Definitions

  • the present invention relates to a downhole tool system for being submerged into a casing, comprising at least three tools. Furthermore, the invention relates to a communication method for communicating wirelessly between a first and a third tool separated by a second tool.
  • well fluid is most often very inhomogeneous as it comprises mud, scales, both oil and water, and gas bubbles. Therefore, the communication sometimes fails.
  • a downhole tool system for being submerged into a casing comprising at least three tools:
  • the acoustic devices arranged at each end of the intermediate tool are able to send acoustic signals propagating along the housing of the intermediate and second tool.
  • the housing is often made of a solid material, increasing its transmitting ability compared to the transmitting ability in the surrounding well fluid which may be inhomogeneous and thereby be a poor transmitting media compared to a metal housing.
  • the three tools are most often connected by means of threaded connections providing a sufficiently firm connection for transmitting acoustic signals from the first or third tool to the second tool.
  • the first and second acoustic devices may comprise means for converting data parameters into electric signals and transducers for receiving the electrical signal and generating acoustic signals propagating along the housing of the second tool.
  • the transducers may abut the ends of the second tool.
  • the transducers of the first and second acoustic devices may face the second tool, causing the acoustic signals to propagate axially along the housing of the second tool.
  • the first and second communication devices may be antennas instead of acoustic devices, sending and receiving radio waves.
  • the antennas may transmit signals having a wavelength of 1-2 cm.
  • the third tool may be a logging tool.
  • the first tool may comprise an electronic motor.
  • first and/or second communication device(s) may comprise a memory.
  • the first and/or second communication device(s) may comprise a processing unit for processing data before converting the data into acoustic signals.
  • the transducer may be a magnetostrictive transducer.
  • the acoustic devices may comprise piezoelectric microphones.
  • the first tool may be connected with a wireline.
  • the first or third tool may comprise a driving unit, such as a downhole tractor.
  • the communication device may comprise a battery.
  • the acoustic devices may comprise mechanical or electronic filters.
  • the present invention furthermore relates to a communication method for communicating wirelessly between a first and a third tool separated by a second tool, comprising the steps of:
  • the communication method may further comprise the step of converting data parameters into electric signals.
  • Fig. 1 shows a downhole tool system 1 comprising three tools; a first 1, a second 2 and a third 3 tool, arranged as a tool string.
  • the first tool 1 is connected to a wireline at its first end 11 to power the tool string.
  • the first tool 1 is connected to a first end 21 of the second tool 2 by means of a threaded connection firmly connecting the first 1 and second 2 tools.
  • the second tool 2 is connected to a first end 31 of the third tool 3, also by means of a threaded connection.
  • Two operators may work together to perform a well operation in the sense that a tool of one operator is arranged between the tools of another operator.
  • the first 1 and the third tool 3 come from a first operator and the second tool 2 comes from a second operator. Since the first 1 and third 3 tools are separated by the second tool 2, communication between the tools of the first operator cannot take place inside the tools in the conventional way since it is not possible to communicate through the second tool 2. This is due to the fact that the second operator uses a different communication system than the first operator and that it is not possible to pull wires through the intermediate tool without having to substantially reconstruct this tool.
  • the first 1 and third 3 tools comprise communication devices 13, 33 in the form of acoustic devices.
  • the acoustic device of the first tool 1 is arranged in a housing wall at the second end 12 of the first tool 1, abutting the first end 21 of the second tool 2, thereby being able to generate acoustic signals propagating axially along the housing 23 of the second tool 2.
  • the acoustic device of the third tool 3 is arranged in a housing wall at the first end 31 of the third tool 3, abutting the second end 22 of the second tool 2, thereby also being able to generate acoustic signals propagating axially along the housing 23 of the second tool 2.
  • Each acoustic device comprises a transducer 5 facing the end of the housing 23 of the second tool 2.
  • the transducers 5 may be magnetostrictive transducers transmitting acoustic signals in the form of longitudinal sonic waves along the housing 23 of the second tool 2.
  • the communication devices 13, 33 comprise antennas for sending and receiving radio waves having wavelengths of 1-2 cm.
  • the antennas are arranged so that they project only partly from the outer faces of the first 1 and third tools 3 and extend parallel to the longitudinal extension of the tools.
  • the radio waves propagate in the well fluid along the tool string without being substantially destroyed when hitting the wall of the tools 1, 2, 3 or the wall of the production casing 10.
  • the antennas are arranged in the housings of the first 1 and third 3 tools and are isolated from the other parts of the tools to improve the quality of the communication between the first 1 and third 3 tools.
  • the antennas may also be projecting parts of the tools and be projected as required and maintained inside the tools when the tool string is submerged into the casing 10.
  • fluid or well fluid any kind of fluid that may be present in oil or gas wells downhole, such as natural gas, oil, oil mud, crude oil, water, etc.
  • gas is meant any kind of gas composition present in a well, completion, or open hole
  • oil is meant any kind of oil composition, such as crude oil, an oil-containing fluid, etc.
  • Gas, oil, and water fluids may thus all comprise other elements or substances than gas, oil, and/or water, respectively.
  • a casing any kind of pipe, tubing, tubular, liner, string etc. used downhole in relation to oil or natural gas production.
  • a downhole tractor can be used to push the tools all the way into position in the well.
  • a downhole tractor is any kind of driving tool capable of pushing or pulling tools in a well downhole, such as a Well Tractor®.
