Laser Enhancement of Diamond Drill bit insert micro-geometries for Oil and gas Exploration (LEDDOE)

LEDDOE旨在开发一种新型激光应用，以提高石油和天然气钻井应用中聚晶金刚石（PCD）复合钻头的性能。这将通过使用激光烧蚀来优化切削刃来提高钻井性能，从而用更复杂的多面几何形状取代基本几何形状。此外，裂缝衰减将通过激光微钻或切割专门设计的优化3D形状的微图案来实现，以便在钻井作业期间更好地将机械/热负荷分配到块状PCD材料中。

LEDDOE is aimed at developing a novel laser application which enhances the performance of polycrystalline diamond (PCD) composite drill bit inserts for oil and gas drilling applications. This will be achieved by using laser ablation to optimally profile the cutting edges to enhance drilling performance, thereby replacing the basic geometries with more complex, multi-faceted geometries. In addition, fracture attenuation will be achieved by the laser micro-drilling or cutting of specifically designed micro-patterns of optimised 3D shapes placed in strategic locations to better distribute the mechanical/thermal loads into the bulk PCD material during the drilling opeartions.
