摘要
结合地质测量的工程实例,详细介绍了大孔径瓦斯抽放井在下套管过程中地质测量工作不可替代的重要作用,为类似工程施工积累了宝贵经验。
The important role of geological survey to casing running in large aperture gas drainage well is introduced in detail associated with geological survey engineering example,which accumulates precious egineering experiment for the similar one.
