Development of Porcelain Granule Pre coated Well Screen and the Application
Abstract:According to the difficulties of water well repairing and gravel-filling for horizontal well, porcelain granule pre-coated well screen was developed based on a lot of laboratory tests. PVC-U and porcelain granule were taken as the liner pipe and filter material with outstanding permeability of water and sand-resistance effect. The paper introduced the development process of the porcelain granule pre-coated well screen and the application.
