Definitions

  • Embodiments described herein generally relate to downhole tools. More particularly, such embodiments relate to a screen assembly for use during gravel packing in a wellbore.
  • Gravel packing generally involves running a base pipe into the wellbore.
  • a screen is wrapped around the section of the base pipe positioned adjacent to the hydrocarbon- producing formation.
  • a gravel slurry including gravel particulates dispersed within a carrier fluid, is pumped down a work string and into the annulus formed between the screen and the wall of the wellbore.
  • the carrier fluid flows through the screen and back up to the surface while the gravel particulates remain disposed in the annulus between the screen and the wall of the wellbore.
  • the gravel particulates are used to filter and separate the sand from the hydrocarbons as the hydrocarbons are being produced from the formation.
  • voids tend to form in the gravel particulates between the screen and the wall of the wellbore.
  • the void presents a path of lesser resistance for the hydrocarbons and the sand to flow through the screen and into the base pipe, resulting in sand being produced to the surface and the screen being more exposed to damage from, for example, erosion.
  • What is needed is an improved system and method for gravel packing an annulus between a screen and wall of a wellbore.
  • the screen assembly may include a base pipe having an axial bore formed therethrough.
  • An axial rod may be positioned radially- outward from the base pipe.
  • a screen may be positioned radially-outward from the axial rod.
  • a housing may be positioned radially-outward from the base pipe and axially adjacent to the axial rod, the screen, or both, and a first annulus may formed between the housing and the base pipe.
  • a first opening may be formed through the base pipe and radially-inward from the housing.
  • a second opening may be formed through the base pipe and radially-inward from the housing, and the second opening may be axially offset from the first opening.
  • a valve may be disposed within the first annulus and positioned axially between the first and second openings. The valve may allow a fluid to flow axially therethrough when in an open position and prevent the fluid from flowing axially therethrough when in a closed position.
  • the screen assembly may include a base pipe having an axial bore formed therethrough.
  • An axial rod may be positioned radially-outward from the base pipe.
  • a screen may be positioned radially-outward from the axial rod.
  • First and second axial channels may be formed between the screen and the base pipe.
  • the axial rod may be positioned between the first and second axial channels.
  • An opening may be formed through the axial rod, between the axial rod and the base pipe, or both, and the opening provides a path of fluid communication between the first and second axial channels.
  • a housing may be positioned radially-outward from the base pipe and axially adjacent to the axial rod, the screen, or both, and an annulus may be formed between the housing and the base pipe.
  • a radial opening may be formed through the base pipe and radially-inward from the housing.
  • An inflow control device may be formed in the base pipe and radially-inward from the housing, and the inflow control device may be axially offset from the radial opening.
  • a valve may be disposed within the annulus and positioned axially between the radial opening and the inflow control device. The valve may allow a fluid to flow axially therethrough when in an open position and prevent the fluid from flowing axially therethrough when in a closed position.
  • a method of gravel packing an annulus between a screen and a wall of a wellbore may include flowing a gravel slurry into the annulus between the screen and the wall of the wellbore.
  • the gravel slurry may include a plurality of gravel particulates and a carrier fluid.

Abstract

L'invention porte sur un ensemble tamis. L'ensemble tamis peut comprendre un tuyau de base ayant un perçage axial formé à travers celui-ci. Une tige axiale peut être positionnée radialement vers l'extérieur à partir du tuyau de base. Un tamis peut être positionné radialement vers l'extérieur à partir de la tige axiale. Un boîtier peut être positionné radialement vers l'extérieur à partir du tuyau de base et axialement au voisinage de la tige axiale, du tamis, ou des deux, et un premier anneau peut être formé entre le boîtier et le tuyau de base. Une première ouverture peut être formée à travers le tuyau de base et radialement vers l'intérieur à partir du boîtier. Une seconde ouverture peut être formée à travers le tuyau de base et radialement vers l'intérieur à partir du boîtier, et la seconde ouverture peut être décalée axialement par rapport à la première ouverture. Une vanne peut être disposée à l'intérieur du premier anneau et positionnée de façon axiale entre les première et seconde ouvertures.
