若尔盖铀矿田复杂地层泥浆技术研究与应用

Research and Application of Mud Technology in Complex Formation of Ruoergai Uranium Mining Field

摘要:

若尔盖铀矿田地层极其复杂，主要表现为强水敏性、强破碎、漏失严重，钻探施工难度极大。本文结合地层特点及孔壁稳定性分析，研究出了适合于该矿区复杂地层钻探施工的泥浆体系，并在现场取得了良好的应用效果，同时也总结出了一套泥浆现场维护与管理技术措施，对类似复杂地层钻探施工中的泥浆技术具有较好的借鉴作用。

Abstract:

The formation of Ruoergai uranium mining field is extremely complex, mainly manifesting with high water sensitivity, strong broken and severe leakage, which result in high difficulty of drilling operation. In this article, combining the analysis on formation characteristics and the hole wall stability, the mud system suitable for the complex formation drilling in mining area is obtained, and good application results achieved in site. And a set of technical measures of mud maintenance and management are summarized in the application, which can be good reference for mud technology in similar complex formation drilling construction.
