The pre-packed screen is mainly composed of an outer screen, an inner screen, a pre-packed gravel layer and a center tube. The single-layer wire-wrapped screens with different diameters are welded together, and the annular space formed by the double-layer screens is tightly filled with quartz sand in advance and then compacted and sealed to form a multi-layer sand retaining barrier to prevent formation sand from entering the production wellbore. Play the role of sand control. Gravel filling and high-temperature cementation are completed on the ground, which is convenient for construction, can reduce construction time, easy post-treatment, and quick effect. The effect is obvious. In addition, the double-layer pre-filled screen has high compressive strength, high permeability, and large flow area, which is suitable for ordinary vertical wells and inclined wells.
