摘要
白涧铁矿区地层复杂多变,褶皱、断裂极为发育,使得钻探施工难度大。根据其地层条件,采用了多种钻探工艺技术,包括弹子式单管钻进、PDC绳索取心钻进、跟管钻进、金刚石绳索取心钻进。根据地层条件不同,采取了不同的冲洗液配制方案,在施工过程中灵活配合使用,取得良好的效果,顺利完成了预期任务。取得了明显的经济效益并积累了经验。
The various complex formations with folds and fauhs development made the drilling construction very difficult in Baijian mining area, several drilling technologies are adopted, including ball-down single pipe drilling, PDC wire-line core drilling, drilling with casing and diamond wire-line core drilling. According to the different formation conditions, different slurry preparation schemes are adopted and flexibly used in the construction process with good construction effects and experience.
