Definitions

  • DESCRIPTIVE REPORT OF THE PATENT OF INVENTION "CUTTING PROCESS TO SIZE RLPS AT GROOVED TUBES FOR PETROLEUM ABSTRACTION IN HORIZONTAL AND VERTICAL WELLS”.
  • the current invention is related to a cutting process to size rips in grooved tubes for petroleum abstraction in horizontal and vertical wells, most precisely it's a technologic newness at these rip cutting process, being unaware of similar patented or currently used procedures.
  • vertical and horizontal tubes are inserted in the wells. Axial cuts are made at the tube surface, through whose will pass the embezzled liquid.
  • DRAWING 01 A perspective view of a tube, pointing its lateral rip; presenting the details of a cut made by this process, a comparative view between the straight rip and the new rip made by this process.
  • the cutting process to size rips in grooved tubes for petroleum abstraction in horizontal and vertical wells attends to the basic newness and industrial applications necessary items for the patent approval.
  • DRAWING 02 Detail about the semi conic rip
  • the cutting process to size rips in grooved tubes for petroleum abstraction at horizontal and vertical wells will allow cuts with the desired size. Opposing to the later situation when abrasive discs made the cuts, this system will operate with laser.
  • the laser technology allows controlling and programming, the user will decide about the size and opening angle of the rips, and at horizontal tubes specifically the rip will be trapezoidal, with the entrance size (I) minor than the exit size so, in the case of granulated residue aspiration it will only find resistance at the outside edge of the rip (I).
  • the opening angle is divergent, after the grain pass the resistance it will follow the aspirated hquid.

Abstract

L'invention concerne un procédé de découpage dont la caractéristique principale est la substitution des disques de découpage laser classiques qui permettent de pratiquer des entailles sur des tubes rainurés d'extraction pétrolière dans des puits horizontaux et verticaux. L'effet principal de ce procédé est de modifier les entailles droites en leur donnant une forme conique. Il est ainsi possible d'éviter que des résidus solides ne bloquent les entailles, ce qui arrive fréquemment avec les entailles droites et pratiquement jamais avec les nouvelles entailles.
