Definitions

  • the invention relates generally to well interventions. More specifically, the invention relates to apparatus and method for guiding a downhole tool through a wellbore having wellbore restrictions.
  • stiff being defined in terms of bending moment
  • a relatively stiff tool string e.g., a tubular string or a stiff well logging tool string
  • the lower end of the stiff tool string can be prevented from going further into the wellbore if it lands against a washout or ledge formed as explained above.

  • Another challenge related to such spoolable rods is that the well equipment operator cannot visually or otherwise determine if the lower end of the rod is moving or not. Failure to determine such movement while the surface end of the rod is being inserted into the wellbore can cause the equipment operator to continue pushing the rod into the wellbore against a stopped lower end of the rod, causing damage to or failure of the rod.

If the readout of the vibration sensor 132a at the surface indicates no vibration, the operator may conclude that the lower end of the downhole tool 120 is not moving and may stop insertion or retraction of the downhole tool 120 into or from the wellbore before physical damage to the downhole tool 120 or wellbore takes place.

  • the indexing system 138 can deflect the lower section 136 relative to the upper section 134 through a set of preset angles, e.g., 0°, 45°, 90°, 120°, without decoupling the lower section 136 from the upper section 134.

Removing axial load from the downhole tool 120 can cause the indexing system (138 in FIG. 2) to orient the hole finder 136 to an outward angle with respect to the longitudinal axis of the downhole tool 120, as shown in FIG. 4.
  • the operator can increase fluid pressure in the interior of the downhole tool 120 to cause the indexing system 138 to orient the hole finder 136 to an outward angle as described above.

  • orientation of the hole finder 136 after the activation described above may be such that the guide tool 124 becomes lodged in a later restriction 146 (such as a reduced-diameter section) in the wellbore 100, thereby preventing the downhole tool 120 from advancing along the wellbore 100.

  • the operator may cause the hole finder 136 to return to the previous angle (or centered/neutral position) by releasing pressure from the interior of the downhole tool 120.
  • the hole finder 136 is reoriented, the operator can move the downhole tool 120 along the wellbore once again. If the downhole tool 120 hangs up once again in the wellbore 100, the hole finder 136 can be activated as described above to orient the hole finder 136 to a next outward angle, e.g., 45° from the previous angle. Activation of the hole finder 136 can be repeated as necessary to engage one or more of a number of different angle settings, for example, 0°, 45°, 90°, and 135° (where 0° may represent the neutral/centered position).
  • a guide tool may provide a wellbore equipment operator to avoid tool damage, and to continue operations in a wellbore having obstructions with minimum delay.
