Technical Field

Background
A fracture-dense zone geological drilling corer is a device specifically designed to retrieve cores from fracture-dense formations during geological drilling. The main application scenario of such coring devices is in areas of complex geological structure, rock fracture and fracture development, which often present significant challenges to conventional coring methods due to poor rock integrity. Fracture-dense zones generally refer to geological areas where there are a large number of fractures and fracture zones in the rock. These fissures and fracture zones may be formed by a variety of geological effects such as crust movement, stress relief and magma activity. In geological drilling, these areas often suffer from core breaking and collapse, which makes it difficult to obtain a complete core sample. To address this problem, coring devices have been designed that are specifically used for fracture-intensive geological drilling. Such corers typically have greater drilling capacity and higher core grasping force to effectively retrieve the core from the fracture-dense formation. In addition, such corers are also typically equipped with advanced core protection systems that protect the integrity of the core during drilling and prevent the core from being damaged during removal. In summary, a fracture-dense zone geological drilling corer is a device specifically designed to acquire cores in areas of complex geological architecture, rock breaking and fracture development. The method has important application value in the fields of geological exploration, resource development, scientific research and the like.
