  • One type of system utilizes electrical signals to select from among multiple well tools for operation of the selected tool or tools.
  • Another type of system utilizes pressure pulses on hydraulic lines, with the pulses being counted by the individual tools, to select particular tools for operation thereof.

  • Each control module includes a selecting device and a fluid metering device. The selecting device compares pressure on one of the hydraulic lines to a reference pressure source.
  • the well tool assembly associated with the selecting device is selected when the pressure on the hydraulic line is greater than the reference pressure by a predetermined amount, but differs from the reference pressure by less than another predetermined amount.
  • the predetermined amounts may be determined by relief valves of the selecting device interconnected between the hydraulic line and the reference pressure source.

  • the fluid is transferred via a different output of the control module, so that the actuator may be operated in a chosen manner by selecting which of the pumps is to be used. Selection of the pump to use is accomplished by merely applying a greater pressure to one ofthe hydraulic lines as compared to the other hydraulic line after the well tool assembly has been selected.
  • Each of the pumps includes a metering chamber having a known volume.
  • a known volume of fluid may be transferred to the actuator, in order to produce a known displacement of a piston of the actuator.

  • the hydraulic control unit 40 is of the type well known to those skilled in the art which is capable of regulating fluid pressure on the hydraulic lines 36, 38.

This determination is accomplished by comparing the pressure on the hydraulic line 46 with a reference pressure source 52.
  • the reference pressure source 52 is an annulus in the well external to the tubular string 34.
  • the selecting device 48 compares the pressure on the hydraulic line 46 to hydrostatic pressure in the annulus 52 to determine whether the control module 42 is selected for operation of its corresponding actuator 22.
  • the selecting device 48 includes two shuttle valves 54, 56 and two relief valves 58, 60.
  • the shuttle valve 54 is normally open and is biased to the open position by a spring 62.

Only when both of the shuttle valves 54, 56 are open is fluid flow permitted from the hydraulic line 46 to the fluid metering device 50 for operation of the actuator 22. Thus, the control module 42 is selected for operation of its corresponding actuator 22 when both of the shuttle valves 54, 56 are open.
  • Fluid pressure on the hydraulic line 46 biases a shuttle 66 of the valve 56 to the left as viewed in FIG. 2, which is toward an open position of the valve.
  • FIG. 4 depicts the configuration of the control module 42 when pressure on the hydraulic line 46 has exceeded the annulus 52 pressure plus the pressure rating of the relief valve 60, the shuttle 66 being displaced to the left and opening the valve 56.
  • the shuttle valve 54 includes a shuttle 68 which is displaced to the left as viewed in FIG. 2 to close the valve. Pressure on the hydraulic line 46 must exceed the pressure on the annulus 52 plus the pressure rating of the relief valve 58 for the shuttle 68 to displace to the left.
  • the relief valve 58 is used in the control module 42 to set an upper limit pressure by which the pressure on the hydraulic line 46 must not exceed the pressure on the annulus 52 for the control module to be selected.
  • control module 42 pressure on the hydraulic line 46 must exceed the annulus 52 pressure plus the pressure rating of the relief valve 60, and must not exceed the annulus pressure plus the pressure rating of the relief valve 58.
  • different control modules 42 may be configured to have different ranges of pressures at which the individual control modules are selected.
  • the control module 24 ofthe tool assembly 12 in the method 10 may be configured so that it is selected when the pressure on the hydraulic line 38 is between 500 and 1,000 psi greater than the annulus 52 pressure
  • the control module of the tool assembly 14 may be configured so that it is selected when the pressure on the hydraulic line 38 is between 1,500 and 2000 psi greater than the annulus pressure, etc.
  • each of the well tool assemblies 12, 14, 16, 18 may be independently selected by merely varying the pressure on the hydraulic line 38.
  • the fluid metering device 50 is responsive to a differential between the pressures on the hydraulic lines 44, 46 to shift a spool valve 70 between one configuration in which fluid is metered from the hydraulic line 46 in response to alternating fluid pressure increases and decreases on the hydraulic line 44, and another configuration in which fluid is metered from the hydraulic line 44 in response to alternating fluid pressure increases and decreases on the hydraulic line 46.
  • pressure on one of the hydraulic lines 44, 46 is varied to transfer fluid from the other hydraulic line to the actuator 22.
  • the hydraulic line on which the pressure is alternately increased and decreased determines whether a piston 72 of the actuator 22 is incrementally displaced to the right or to the left as viewed in FIG. 2.
  • Displacement of the piston 72 in increments is particularly useful where, as in the method 10, the actuator 22 is included in a well tool assembly used to variably restrict fluid flow therethrough. That is, incremental displacement of the piston 72 may be used to incrementally vary the rate of fluid flow through any of the tool assemblies 12, 14, 16, 18, so that the flow rate may be optimized for each ofthe associated zones 26, 28, 30, 32.
  • FIG. 5 depicts the configuration ofthe control module 42 when the module has been selected (i.e., pressure on the hydraulic line is within the range defined by the relief valves 58, 60) and pressure on the hydraulic line 46 exceeds pressure on the hydraulic line 44. Note that a spool 74 of the valve 70 is shifted to the left as viewed in FIG. 5.
  • FIG. 3 depicts the configuration of the control module 42 when the module has been selected and pressure on the hydraulic line 44 exceeds pressure on the hydraulic line 46. Note that the spool 74 is shifted to the right as viewed in FIG. 3.
  • the hydraulic line 44 is in fluid communication with a fluid metering chamber 78 having a floating piston 80 therein.
  • the metering chamber 78 is also in fluid communication with the hydraulic line 46 via a check valve 82, which permits flow from the hydraulic line 46 to the metering chamber, but prevents flow from the metering chamber to the hydraulic line 46.
  • a spring 84 biases the piston 80 upward, in a direction to draw fluid into the metering chamber 78 from the hydraulic line 46.
  • An output of the metering chamber 78 is also in fluid communication with one side of the piston 72 in the actuator 22. It will be readily appreciated that, when pressure above the piston 80 overcomes pressure below the piston in the metering chamber 78 plus the biasing force of the spring 84, the piston 80 will displace downward, and fluid in the chamber will be forced into the actuator 22, thereby displacing the piston 72 to the right as viewed in FIG. 3. Since the metering chamber 78 has a known volume, the amount of fluid transferred from the metering chamber to the actuator 22 is known and produces a known displacement of the piston 72.
  • pressure on the hydraulic line 44 is increased so that it exceeds pressure on the hydraulic line 46 (thereby shifting the spool 74 to the right), and is further increased until the biasing force ofthe spring 84 is overcome and the piston 80 is displaced downward.
  • pressure on the hydraulic line 44 is decreased, thereby permitting the spring 84 to displace the piston 80 upward and drawing further fluid into the metering chamber 78 from the hydraulic line 46.
  • pressure on the hydraulic line 44 should not be decreased to a level where it is less than pressure on the hydraulic line 46, or the spool 74 would shift to the left.
  • the hydraulic line 46 is in fluid communication with a fluid metering chamber 76 having a floating piston 86 therein.

