摘要:
A screen assembly for use within a wellbore. The screen assembly may include a primary screen filter and a base pipe. The base pipe may be positioned within the primary screen filter such that an annular space is formed between the primary screen filter and the base pipe. The base pipe may include a plurality of secondary screen filters positioned along an axial length of the base pipe such that particulates from an inflowing fluid stream from the wellbore create a sand bridge in the annular space if the primary screen filter becomes damaged.
