Definitions

  • the present invention pertains to oil field operations and more particularly to an apparatus and methods for activating a downhole tool.
  • a number of operations may be performed in a common oil wellbore by running tools in on a line that is controlled from the surface.
  • hardware for logging, perforating, and flow control may be run into the hole on slickline.
  • Slickline commonly comprises a thin, nonelectric cable used for selective placement and retrieval of wellbore hardware.
  • Downhole valves and sleeves can also be adjusted using slickline tools. In many such tools, such as battery powered logging tools, it is desirable to control the turn-on and operation of the tools from the surface.
  • Such tools may contain, for example, caliper arms that contact the borehole wall to enable the logging tool sensor contact with the formation surrounding the wellbore. These arms are typically in a collapsed state during transit to prevent the tool from hanging up on the way into the wellbore. In other instances, such as with perforating guns, it is desirable to prevent their arming and possible firing until they are safely downhole.
  • prior art tools have used several techniques for actuating such tools downhole. These include raising the bottomhole pressure by a predetermined amount such that a pressure sensor in the downhole tool senses the increased pressure as a signal to actuate.
  • the pressure increase may be in the form of a static increase or in the form of a sequence of pressure pulses that are detected downhole.
  • the bottomhole pressure in a well is commonly balanced to hold back formation fluid ingress to the wellbore while not exceeding the fracture pressure of the formation surrounding the wellbore.
  • the increased pressure signal in many instances, may be sufficient to cause fractures in the formation. Even if the formation does not fracture, the increased pressure in the wellbore may be sufficient to force wellbore fluids to invade the formation and cause errors in subsequent logging operations.
  • a preset time interval is set in a timer in the tool at the surface such that the tool is then deployed to the desired location before the preset time interval has been exceeded.
  • the tool is activated. Problems in deploying the tool may occur that cause the preset time interval to be exceeded before the tool is properly deployed. Activation of the tool may cause the tool to be stuck in the hole or cause damage to the wellbore.
  • an apparatus for performing a downhole operation in a wellbore comprises a tool string deployed on a slickline into the wellbore, where the tool string comprises a controller and a tool.
  • a first sensor which may be a motion detector, is disposed in the controller and senses motion of the tool string and generates a first signal in response thereto.
  • a device disposed in the tool detects a downhole parameter of interest and generates a second signal in response thereto.
  • a processor in the controller acts according to programmed instructions to activate the tool when the first signal is below a first preset threshold for at least a preset time interval and the second signal exceeds a second preset threshold.
  • a method of activating a downhole tool in a wellbore comprises deploying a tool string on a string, which may be a slickline into the wellbore.
  • the tool string is held substantially motionless for at least a preset time interval at a location in the wellbore.
  • a motion detector determines that the tool string is substantially motionless for at least the preset time interval. It is determined that a downhole detected parameter of interest exceeds a second preset threshold.
  • the tool is activated in the tool string when both the tool is substantially motionless for at least a preset time interval and the downhole detected parameter of interest exceeds a second preset threshold.
  • Figure 1 is a schematic diagram of a tool string deployed on a slickline according to one embodiment of the invention
  • Figure 2 is a block diagram showing certain operational components of the tool string according to one embodiment of the invention.

  • an exemplary downhole tool string 11 comprising downhole controller 10 and tool 18.
  • Tool string 11 is supported by a string 12 or line, which maybe a slickline.
  • Slickline 12 extends from rig 14 at the surface 16.
  • Slickline 12 is deployed from winch 29 around one or more sheave wheels 26, supported from the rig 14, and down into the borehole 20.
  • Surface controller 28 provides suitable power and controls associated with winch 29 for controlling the deployment of the slickline 12 into borehole 20.
  • winch 29 may be separately controlled and surface controller 28 may be a portable computer, such as a personal computer, having appropriate interfaces circuitry to communicate, from the surface, with downhole controller 10.
  • Tool string 11 is shown deployed adjacent a production zone 22 located, for example, near the bottom 24 of the borehole 20, also called a wellbore.
  • Borehole 20 commonly has a fluid 13 disposed therein which may be a drilling fluid (also called drilling mud), a production control fluid, and/or a produced fluid from production zone 22.
  • the produced fluid may be water, hydrocarbon liquid, gas, or any combination of the above.
