江西省地矿局九○一地质大队为提高湖南衡东盐井1500m钻孔的钻进效率、保证孔内矿芯的完整性,成功配置出无固相饱和盐水泥浆,替代了原来使用的低固相盐水泥浆。该泥浆配方是专门针对盐井钻探和小口径绳索取芯钻探技术而配置,其中加入了抗盐处理剂,成功攻克了普通处理剂无法溶于盐水的技术难题。同时,钻探过程中钻杆内无泥皮形成,较大程度上减小了孔
In order to improve the drilling efficiency of the 1500m borehole in Hengdong Salt Mine in Hunan Province and ensure the integrity of the ore core in the hole, the Geological Brigade of Jiangxi Province Geological and Mineral Resources Bureau successfully configured a solid-free saturated salt water slurry instead of the low solidified Phase salt water slurry. The mud formulation is specially configured for salt well drilling and small-caliber cord coring drilling technology, adding a salt-resistant treatment and successfully addressing the technical challenges of being unable to dissolve common salt in saline. At the same time, there is no mud in the drill pipe during drilling, to a great extent, the holes are reduced
