PVC-U携砾过滤器滤料厚度与阻砂性的相关关系试验研究

Experimental Study on Correlation between Filter Material Thickness of PVC-U Gravel-filled Filter and the Sand-resistance

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。

Abstract:

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.
