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

LEDDOE旨在开发一种新的激光应用，以提高用于石油和天然气钻井应用的多晶金刚石（PCD）复合钻头刀片的性能。这将通过使用激光烧蚀来优化切削刃的轮廓以增强钻孔性能来实现，从而用更复杂的多面几何形状取代基本几何形状。此外，断裂衰减将通过激光微钻孔或切割放置在关键位置的优化3D形状的专门设计的微图案来实现，以在钻孔操作期间将机械/热负荷更好地分配到块体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.
