Definitions

  • the present invention relates to the field of petroleum exploitation, and more particularly to an expandable sand screen.
  • the expandable sand screen technology is a new merging sand control technology, in which a sand control screen expands its diameter during downhole construction. This technology was first applied to the Oman Thayfut5 well. After it is put into production, the sand control effect was proved.
  • An expandable sand screen includes an inner pipe, an intermediate pipe fixedly sleeved on the inner pipe, and an outer pipe fixedly sleeved on the intermediate pipe, where a plurality of slots is distributed on a wall of the inner pipe, the intermediate pipe is formed by a wire-like object that is wound spirally, and a plurality of holes is distributed on a wall of the outer pipe.
  • the slots on the inner pipe have a length of 20 to 100 mm and a width of 1 to 10 mm, and are evenly distributed on the wall.
  • the holes on the wall of the outer pipe are round holes having a diameter of 5 to 20 mm, elongated holes having a length of 5 to 30 mm and a width of 1 to 10 mm, or elliptical holes, and are evenly distributed on the wall.
  • a distance between two ends of the inner pipe is longer than the
  • intermediate pipe (2) and the outer pipe (3) one end being provided with an external thread and the other end being provided with an internal thread.
  • the size of sand particles to be filtered can be precisely controlled.
  • the expanded diameter increases the drainage area and reduces the oil flow resistance, increasing the daily crude oil production per well by 30-50%.
  • the maximum sealing pressure of the casing is sealed to withstand a pressure of 50 MPa, so as to ensure the quality of well cementing.
  • an anchor may be provided to fix the hanger at the bottom.
  • a liquid adhesive is provided for the expandable hanger at the top so as to ensure the reliability of circumferential sealing.
  • the expansion resistance is balanced between the porous section and the connection section of the sand screen, and the circumferentially continuous layer of the sand screen forms a statically determinate arch structure, which has a high overall structural rigidity and is stable and durable and not subject to deformation and damage. 6. After downhole expansion, the gap in the stainless steel wire that forms the intermediate pipe can be controlled.
  • FIG. 1 is a schematic structural view of the present invention.
  • the slots on the inner pipe 1 have a length of 60 mm and a width of 5 mm, and are evenly distributed on the wall. Two ends of the slot are rounded to provide a smooth transition.
  • the intermediate pipe 2 is formed by a stainless steel wire that is wound continuously and spirally.
  • a distance between two ends of the inner pipe 1 is longer than the intermediate pipe 2 and the outer pipe 3, one end being provided with an external thread and the other end being provided with an internal thread, so that a plurality of inner pipes 1 can be connected to each other.
  • This solution is not only applicable to drilling of petroleum wells, but also is applicable to drilling of other wells and geothermal wells as required.

Abstract

Selon l'invention, un filtre à sable extensible comprend un tuyau intérieur, un tuyau intermédiaire emmanché de façon fixe sur le tuyau intérieur, et un tuyau extérieur emmanché de façon fixe sur le tuyau intermédiaire, une pluralité de fentes étant distribuée sur une paroi du tuyau intérieur, le tuyau intermédiaire étant formé par un objet ressemblant à un câble qui est enroulé en spirale, et une pluralité de trous étant distribuée sur une paroi du tuyau extérieur. La taille des particules de sable à filtrer peut être maîtrisée précisément ; le diamètre étendu augmente la zone de drainage et réduit la résistance à l'écoulement de pétrole, et la production quotidienne de pétrole brut est augmentée de 30-50 % par puits.
