| Abstract: | Reservoir construction is a key technology for commercial exploitation of high-temperature geothermal energy of dry and hot rocks, and carbon dioxide blasting and cracking technology provides new ideas for this purpose.The article briefly describes the carbon dioxide blasting and cracking technology, as well as the relationship between the carbon dioxide charge, the amount of activator, and the thickness of the constant pressure tablet during the blasting process. Focused on improving carbon dioxide fracturing for the construction of dry and hot rock reservoirs, designing the specific parameters inside the fracturing device, and optimizing the entire external structure and system,and finally developing a carbon dioxide cracker that can be used for the construction of dry thermal rock reservoirs,which provides effective technical means for the construction of dry and hot rock reservoirs, and fills the gap in the field of high temperature and high pressure underground carbon dioxide crackers. |
