Single action dual tube core drilling tools are mainly used in the following fields:
1. Geological exploration: In mineral resource exploration, it is used to drill and obtain underground rock samples, analyze geological structure and mineral distribution. When searching for metallic minerals such as gold, silver, and copper, as well as non-metallic minerals such as coal mines, it is possible to ensure the integrity of the collected rock cores, providing a basis for geologists to determine mineral reserves, grades, and other factors. In terms of geological hazard assessment, such as studying the causes of disasters such as landslides and mudslides, high-quality rock cores obtained through this drilling tool can help analyze the stability of geological formations and the physical and mechanical properties of rocks.
2. Water conservancy engineering: used for geological exploration of dam foundations, shoulders, and other parts in the construction of water conservancy projects such as reservoirs and dams. The drilling and coring of inspection holes in the grouting project of Baiyin Wuchuan Reservoir have greatly improved the core recovery rate and met the design technical requirements through this drilling tool. In the construction of hydropower stations, geological drilling is carried out in the selected area to understand the geological conditions, provide geological data for the design and construction of the project, and ensure the safety and stability of the project.
3. Oil and gas exploration: In the exploration and development of oil and gas, it is used to obtain underground core samples, analyze the lithology, porosity, permeability and other parameters of the formation, help determine the location, thickness and properties of oil and gas reservoirs, and provide a basis for the development plan of oil and gas fields. For example, in the third drilling of the "Songke Second Well", a large-diameter single action double tube drilling tool with a diameter of 311 millimeters was used, and a rock core with a diameter of 214 millimeters was successfully obtained, providing technical support for the field of ultra deep drilling.
4. Research field: In Earth science research, it is used to obtain core samples at different depths, study the evolution history of the Earth, ancient environmental changes, etc. A complete core sample allows researchers to conduct high-precision testing using microscopes, chemical analysis instruments, etc., providing reliable first-hand information for related research. In the research of disciplines such as rock mechanics and soil mechanics.
