摘　　要：长期以来,管井过滤器直径和长度确定一直是管井工程未完全解决的理论和实践课题,迄今,有关规定不同,存在学术见解分歧,也存在诸多值得讨论的问题。该文概述了国内外关于管井过滤器直径和长度的规定,并进行了分析和讨论,探讨了存在问题的原因。在此基础上,提出了管井过滤器直径和长度确定的原则。The determination of diameter and length of tube well filter is always a problem not being completely solved for a long time in tube well engineering from theoretical and practical point of view. Upto now some regulations of them are quite different. This paper briefly introduced regulations about diameter and length of tube well filter inside and outside China. Based on discussion of the problem the princple of determination of diameter and length of tube well filter is put forward
