当前,金刚石钻进复杂地层钻孔护壁堵漏的新课题,已为国内外有关科研单位和地质勘探部门高度关注。我院地质系探工教研室最近研制成功的MY—1型和MY—1A型无固相冲洗液以及LSX—2型数字式钻孔流速流向仪不仅为这一领域提供了解决某些难题的新手段,也为我国自力更生利用资源等方面开创了新局面。 MY—1型和MY1—A型无固相冲洗液,通过实践证明,用于地质岩心钻探,对于一般水敏性地层和坍塌、破碎不稳定地层的钻进,能够提高钻速和起到良好的钻孔护壁作用。
At present, the drilling of complex layers of diamond wall plugging a new topic, for domestic and foreign relevant scientific research units and geological exploration department attention. The newly developed MY-1 and MY-1A Solid-Phase Fluids and the LSX-2 Digital Drill Flow Velocity Meter recently developed by the Department of Geology and Prospecting at the Institute of Geology in our hospital not only provide new opportunities in this area to solve certain problems Means, but also for our own use of resources and other resources to create a new situation. MY-1 and MY1-A solid-free rinsing fluids have proven to be used in geologic core drilling to improve penetration and perform well for water-sensitive formations and for collapsing and fractured unstable formations Drilling wall role.
