摘要
针对第四系覆盖层、粉细砂地层成井中存在的问题,结合携砾过滤器的研制,试验并探讨了滤料层厚度与阻砂性的相关关系,初步得出了不同规格滤料理论最小阻砂厚度值。
According to the difficulties in well completion in quaternary overburden and silt ＆ fine sand layers, and by the development of gravel-filled filter, the paper tested and discussed the correlation between thickness of filter material and sand-resistance, minimum theoretical thickness value of sand - resistance with different specifications of filter materials was preliminary obtained.
