FABRICATION OF DOWNHOLE DRILLING TOOLS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240308920 titled 'FABRICATION OF DOWNHOLE DRILLING TOOLS

Simplified Explanation:

The abstract describes a method of forming a composite cutter for a downhole drilling tool using a mixture of polycrystalline diamond powder and cubic boron nitride powder, without the need for a catalyst. The mixture is placed into a mold, exposed to ultra-high-pressure, high-temperature treatment, and then cooled to form the composite cutter.

  • The method involves mixing polycrystalline diamond powder and cubic boron nitride powder in a specific molar ratio to form a catalyst-free composite mixture.
  • The composite mixture is placed into a mold shaped like a cutter.
  • The mixture undergoes an ultra-high-pressure, high-temperature treatment to form a solid composite body.
  • The solid composite body is then cooled to create the composite cutter.

Key Features and Innovation:

  • Formation of a composite cutter without the need for a catalyst.
  • Specific molar ratio of polycrystalline diamond powder and cubic boron nitride powder.
  • Ultra-high-pressure, high-temperature treatment process.
  • Mold shaping for the composite mixture.

Potential Applications:

  • Downhole drilling tools.
  • Mining equipment.
  • Cutting tools for industrial applications.

Problems Solved:

  • Eliminates the need for a catalyst in forming composite cutters.
  • Provides a method for creating durable and high-performance cutting tools.

Benefits:

  • Enhanced durability and performance of composite cutters.
  • Cost-effective manufacturing process.
  • Versatile applications in various industries.

Commercial Applications:

Original Abstract Submitted

a method of forming a composite cutter for a downhole drilling tool is described. the method includes: mixing a polycrystalline diamond powder and a cubic boron nitride powder with a molar ratio between 0.1 and 0.9 to form a catalyst-free composite mixture; placing the catalyst-free composite mixture into a mold configured in a shape of a cutter; exposing the catalyst-free composite mixture to an ultra-high-pressure, high-temperature treatment including a pressure between 11 gigapascals (gpa) and 20 gpa, and a temperature between 1300 kelvins (k) and 2600 k to form a solid composite body; and cooling the solid composite body to form the composite cutter.
