Abstract
Sand control screen assemblies can include one or more erosion-resistant modules. One sand control screen assembly includes a base pipe defining one or more flow ports that provide fluid communication into an interior of the base pipe, a well screen arranged about the base pipe and in fluid communication with the one or more flow ports via a flow path extending between the well screen and the one or more flow ports, and an erosion module arranged within the flow path and comprising an erosion-resistant material, the erosion-resistant material being configured to filter a fluid prior to the fluid entering the interior of the base pipe.
Claims8
A sand control screen assembly, comprising:
- a base pipe defining one or more flow ports that provide fluid communication into an interior of the base pipe;
- a well screen arranged about the base pipe and in fluid communication with the one or more flow ports via a flow path extending between the well screen and the one or more flow ports;
- an erosion module arranged within the flow path and comprising:
- an erosion-resistant material selected from the group consisting of ceramic beads, ceramic sphres, a wire mesh, a sintered wire mesh, metal pieces or pellets, sintered metal pieces or pellets, a find sintered wire mesh, pellets or pieces of a metal carbide, and pellets or beads coated with erosion-resistant materials;
- a first retainer disposed within one of the one or more flow ports, the first retainer positioned along the flow path and in between the well screen and the erosion-resistant material, wherein the first retainer comprises one or more perforations that filter fluid flowing along the flow path after the fluid is filtered by the well screen and before the fluid is filtered by the erosion-resistant material;
- and
- a second retainer arranged about the base pipe, wherein the erosion-resistant material is held packed and retained between the first retainer and the second retainer, and wherein the second retainer comprises one or more perforations that filter fluid flowing along the flow path after the fluid is filtered by the erosion-resistant material.
4 more elements
A method, comprising:
- drawing a fluid through a well screen arranged about a base pipe that defines one or more flow ports providing fluid communication into an interior of the base pipe;
- flowing the fluid in a flow path that extends between the well screen and the one or more flow ports;
- after flowing the fluid through the one or more perforations of the first retainer, filtering the fluid in an erosion module arranged within the flow path the erosion module comprising an erosion-resistant material selected from the group consisting of ceramic beads, ceramic spheres, a wire mesh, a sintered wire mesh, metal pieces or pellets, sintered metal pieces or pellets, a fine sintered wire mesh, pellets or pieces of a metal carbide, and pellets or beads coated with an erosion-resistant materials, a first retainer having one or more perforations and positioned along the flow path and in between the well screen and the erosion-resistant material, and a second retainer having one or more perforations, wherein filtering the fluid in the erosion module comprises:
- filtering the fluid through the one or more perforations of the first retainer;
- after filtering the fluid through the first retainer;
- filtering the fluid through the erosion-resistant material;
- and
- after filtering the fluid through the erosion-resistant material, filtering the fluid through the one or more perforations of the second retainer;
- after flowing the fluid in the erosion module;
- conveying the fluid from the erosion module into the interior of the base pipe;
- ejecting the fluid from the erosion module via a first retainer within the one or more flow ports;
- and
- retaining the erosion-resistant materials between the first retainer and a second retainer arranged about the base pipe, wherein the erosion-resistant material is packed between the first retainer and the second retainer.
