管井填砾层的设计对井的质量与寿命关系极大,填砾层的设计与施工不当,往往造成相当大的损失。本文是根据1979年地质部技术座谈小组与美国贝克公司座谈的部分资料以及美、英、苏等国多年来发表的有关研究成果编译的,其中很多结论与我国的试验结果近似,可供生产与设计参考。

The design of tube well gravel layer has a great relationship with the quality and longevity of the well. The design and construction of the gravel layer are often improper, often resulting in considerable losses. This article is compiled based on the 1979 symposium by the Department of Geology and the Baker Company of the United States and some relevant research results published by the United States, Britain and the Soviet Union over the years. Many of the conclusions are similar to the experimental results in China and are available for production and Design Reference.
