Wire-line coring is a widely used non-coring technology. For large-depth straight-hole coring drilling, it is a time-consuming process for wire-line coring to go in For the horizontal hole or near-horizontal hole, it is a difficult and time-consuming process to insert the wire-line coring dredger. On the basis of wire-line coring technology, a coring tool for recovering inner tube assembly and core by hydraulic lifting is developed in this paper! The development and application of cordless hydraulic lifting coring drill tool can replace the existing method that the coring drill tool needs a special winch to send/fish the inner pipe assembly, and simplify the coring drilling equipment and coring process, effectively improve the coring efficiency, for the large depth straight hole and horizontal hole coring drilling technology to open up new ideas.
