitter electronics 36 and used to drive the piezo stack in the manner described above.
  • an acoustic signal can be passed between the surface and the downhole location in a series of short hops.
  • the role of a repeater is to detect an incoming signal, to decode it, to interpret it and to subsequently rebroadcast it if required.
  • the repeater does not decode the signal but merely amplifies the signal (and the noise). In this case the repeater is acting as a simple signal booster. However, this is not the preferred implementation selected for wireless telemetry systems of the invention.
  • Repeaters are positioned along the tubing/piping string. A repeater will either listen continuously for any incoming signal or may listen from time to time.
  • the acoustic wireless signals propagate in the medium (the drill pipe) in an omni-directional fashion, that is to say up and down. It is not necessary for the detector to detect whether the physical wireless signal is coming from another repeater above or below.
  • the direction of the message is embedded in the message itself.
  • Each message contains several network addresses: the address of the transmitter (last and/or first transmitter) and the address of the destination modem at least. Based on the addresses embedded in the messages, the repeater will interpret the message and construct a new message with updated information regarding the transmitter and destination addresses. Messages will be transmitted from repeaters to repeaters and slightly modified to include new network addresses.
  • the repeater includes an array of sensors, and if the channel is non reverberant, then it is possible to determine the direction of the incoming signal, using classical array processing (similar to that found in borehole seismics, acoustic tools, phased array radars or ultrasonic, etc). This applies for a propagating wave (acoustic or high frequency electromagnetic, for example), but not for a diffusive wave such as a low frequency electromagnetic wave.
  • a surface modem 58 is provided at the well head 16 which provides a connection between the drill pipe 14 and a data cable or wireless connection 60 to a control system 62 that can receive data from the downhole equipment 20 and provide control signals for its operation.
  • the acoustic telemetry system is used to provide communication between the surface and the downhole location.
  • Figure 3 shows another embodiment in which acoustic telemetry is used for communication between tools in multi-zone testing.
  • two zones A, B of the well are isolated by means of packers 18a, 18b.
  • Test equipment 20a, 20b is located in each isolated zone A, B, corresponding modems 26a, 26b being provided in each case. Operation of the modems 26a, 26b allows the equipment in each zone to communicate with each other as well as allowing communication from the surface with control and data signals in the manner described above.
  • Figure 4 shows an embodiment of the invention with a hybrid telemetry system.
  • the testing installation shown in Figure 4 comprises a lower section 64 which corresponds to that described above in relation to Figures 1 and 3 .
  • downhole equipment 66 and packer(s) 68 are provided with acoustic modems 70.
  • the uppermost modem 72 differs in that signals are converted between acoustic and electromagnetic formats.
  • Figure 5 shows a schematic of the modem 72.
  • Acoustic transmitter and receiver electronics 74, 76 correspond essentially to those described above in relation to Figure 2 , receiving and emitting acoustic signals via piezo stacks (or accelerometers).
  • Electromagnetic (EM) receiver and transmitter electronics 78, 80 are also provided, each having an associated microcontroller 82, 84.
  • a typical EM signal will be a digital signal at about 1 Hz.
  • This signal is received by the receiver electronics 78 and passed to an associated microcontroller 82.
  • Data from the microcontroller 82 can be passed to the acoustic receiver microcontroller 86 and on to the acoustic transmitter microcontroller 88 where it is used to drive the acoustic transmitter signal in the manner described above.
  • the acoustic signal received at the receiver microcontroller 86 can also be passed to the EM receiver microcontroller 82 and then on to the EM transmitter microcontroller 84 where it is used to drive an EM transmitter antenna to create a 1 Hz digital EM signal that can be transmitted along the well to the surface.
  • a corresponding EM transceiver (not shown) is provided at the surface for connection to the control system.
  • Figure 6 shows a more detailed view of a downhole installation in which the modem 72 forms part of a downhole hub 90 that can be used to provide short hop acoustic telemetry X with the various downhole tools 20 (e.g test and circulation valves (i), flowmeter (ii), fluid analyser (iii) and packer (iv), and other tools below the packer (v)), and long hop EM telemetry Y to the surface.

  • long hop EM telemetry Y e.g test and circulation valves (i), flowmeter (ii), fluid analyser (iii) and packer (iv), and other tools below the packer (v)
  • FIG. 7 shows the manner in which a modem can be mounted in downhole equipment.
  • the modem 92 is located in a common housing 94 with a pressure gauge 96, although other housings and equipment can be used.
  • the housing 94 is positioned in a recess 97 on the outside of a section of drill pipe 98 provided for such equipment and commonly known as a gauge carrier.
  • the gauge carrier 97 By securely locating the housing 94 in the gauge carrier 97, the acoustic signal can be coupled to the drill pipe 98.
  • each piece of downhole equipment will have its own modem for providing the short hop acoustic signals, either for transmission via the hub and long hop EM telemetry, or by long hop acoustic telemetry using repeater modems.
  • the modem is hard wired into the sensors and actuators of the equipment so as to be able to receive data and provide control signals.
  • the modem will be used to provide signals to set/unset, open/close or fire as appropriate.
  • Sampling tools can be instructed to activate, pump out, etc. and sensors such as pressure and flow meters can transmit recorded data to the surface. In most cases, data will be recorded in tool memory and then transmitted to the surface in batches.
  • tool settings can be stored in the tool memory and activated using the acoustic telemetry signal.
  • Figure 8 shows one embodiment for mounting the repeater modem on drill pipe.
  • the modem 100 is provided in an elongate housing 102 which is secured to the outside of the drill pipe 104 by means of clamps 106.
  • Each modem is a stand-alone installation, the drill pipe providing both the physical support and signal path.
  • Figure 9 shows an alternative embodiment for mounting the repeater modem.
  • the modem 108 is mounted in an external recess 110 of a dedicated tubular sub 112 that can be installed in the drill string between adjacent sections of drill pipe. Multiple modems can be mounted on the sub for redundancy.
  • the preferred embodiment of the invention comprises a two-way wireless communication system between downhole and surface, combining different modes of electromagnetic and acoustic wave propagations. It may also include a wired communication locally, for example in the case of offshore operations.
  • the system takes advantage of the different technologies and combines them into a hybrid system, as presented in Figure 4 .
  • the purpose of combining the different types of telemetry is to take advantage of the best features of the different types of telemetry without having the limitations of any of them.
  • the preferred applications for embodiments of this invention are for single zone and multi-zone well testing in land and offshore environments.
  • the communication link has to be established between the floating platform (not shown) and the downhole equipment 66 above and below the packer 68.
  • the distance between the rig floor (on the platform) and the downhole tools can be considerable, with up to 3km of sea water and 6km of formation/well depth.

  • the main drawbacks of the electromagnetic wave communication are related to the required power and associated footprint.
  • Acoustic wave propagation 126 along the tubing string 124 can be made in such a way that each element of the system is small and power effective by using high frequency sonic wave (1 to 10kHz).
  • the main advantages of this type of acoustic wave communication relate to the small footprint and the medium date rate of the wireless communication.
  • the main drawbacks of the acoustic wave communication are related to the impact of noise induced by production flows, the unpredictability of the communication carrier frequency and the requirements for continuity in the pipe structure.
  • Electrical or optical cable technology 128 can provide the largest bandwidth and the most predictable communication channel.
