Analysis of the phenomenon of slipping when drilling rigs drill into mudstone or sandstone. When drilling rigs drill into mudstone or sandstone, they often slip. That is, there is no resistance and no pressure, and it is impossible to drill or it is difficult to drill, thus affecting the construction progress and production efficiency. After a long period of construction and experience accumulation, I have also worked on many mudstone geological foundation construction projects, such as: Hubei Tianxingzhou, Jialingjiang, Miluo and other projects. I have certain understanding and insights into drilling mudstone. Through the understanding of geological drilling tools and operations, Integration finally solves the problem of mudstone drilling
Mudstone overview Mudstone, sandy mudstone, argillaceous sandstone, sandstone and shale and other sedimentary rocks are red, dark red or brown because they contain rich oxides. These rocks Collectively referred to as red sandstone, red sandstone mainly has two typical structural forms: granular clastic structure and muddy cementation structure. Most red sandstones can be disintegrated and broken by the atmospheric environment, or even muddy. Therefore, the size and particle gradation of their rock blocks will be Changes with the time course of the dry-wet cycle. Mudstone is a sedimentary rock solidified from mud and clay. Its composition is similar to that of shale but is less brittle. A kind of claystone with inconspicuous bedding or lamination. Mudstone has the ability to absorb water. , bonding properties
