地方病高发区成井用胶质水泥浆的试验研究

Test Study on Colloid Cement Slurry for Well Construction in High Prevalence Area of Endemic Disease

摘要:

通过地方病高发区成井用胶质水泥浆的试验研究，以普通水泥和膨润土为基本材料，同时添加改善材料性能的外加剂，研制了一种用于高砷、高氟、高矿化度地区水井成井的止水材料，具有流动性好、抗渗性高、不收缩、完全无毒、价格低廉等特点，特别是其高抗渗性和不收缩性非常适合地方病区成井时隔离劣质含水层，保证优质含水层与劣质含水层互不串通、不渗漏、不污染。

Abstract:

A kind of water-sealing material used for well completion in high arsenic, high fluoride and high mineralization area was developed with good liquidity and high permeability resistance; no shrinkage, non-toxicity and in low-price. And the high permeability resistance and no shrinkage are very suitable to isolate the inferior aquifer in prevalence area.
