What are the main characteristics of swivel tube core barrel
2025-02-26The main characteristics of swivel tube core barrel are as follows: 1. High quality coring: During the drilling process, the outer tube drives the drill bit to rotate and break the rock, while the inner tube remains stationary, avoiding mechanical crushing of the rock core caused by friction and vibration generated by the rotation of the drilling tool. This can keep the rock core in its original
