AI Technical Summary
Existing drill bits lack sufficient wear resistance and impact toughness in drilling deep, ultra-deep, and long horizontal wells, resulting in low drilling efficiency and high costs. They are also prone to damage, especially in complex formations, making it difficult to meet the requirements for long service life and efficient drilling.
Polycrystalline diamond composite material is used to prepare honeycomb structured segments through 3D printing. Combined with high temperature and high pressure process, polycrystalline diamond composite material is formed for the working part and support part of the drill bit, which improves wear resistance and impact toughness.
It greatly improves the wear resistance and impact toughness of the segments, extends the service life of the drill bit, meets the drilling needs of complex formations, and is suitable for deep-sea, deep-well and long-horizontal shale gas extraction.
