Definitions

  • the present invention relates to an erosion resistant sand screen having a sleeve or cover formed from an erosion resistant microporous material.
  • producing zones to allow produced fluids to enter the casing bore.
  • formation sand from unconsolidated formations may be swept into the flow path along with produced fluids. This sand is relatively fine and causes erosion of tubing, downhole equipment and surface equipment.
  • the well bore is uncased, and an open face is established across the producing zone, in particular, in horizontal well completions.
  • formation sand from unconsolidated formation may be swept into the flow path along with produced fluids.
  • one or more sand screens may be installed in the flow path between the production tubing and the producing zone(s).
  • a packer may be set above and below the sand screen to seal off the annulus in the producing zone from non-producing zones of the formation.
  • the annulus around the screen may be packed with a relatively coarse sand or gravel which acts as a filter to reduce the amount of fine formation sand reaching the screen. Nethertheless, the remaining sand contained in the produced fluids may impinge on a screen with sufficient velocity so as to cause erosion of the screen. As the velocity of the flow of the produced fluids is increased the rate of erosion also increases. Where the fluid flow rate from one portion of the formation is greater than the fluid flow rate from another portion of the formation, the screen will erode more rapidly opposite the high flow rate portion than it will opposite the lower flow rate portion.
  • EP 0 999 345 relates to a tortuous path sand control screen for filtering particles out of fluid produced from a wellbore that is capable of withstanding severe downhole conditions during installation and production and that experiences low rate of erosion during gravel packing, frac packing or production.
  • the tortuous path sand control screen comprises a base pipe and a screen wire wrapped around the base pipe such that the turns of the screen wire extend along at least a portion of the length of the base pipe and form gaps therebetween.
  • the screen wire has a profile that reduces the velocity of particles travelling through the gaps.
  • the profile of the screen wire channels the particles to loose energy and velocity.

  • the profile of the screen wire may channel the particles in a multi-arcuate path.
  • US 5,829,522 describes a screen provided with a tubular base pipe and a filtering portion.
  • the filtering portion is externally disposed relative to the base pipe and outwardly overlaps an opening formed radially through the base pipe.
  • the filtering portion thus, filters fluid flowing radially though the opening.
  • the filtering portion may be a tubular filtering portion made of, for example, spirally wrapped and generally triangular cross-sectioned wire.
  • the screen also includes a support material positioned between the base pipe and filtering portion and, thus helps prevent the filtering portion from being radially inwardly collapsed by radially inwardly flowing fluid.
  • the screen also includes a coating exteriorly applied to the filtering portion. The coating may perform one or several functions including preventing erosion of the filtering portion.
  • the filtering portion is partially or completely exteriorly covered with a coating.

  • the coating is preferably applied after the screen is otherwise completely assembled.
  • US 4,064,938 relates to a sand screen assembly for oil and gas wells.
  • the assembly has a heavy-walled, erosion resistant deflector around the wire screen to deflect the stream of fluid entering the wellbore, thereby substantially reducing the erosion of the wire screen.
  • the assembly comprises an inner section of perforated pipe, at least one layer of wire screen positioned around the pipe, and a stream deflecting means having an erosion resistant wall at least one-fourth inch thick positioned around the layer of wire screen.
