Definitions

  • the present invention relates to a reamer stabilizer for drilling oil wells.
  • This mechanism causes a lateral shift causing a real stair step in the longitudinal profile of the well.
  • This irregularity can block the passage of the tool if it occurred in front of the tool in a part already drilled during a descent of the rod train. If it occurs behind the tool or behind a stabilizer, it brakes and can even irreparably block the ascent of the drill string.
  • the blockage manifests itself firstly by an increase in pulls, the torque, a loss of rotation, then a jamming upwards, then in case of excessive efforts a jamming downwards.
  • the jamming generally manifests itself during the ascent of the drill string, by blocking the stabilizers which are at the nominal diameter of the hole.
  • Incidents of this type encountered during drilling result in significant loss of time, a few weeks or months on certain drilling, which translate into additional capital costs for drilling barges of up to several million francs.
  • the present invention therefore relates to a reamer stabilizer which allows to reinforce ground accidents in the well during the ascent of the drill string.
  • the invention provides a stabilizer having a true cutter system which includes reinforced and retractable blades.
  • FIG. 1 is a schematic sectional view of an oil well
  • FIGS. 2A and 2B are the sections of a well with landslides
  • Figures 3A and 3B present the details of the stabilizer and the bore system.
  • Figure 1 shows the general section of an oil well (1) with the drill string (2), the stabilizers (3) which serve to center the rods between the walls of the well (4).
  • the drill string ends with the drilling tool (5).
  • FIG. 2A represents the section of a well with a sliding of the grounds (6) on a clay layer (7).
  • FIG. 2B shows the same sliding phenomenon, with the stabilizer (3) jamming against a stair step (8) when raising the drill string.
  • the stabilizer can only pass this obstacle if the stair tread is drilled up by the improved stabilizer object of the invention.
