| 摘 要： | 通过西藏罗布莎科学钻孔施工过程冲洗液应用实践，结合现场试验室试验情况及实际生产过程中使用的泥浆类型、配方、性能特点、使用情况，总结出适合罗布莎铬铁矿区易坍塌、破碎、漏失、缩径等复杂地层钻探施工的冲洗液配方，并对不同类型冲洗液使用情况及存在的不足进行了阐述，对同一配方冲洗液在不同钻探工艺条件下使用所取得的不同效果做出了说明，为今后坍塌、破碎、漏失、缩径等复杂地层深部钻探的冲洗液配方选择提供了一些参考。

| Abstract: | By the application practice of flush fluid for scientific drilling in the Luobusa of Tibet, combining field laboratory tests and mud type, mud formula, performance characteristics and its use in the actual production process, a flush fluid for-mula is summarized, which suits for complex formations of collapse, broken, serious leakage and hole diameter shrinkage in Chromium iron mining area of Luobusa.The paper elaborates the application of different flush fluids and the existing short-comings;explains the different effects of mud with the same formula in different drilling conditions, which provide some ref-erences to the selection of flush fluid formula for deep drilling in complex formations. |