  • pressure on the hydraulic line 46 is increased so that it exceeds pressure on the hydraulic line 44 (thereby shifting the spool 74 to the left), and is further increased until the biasing force of the spring 90 is overcome and the piston 86 is displaced downward.
  • pressure on the hydraulic line 46 should not be increased to a level where it is outside the control module 42 range of selection pressure determined by the selecting device 48.
  • pressure on the hydraulic line 46 is decreased, thereby permitting the spring 90 to displace the piston 86 upward and drawing further fluid into the metering chamber 76 from the hydraulic line 44.
  • pressure on the hydraulic line 46 should not be decreased to a level where it is less than pressure on the hydraulic line 44, or the spool 74 would shift to the right, and pressure on the hydraulic line 46 should not be decreased to a level where it is outside the control module 42 range of selection pressure determined by the selecting device 48.
  • a preferred mode of selectively actuating the well tool assemblies 12, 14, 16, 18 is to increase pressure on both of the hydraulic lines 36, 38, until the pressure is within the selection pressure range of at least one of the control modules 24.
  • more than one control module 24 may be selected at one time, if desired, depending upon the pressure ratings of the relief valves in the selecting devices of the control modules.
  • selection of the control module(s) 24 may be accomplished using pressure applied to only one of the hydraulic lines 36, 38 (for example, the hydraulic line 46 ofthe control module 42 embodiment depicted in FIGS. 2-5), if desired.
  • Pressure on one of the hydraulic lines 36, 38 is then made greater than pressure on the other of the hydraulic lines to thereby determine the manner of operating the associated actuator.
  • Pressure on the hydraulic line 36 or 38 (whichever had the greater pressure thereon to determine the manner of operating the actuator) is then alternately increased and decreased to thereby transfer known volumes of fluid incrementally from the other hydraulic line to the actuator, producing incremental displacements of a piston ofthe actuator.

  • the restrictor 94 permits only very gradual equalization of pressure between the hydraulic line 46 and the accumulator 92.
