摘要: A technique enables long-lasting control over fluid flow in a wellbore. The technique employs a base pipe, a flow control device, and a sand control screen. The sand control screen is coupled to the flow control device and mounted over the base pipe. Additionally, the sand control screen comprises longitudinal ribs positioned along the base pipe and a filter media positioned along the longitudinal ribs. A protective shroud is mounted over the filter media and cooperates with the other components of the system to provide a simple but durable system and method for controlling fluid flow.

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.
