SYSTEM AND METHOD FOR FILTERING SAND IN A WELLBORE |
摘要 |
A technique enables long-lasting filtering of fluid flow in a wellbore. The technique employs a base pipe and a sand control screen surrounding the base pipe. The sand control screen has a support layer, a filter media surrounding the support layer, and a protective shroud. At least one of the support layer and the protective shroud layer utilizes longitudinal ribs held in place by a transverse wire. The components of the sand control screen cooperate to provide a simple but durable system for long term filtering of sand from fluid flow in a wellbore.
