AI Technical Summary

Problems solved by technology

The existing problems are that the mechanical drilling method takes a long time to complete the drilling, consumes a lot of energy, and the drilling cost is high
The hydrothermal fragmentation drilling method has a short completion time, consumes a lot of energy, and the drilling cost is doubled. There is no way to share the drilling cost. Therefore, the research and development drilling completion time is short, the drilling cost is low, and it is safe and reliable for practical application. Drilling methods and drilling tools (devices) become problems to be solved

Description

technical field [0001] The invention relates to an underground drilling engineering tool. Background technique [0002] In the era without modern tools, the ancestors of human beings created and invented the technological methods of burning pine trees to burn mountains and pouring river water to break rocks and build roads according to the observation and learning of nature. In 1521, China drilled the first oil well in Jiazhou, Sichuan. In 1840, a 1,200-meter-deep well was drilled in the Ziliujing area of ​​Sichuan. In 1835, the first 1,000-meter deep-sea well was drilled. Today, experts, engineers, and scientists have invented various underground drilling methods and modern drilling tools. They are divided into mechanical drilling methods, physical drilling methods and chemical drilling methods. The mechanical drilling methods include rotary drilling, sudden drilling and percussion rotary drilling. Physical drilling methods include vacuum fragmentation drilling, laser ...
