Generally, the operating oscillating circuits can be located in or integrated with any downhole system or in the annular space.
  • a fundamentally new system is provided for signal and power transmission to the bottomhole well region and for data transmission from the bottomhole well region to the surface.
  • the method provided herein is based on wireless data transmission using electromagnetic interconnection to provide signal propagation. This technology allows signals or power to be transmitted at a high speed and with an acceptable level of losses or distortions.
  • the system can be operated at different well depths, in different mud media, in combination with different drilling technologies etc. The result is achieved due to the installation of additional properly spaced downhole devices to provide communication along the entire well depth.
  • the fundamental principle of the electromagnetic signal transmission method suggested herein is based on the use of a set of resonance oscillating circuits installed along the entire well depth and interconnected, for example, by mutual induction.

  • Data can be transmitted by modulating the oscillations.
  • the applied signal is modulated. If data are transmitted from the surface to the bottomhole region, the applied signal is modulated. If data are to be transmitted from the bottomhole region to the surface, the oscillations of the entire set of interconnected oscillating circuits can be modulated by the oscillating circuit located in the bottomhole region and connected, for example, with a metering device. This process can be considered as a reflection of the applied signal combined with certain data bearing modulation. This means that changing the parameters of one of the oscillating circuits changes the parameters of its oscillations. This change in turn affects the other interconnected oscillating circuits to transmit the excitation via the chain of the oscillating circuits to the top oscillating circuit located, as noted above, at the well head. This excitation can be decoded at the surface as a bit of data by measuring the oscillations of the first oscillating circuit.

  • the oscillating circuits are mounted on the string with spaces sufficient for signal transmission.
  • the interconnection of the oscillating circuits is provided by mutual induction, for example, when induction frames are properly spaced.
  • the first oscillating circuit is installed at the well head and differs from the other oscillating circuits by the availability of a source of alternating voltage U 0 (or current) connected, for example, in parallel as shown in Fig. 2.
  • the design of the metering oscillating circuit is shown in Fig. 3.
  • the data transmission algorithm is as follows. When the main oscillating circuit power source is on, oscillations of the electric current I are generated in the oscillating circuit with the frequency co 0 :
  • R is determined by the effective resistance of the conductors in each oscillating circuit
  • C is the capacity included in each oscillating circuit
  • N is the number of oscillating circuits installed in the well.
  • the first oscillating circuit can be installed directly at the well head.
  • the conductor coils of that first oscillating circuit will have a greater diameter than those of the other oscillating circuits and hence the inductivity of the oscillating circuit will be different.
  • the resonance frequency of the first oscillating circuit co 0 can be adjusted to be at the initially required level by reducing the capacitance of the capacitor.
  • the metering oscillating circuit is differs by the possibility of modulating and/or reflecting the signal depending on the reading of the metering device installed in the downhole region.
  • the control signal is transmitted by the metering device, for example, by induction. Due to the small distance between the oscillating circuit and the metering device, high transmittance power of the metering device is not required.
  • the adjusting unit When receiving a control signal, the adjusting unit changes the parameters of the metering oscillating circuit which in turn change its response. As the oscillating circuits are inductively interconnected, this frequency excitation is transmitted via the chain of oscillating circuits to the top of the well and can be measured in the first oscillating circuit to detect this excitation as a bit of data.
  • this excitation is transmitted at the speed of electromagnetic wave, i.e. almost instantaneously, and the oscillation frequency excitation can be detected in a very short time that is only limited to the order of oscillation period which can be sufficiently short if oscillating circuit parameters are properly selected.
  • Another wide application is the distributed monitoring of pressure, temperature and other properties in horizontal wells.
  • An intelligent well is a set of works and equipment for increasing and optimizing well production.
  • This complex may comprise interval control valves, real time bottomhole control and monitoring systems and surface control system communication means.
  • this is a well equipped with monitoring systems and production equipment components for well production optimization either automatically or with the operator's interference.
  • Oil and gas well and field operation practice will undergo an unparalleled breakthrough when the industry is capable of providing a set of downhole flowrate sensors equipped with controlled valves and suitable for wireless control from the surface in order to optimize well production parameters.
  • the most critical part of this complex is the possibility of wireless communication and control of downhole tools under the conditions of strong downhole interference and losses.
