西部特殊景观区钻探取样技术展示

Summary of Drilling Sampling Tech. at Special Sightseeing Areas in West China

针对西部特殊景观区海拔高、地势险峻、地形地质条件复杂、自然条件恶劣、地理位置偏远、交通不便等问题 ,我国科研人员经过多年努力 ,开发并完善了一批适合于特殊景观区的钻探技术———空气组合钻探技术、水文水井泡沫增压钻探技术、复杂地层钻探取样新技术、液动潜孔锤钻进技术、特殊地层取样钻机及钻探工艺、节水钻探新技术、新疆吐鲁番铀矿勘探及罗布泊环境科学钻探用取样工艺、西部特殊景观区资源勘查及重大建设工程中地质灾害监测和防治新技术、存储式多点连续测斜仪等 ,介绍了各项新技术的原理、研究进展及取得的成果。

Being dead against the problems of high altitude, rugged topography, sophisticated geological conditions, severe natural conditions, remote geography location and inconvenient traffic in special sightseeing areas of west China, the researchers and engineers in our country developed, through several year efforts, a batch of drilling techniques suitable for special sight area, including air combined drilling technology, water well drilling technology with foam pressure increase, complicated formation sample drilling technology, hydraulic down hole hammer drilling technology, sampling rig and drilling techniques in special formations, environment drilling techniques, water save drilling technology, geological disaster control technology, memory multi-shot deviation measurement device, and so on. The work principles of above technology, research advancement and achievement were introduced briefly.
