· A gravel pack is simply a downhole filter designed to prevent the production of unwanted formation sand. The formation sand is held in place by properly sized gravel pack sand that, in turn, is held in place with a properly-sized screen. To determine what size gravel-pack sand is required, samples of the formation sand must be evaluated to ...
· The screening at this time is called prescreening. For sand and gravel processing plants, pre-screening can avoid ineffective crushing of materials, thereby increasing the production capacity of crushing equipment and reducing power consumption. A soil-leakage feeder or a special vibrating screen is ideal pre-screening equipment.
