The hydraulic motor drives the drill pipe to rotate, the diamond drill bit cuts the rock formation, and the high-pressure mud pump delivers the flushing fluid to the bottom of the hole through the center hole of the drill pipe, cools the drill bit and carries the cuttings back to the surface.
Features of rope coring: When the core fills the coring tube, there is no need to lift the drill. The inner tube assembly (including the core) is lifted out of the drill pipe by the wire rope, and the outer drill pipe continues to remain in the hole.
The salvage is lowered by the winch and docked with the salvage head of the inner tube assembly. The hydraulic winch quickly recovers the inner tube to complete the coring (reducing the drilling time by more than 70% compared with conventional drilling rigs).
After the inner tube is taken out, the spare inner tube assembly is replaced and drilling continues to achieve “continuous coring without lifting the drill”.
①Enhancement of drilling efficiency
In granite formation , the mechanical drilling speed is increased by 40-60%:
Reduction of the number of lifting times of a single hole by 50%.
②Core Quality Assurance
Mud film wall protection reduces hole wall collapse, and core take rate is increased to 92-96%;Compared with clear water drilling, core integrity in fractured strata is increased by 30%.Diamond drill bit life reaches 80-120m under mud lubrication.Energy saving: frequency conversion control reduces the power consumption of pump set by 15-20%.
③ Safety and environmental protection upgraded
Accident rate in the hole decreased: the pressure of the mud column balances the stratum, reducing the risk of water surge and hole collapse;Equipped with waste slurry curing device, which meets the environmental protection standard.
