Securing layers in a well screen assembly |
摘要 |
A well screen assembly includes an elongate base pipe, a shroud layer about the base pipe, and a mesh layer between the shroud layer and the base pipe. A portion of the mesh layer overlaps another portion of the mesh layer to form an area of overlap. A spine is positioned proximate substantially an entire length of the area of overlap, and transmits a force from the shroud layer to the mesh layer that compresses and seals the area of overlap against passage of particulate. |

1. A well screen assembly, comprising:
an elongate base pipe; a shroud layer about the base pipe; a mesh layer between the shroud layer and the base pipe, a portion of the mesh layer overlaps another portion of the mesh layer to form an area of overlap; and a spine, discrete from all other layers of the screen assembly, proximate substantially an entire length of the area of overlap and transmitting a force from the shroud layer to the mesh layer that compresses and seals the area of overlap against passage of particulate, wherein the spine has a c-shaped cross-section. |
