摘要
通过吉林省长白县沿江矿区地层施工实例,介绍了在全孔布满大小裂隙及溶洞地层钻进中,有针对性地对施工的结构、下入套管的程序及措施、钻具级配、钻进方法、钻进参数、冲洗液的配制及管理等方面进行细致的设计,并在堵漏工艺方面研究多种方案,取得了很好的效果。
Through the construction practice of Yanjiang mining area,Changbai County,Jilin Province,introduced drilling working in the hole with fissure and cave formation targeted design some aspects in construction structure,procedures and measures of casing,drilling tool assembly,drilling method,drilling parameters,preparation and management of drilling fluid,and research a series of plan on plugging technology,and obtained better results.