  • Tool 18 may include multiple downhole tools including but not limited to: a logging tool, a perforating gun, a packer, a flow control valve, and/or any other device suitable for running on slickline 12 and performing downhole operations.
  • the logging tool includes, but is not limited to: an acoustic tool, a density tool, a neutron tool, an induction resistivity tool, an NMR tool, and a gamma ray tool.
  • the logging tool may be a single tool or any combination of such tools, as described above.
  • the downhole tools may be exposed to fluid pressures up to 30,000 psi and temperatures up to 500 0 F.
  • the downhole fluid may be brine, water-based drilling fluid, oil-based drilling fluid and/or fluids that may contain hydrogen sulfide, carbon dioxide, methane, and other deleterious compounds.
  • FIG. 2 is a block diagram showing certain operational components of the downhole controller 10 according to one embodiment of the present invention.
  • Downhole controller 10 includes processor 31 having sufficient memory therein for storing programmed instructions for operating downhole controller 10 and for storing preset sensor thresholds for use in the present invention.
  • Circuits 32 interface processor 31 with clock 35, motion sensor 33, pressure sensor 34, and temperature sensor 39 and tool 18.
  • Clock 35 may be a crystal oscillator and is used to measure elapsed time from a start signal initiated by surface controller 28 before tool string 11 is deployed in the wellbore 20. Clock 35 may be adapted to provide realtime.
  • Motion sensor 33, pressure sensor 34, and temperature sensor 39 may also be disposed in the controller 10. Motion sensor 33 is used to determine when the tool 18 and/or the string 11 is motionless or substantially motionless.
  • Clock 35 also may contain a timer for determining the length of time that the tool is held substantially motionless.
  • accelerometers 60 are mounted in the controller 10 and used to detect motion of the tool string 11. Lack of motion is determined when a signal from the accelerometers is below a selected or preset threshold level. It should be noted that the threshold level is somewhat application dependent and is field settable. For example, in a well with fluid flowing past the tool, there will be flow turbulence affecting the accelerometer signal level even when the slickline 12 is being held steady at the surface. In a non-flowing well, the accelerometer threshold may be set at a lower level.
  • noise sensor 61 may detect the noise associated with the contact of the tool string 11 with the wall of wellbore 20 and the flow noise associated with the movement of tool string 11 through either a static or flowing fluid in wellbore 20.
  • Noise sensor 61 may include a piezoelectric crystal and/or a piezoelectric film mounted on controller 10 such that noise sensor 61 is exposed to fluid 13 in wellbore 20.
  • Power source 36 provides power to operate controller 10 and its associated devices.
  • power source 36 includes batteries (not separately shown) suitable for downhole use. Such batteries are commercially available and are not described here further.
  • Controller 10 is electrically and mechanically coupled to tool 18 using techniques known in the art. Power source 36 contains sufficient power to operate tool 18. Alternatively, tool 18 contains its own separate power source.
  • Pressure sensor 34 and temperature sensor 39 may be mounted in the controller 10 such that they are able to measure the steady-state downhole pressure and temperature of fluid 13 in wellbore 20. Such sensors are commercially available and will not be described here.
  • Processor 31 contains programmed instructions for determining when to activate tool 18.
  • FIG. 3 shows an operational flow chart of an exemplary operation of the present invention.
  • a motion sensor threshold and a length of time that the tool should be motionless are programmed into processor 31 at the surface and prior to deployment into wellbore
  • At least one additional parameter threshold is also downloaded by the operator into processor 31, prior to deployment, using a connection to surface processor 28.
  • Tool string 11 is deployed into wellbore 20 in step 45.
  • Motion detection is continuous during the entire downhole operation.
  • the tool is stopped and held substantially motionless in step 46.
  • step 47 the motion detection sensor signal falls below the preset threshold level, and clock 35 begins a separate timer to determine the length of time that the tool is motionless and compare the measured time interval to the preset motionless threshold interval.
  • controller 10 proceeds to sense the additional parameter of interest and compare the measurement to its preset threshold value in step 48.
  • the additional parameter may be downhole pressure, downhole temperature, a logging tool response, a formation characteristic and/or a total deployment time interval. In the present invention, at least one additional parameter is used. However any number or combination of the additional parameters may be used. If all of the criteria are met, then downhole tool 18 is activated in step 49.
