Environmental and Scientific Drilling is defined as "combining the drilling-engineering and environment-science, utilizing the dirlling equipments and technology to realize the intention of sampling and environmental controlling" .
环境科学钻探，是指将钻探工程和环境科学结合起来，利用钻探工程的设备、工艺技术来实现环境科学调查研究取样、进行环境治理目的的科学钻探方法。
5) resources and environmental scientific drilling
资源环境科学钻探
1.
Because of the characteristics of low consolidation degree,fracture,water-bearing,deformation and dissolution;according to the difficult coring,serious diameter reducing,borehole wall unconsolidation,interlayer high confined brine and natural gas in resources and environmental scientific drilling in Chaidamu Basin,it is important to improve coring efficiency and protect borehole wall.
为应对柴达木盆地资源环境科学钻探工程项目施工地区岩层中固结程度松软、碎脆、富水、易变形、怕冲刷及易溶蚀等特点,钻进中不易采取岩矿心,钻进粘土及淤泥时缩径严重,孔壁不稳定及地层内广泛分布着层间高承压卤水和天然气,极易发生涌水或井喷的问题,机械岩心深孔钻进施工中合理解决岩心采取率低,护孔压井防喷,是确保科学钻探工程顺利实施的关键点。
