陶粒贴砾过滤器的研制与应用

Development of Porcelain Granule Precoated Well Screen and the Application

摘要:

针对水井修井和水平井成井填砾困难的特点，通过大量室内试验，研制了陶粒贴砾过滤器。该过滤器以PVC-U塑料管作衬管、陶粒作滤料，经粘合剂粘结而成，具有滤水阻砂效果好，整体质量轻，韧性好，滤层的抗压、抗冲击强度高等优点。介绍了陶粒贴砾过滤器的基本性能特点和应用效果。

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.
