钠土泥浆在构造破碎带型复杂地层钻进中的应用

Application of Sodium Slurry in Drilling in Structure Fractural Zone of Complex Formation

摘要:

应用钠土泥浆,解决了锡坑矿区复杂地层钻进中运用其它措施难以解决的塌、漏、掉等问题，保证了后续施工的钻孔质量，提高了钻进效率和经济效益。通过钠土泥浆与钙土泥浆及其它无固相冲洗液类比分析，得出了钠土泥浆在该矿区取得好成效的机理。针对赣南构造破碎带型复杂地层钻进中存在的问题，借鉴锡坑矿区的成功经验，提出应重视对钠土泥浆的研究和应用的建议。

Abstract:

By the analogy analysis on the comparison among sodium slurry, calcium slurry and other solid-free washing fluids, it was proved that sodium slurry had the mechanism for good drilling effect in complex formation of tin mining area. With this successful experience, suggestion was made on laying stress on study and application of sodium slurry.
