摘　　要：西岭勘查区多数钻孔布置在海边,施工过程中,造浆用水为海水或海浸水。传统的淡水冲洗液体系在携带岩粉、润滑钻具、保护孔壁等方面效果不明显,甚至失效,影响了钻探施工的顺利进行。在传统冲洗液材料使用的基础上进行创新,引进新型海水抗盐冲洗液材料,研究了适合该矿区的海水冲洗液配方,使冲洗液体系性能提高,减少了安全隐患,提高了生产效率。Most of the boreholes in the Xiling exploration area are located at the seaside.During drilling,seawater or seawater intruded water is used for slurry making.The traditional fresh water mud system doesn’t perform well or even fail in carrying cuttings,lubricating drilling tools and protecting hole walls,which affects smooth drilling progress.The traditional mud materials were innovated with introduction of new seawater salt resistant mud materials to develop the seawater drilling fluid composition with better performance for the mining area;thus eliminating safety hazards and improving drilling efficiency.
