A gravel pack screen is 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 determine the median grain size diameter and grain size distribution. The quality of the sand used is as important as the proper sizing.
Stainless Steel 304 Double layer Gravel Pack Screen are manufactured by a v or wedge shaped wire around an internal array of longitudinal support rods.The world advanced all-weld technology is used with each intersecting point of these wire fusion welded,which creates the robust construction and excellent mechanical performance.The v or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening,hence the screen allows water (oil) to enter your well freely in ample quantities,while at the same time keeps the majority of sand and gravel out of the well.The slots can be changed according to different strata.
The objective of all sand exclusion techniques is to arrest the movement of formation sand into the well. Sand production can cause erosion of well equipment, well restrictions, and sand deposits in flowlines and other surface installations.
In the case of gravel packing, the gravel should be placed directly against the formation so that formation grains loosened from the rock can be arrested immediately. As the production exerts forces in the direction of the well bore, the gravel should be packed against the formation face and the pack itself should be without voids to prevent the gravel (and formation sand) to move.
A third requirement for gravel is that the pack should be tight. The grains of the gravel should rest on each other in such a way that the grains cannot move or re-arrange themselves during production.
Features, Advantages and Benefits
The prepack screen also called gravel pack screen which has larger collapse strength than rod based well screen.
Save more value and drilling process than to use the rod base well screens.
The media will help the contractors and the well owner to washing the wells easier.
The wide range of diameters (1-1/4 to 20 in.) and connections,weld rings or threaded fittings,
Provides flexibility for meeting most application needs with a variety of standard or custom-end fittings-offering easier adaptation for a wide array of uses.
