GRAVEL PACKER ASSEMBLY AND METHOD

摘要

A packer and screen assembly for a gravel or filter-packed well including a cylindrical shaped screen and a packer ring attached to an upper portion of the screen, with the packer ring positioned above an annular space surrounding the cylindrical-shaped screen and including an access opening having a closed configuration that substantially closes off the annular space and an open configuration that permits access to the annular space to fill the annular space with gravel or filter material. A method of filling or refilling a well with gravel or filter pack material is also provided including the steps of accessing the packer and screen assembly positioned within the well, transitioning the access opening in the packer ring from the closed configuration to the open configuration, and delivering gravel or filter pack material through the access opening and into the annular space surrounding the cylindrical-shaped screen.
