摘要
在经济社会高速的发展背景下,地质钻探工程越来越多。工程施工工程中遇到的复杂地质条件越来越多,这极大的增加了地质钻探施工问题的发生,特别是钻孔缩径问题不断出现,不仅引发大量的岩粉。因此,加强地质钻探钻孔缩径的预防与处理具有非常重要的意义。下文结合实践,对小口径地质钻探钻孔缩径的预防与处理展开探讨。
In the context of rapid economic and social development, geological drilling projects are more and more. More and more complex geological conditions are encountered in engineering construction, which greatly increases the occurrence of geological drilling construction problems, especially the problem of borehole shrinkage, which not only causes a lot of rock powder. Therefore, it is of great significance to strengthen the prevention and treatment of borehole shrinkage in geological drilling. The following part discusses the prevention and treatment of bore shrinkage in small-bore geological drilling based on practice.
