贴砾过滤器贴砾层渗透性试验研究OA
Experimental study on permeability of the pre-packed layer in pre-packed screen pipe
贴砾过滤器、砾石充填在地热开采、水文观测等工程中得到了广泛应用.他们的主要工作部位为贴砾层、充填层,研究最常用的贴砾材料石英砂的渗透性能.通过调节砂样的粒径、细颗粒含量,测试砂样固结前后在饱和状态下的渗透性,分析粒径、级配对砂样固结前后渗透性的影响,通过试验数据整理,分析相同条件的砂样固结前后的渗透性能差异.试验表明,固结前后的砂样的渗透系数随粒径的减小而减小,在中砂范围内变化最大,在细砂范围变化较小;固结前后砂样的渗透系数都随着细颗粒含量的增多…查看全部>>
Pre-packed screen pipes and gravel packing are widely used in geothermal exploitation,hydrological observation and other projects.The main working parts are gravel layer and pre-packed layer.In this paper,the permeability of quartz sand was researched which is commonly used as the pre-packed material.Through adjusting the particle size and fine particle content of the sand samples,the permeability of quartz sand before and after consolidated in saturated sta…查看全部>>
