Simulation and experimental investigations of ultrasonic-assisted drilling with Micro-PDC bit
(Elsevier, 10.02.2023)
articleUltrasonic-assisted drilling (UAD) technology is a new drilling technology, which combines polycrystalline diamond compact (PDC) bits and performs better than conventional PDC drilling in improving the rock-breaking ... -
Simulation and Experimental Study on Rock-Breaking Mechanism of the Reverse Rotary Torque Self-balancing Dual Drill Bit
(Springer, 07.03.2023)
articleThe stick–slip vibration of a drill bit in oil and gas drilling causes significant disturbances to the formation, severely impacting the drilling quality. The dual drill bit (DB) torque self-balancing drilling technology ... -
Study on Wear Resistance of Nickel Cladding Layer with Imitation Shell Convex Strip Structure on the Surface of 7075 Aluminum Alloy Drill Pipe
(MDPI, 27.07.2023)
articleIn this study, a nickel cladding layer with a bionic convex strip structure was applied to the surface of an aluminum alloy drill pipe, and laser cladding technology was used to improve the wear resistance of the aluminum ... -
Wear Resistance Study of Bionic Pitted Ni Cladding Layer on 7075 Aluminum Alloy Drill Pipe Surface
(MDPI, 13.10.2023)
articleTo enhance the lifespan of drill pipes and minimize wear, this study introduces a bionic structure model inspired by the pit shape structure found in the dung beetle’s abdomen. The stress distribution and wear of bionic ... -
双钻头自平衡钻进系统用多通道连续缆管设计
(China Coal Research Institute, 04 / 2023)
articleThe problems, such as low drilling efficiency, large disturbance to the hole wall and long assistance time of tripping caused by the “long arm jurisdiction” drive of the ground drilling rig to the underground drill bit, ... -
钻孔救援连续缆管储放设备研制
(China Coal Research Institute, 03 / 2023)
articleThe double-bit bionic self-balancing continuous drilling technology has the advantages including requiring no drilling rig, high drilling speed and slight disturbance to the borehole wall. It is one of the key potential ...
