Definitions

  • the present invention relates to a method and apparatus for remotely actuating a downhole device such as a packer. Specifically, the method involves the use of a remote seismic signal that is received and decoded by a receiver on the downhole tool.
  • a bit may be suspended along with related equipment from a drill string.
  • the drill string is suspended from the crown block of a derrick by cables that bear a portion of the drill strings weight.
  • the drill string and bit are rotated by a rotary table, driving the bit into the ground.
  • a drilling mud can be circulated through the drill string to clean and cool the bit.
  • the circulating mud also carries debris from the hole by way of the annulus between the drill string and the walls of the well.
  • additional sections of drill string are added.
  • devices can be added to the drill string to help steer the bit or to perform early testing of the formation.
  • a well does not encounter commercial amounts of gas and oil, the well can be plugged and abandoned. However, if significant amounts of gas or oil are found, the well is completed.
  • casing can be cemented against the inside of the well to stabilize the wall of the well.
  • a completion string can then be lowered into the cased well.
  • the completion string can include packers to isolate specific portions of the well, perforation guns used to provide communication ports between the casing and surrounding formation, and other devices.
  • the downhole tools are actuated during the completion process. Other times, it is desirable to wait until the reservoir conditions merit the use of the specific tools. Therefore, a need exists for a method and apparatus to remotely actuate downhole tools during drilling, during completion, and after completion. It is important that such a method be non-interventional; in other words, nothing should have to be run into the well to actuate the downhole device.
  • U.S. Patent No. 5,579,283 to Owens et al. and entitled "Method and Apparatus for Communicating Coded Messages in a Wellbore” discloses a method of impressing a command message upon a fluid column between a transmission node and a reception node.
  • a transmission apparatus is in communication with the fluid column, for altering pressure of the fluid column to generate a portion of the coded message.
  • a reception apparatus is provided at the reception node.
  • the reception apparatus includes a rigid structural component with an exterior surface which is in direct contact with the fluid column, an interior surface which is not in direct contact with the fluid column, and a sensor assembly which detects elastic deformation of the rigid structural component.
  • Owens requires that the well bore be full of fluid of relatively consistent density, as the presence of a liquid/gas mixture in the well bore may attenuate the signal.
  • Owens also requires large, cumbersome surface equipment to circulate the fluid and to generate the signal.
  • Owens relies on a string gauge attached to a thin-walled section of tubing to receive the appropriate signal.
  • the present invention provides a method and apparatus for remotely transmitting an actuation signal to a downhole tool.
  • the downhole tool can be any tool that might be used during drilling or completion or after completion.
  • the tool could be a steering motor, a packer, a sliding side door, a perforation gun, a plug or other flow control device.
  • at least one or a coded sequence of seismic pulses is transmitted from a sleeve gun or other suitable transmitter.
  • the term "seismic" can mean any signal that is based on a pressure source.
  • the seismic signal can be of any suitable intensity, pulse duration or waveform.
  • the method can be used for shore completions or subsea completions.
  • the transmitter is preferably lowered into the ocean before firing.
  • the signal could be fired above water in suitable conditions.
  • the signal be initiated underground, i.e. in another nearby well.
  • the acoustic telemetry signal passes first through the ocean and then through the earth below until it reaches a hydrophone or other suitable receiver mounted near to the device to be activated.
  • the hydrophone is part of a telemetry receiver that can be battery powered.
  • the seismic telemetry signal can be a coded sequence of pulses. By changing the coding and timing sequences, a large number of separately located devices can be addressed and actuated. These devices can be in the same or different wells.
  • the down hole tool includes the telemetry receiver as well as an actuation means and a power supply.
  • the receiver can be either a hydrophone, a geophone, an accelerometer, or a pressure transducer. If the downhole tool is a packer, the actuation can be accomplished with a plug and port system wherein the signal will close a plug in the drill string and open a port to the packer. Drill string pressure can then be increased to set the packer. Once set, the port can be closed and the plug reopened.
  • the actuation means can be a hydraulic pump or a motor with a linear actuator.
  • the present system does not require a well full of fluid to operate. It does not need the large and cumbersome surface equipment required to circulate the well fluid. Further, the present system does not require large and cumbersome surface equipment to generate the signal.
  • the system does not rely on a strain gage attached to the outer diameter of the drilling/completion string to receive the signal.
  • the receiver can be coupled to the fluid inside or outside of the drilling/completion string to enhance the signal reception.
  • the present system can use a hydrophone, a geophone, an accelerometer, or pressure transducer to enhance the probability of receiving the signal. Further, the method allows more control of the coding, i.e. time, amplitude, frequency, and spectrum parameters.

  • Figure 2 is a flow chart showing the general method of actuating a downhole device using a remote seismic source.
  • a system 10 embodying the present invention is best illustrated in Figure 1.

  • the device 22 will be viewed as a packer.
  • packers 22 are well known in the art. In certain formations, several packers are used to isolate various production layers. The ability to remotely actuate certain packers and not others would greatly improve the ability to control the production of valuable hydrocarbons from the formation.
  • At least one receiver/actuator 24 is coupled to the downhole tool 22.
  • the receiver/actuator 24 can be a hydrophone, accelerometer, or preferably a geophone which is matched to a transmitter 34.

  • the receiver/actuator 24 is preferably placed against the casing to improve its ability to receive the transmitted signal 36.
  • an array of receivers might be used, each coupled to a single actuator.
  • a PC or workstation 26 can be used to initiate and code the signal burst.

  • a modulated signal could also be used.
  • the method 100 of using the remote seismic signals is disclosed in the flow chart of Figure 2. First, the unactuated device(s) must be placed 102 downhole. Next, a first coded signal must be initiated 104 and transmitted by the transmitter 34 (shown in Figure 1). This allows the actuation 106 of a first device. The process can be repeated by initiating a second signal 108 to actuate 110 a second device.

Abstract

Cette invention concerne un procédé d'actionnement à distance d'un dispositif de fond de puits (22) qui consiste à émettre un signal sismique (36) hors du puits. Un récepteur/actionneur (24) couplé au dispositif de fond de puits (22) reçoit le signal sismique (36) et actionne l'outil en réponse à ce signal. Le signal sismique (36) peut être produit à l'aide d'un canon à chemise (30). Le récepteur (24) peut consister en un géophone ou en un hydrophone. Le signal sismique (36) peut être codé de manière à actionner un dispositif spécifique, ou à actionner séquentiellement plusieurs dispositifs dans un même puits ou dans des puits différents. Le signal sismique (36) peut également être émis dans l'océan (4) afin d'actionner un dispositif de fond de puits (22) lors d'une complétion sous-marine. Dans un autre mode de réalisation, le signal sismique (36) peut également être utilisé afin d'actionner des dispositifs de fond de puits dans des complétions côtières.
