川西甲基卡锂矿3000 m科学深钻关键技术探讨

Discussion on key technology for the 3000m deep scientific drillingproject of Jiajika Lithium Mine in west Sichuan

摘要:

川西甲基卡锂矿3000 m科学深钻项目地处川西高海拔地区。根据工程技术要求，设计三开钻孔结构，选用经济实用的钻探设备，主要包括HXY9型钻机、K2790型钻塔、BW300/16型泥浆泵等。分析和制定拟采用的钻进工艺和取心方法、钻具组合、冲洗液方案等是必不可少的工作。同时为践行“绿色勘查”理念，应制定措施，保障施工期间施工地生态环境受到保护。

Abstract:

The 3000m deep scientific drilling project of Jiajika Lithium Mine in west Sichuan is located in the high-altitude areas of western Sichuan Province. According to the technical requirements, the borehole is designed with three drilling sections. A set of economical and practical drilling equipment was used, mainly including HXY9 drill rig, K2790 drilling tower,BW300/16 mud pump. Drilling technology, the coring method, the drilling assembly and the drilling fluid plan were examined and developed. For implementation of the concept of green exploration, necessary measures have been developed to protect the ecological environment of the construction site.
