| Abstract: | According to the difficulties of water well repairing and gravel-filling for horizontal well, porcelain granule precoated 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. |
