Polycrystalline diamond composite sheets for deep-sea oil and gas exploration are widely used in the fields of oil and shale oil and gas exploration and development, as well as geological drilling, using independently developed assembly and sintering processes. Our technical team has been engaged in the research and production of polycrystalline diamond composite sheets for deep-sea oil and gas exploration for a long time. In recent years, we have achieved some world advanced technological achievements in this field and have independent intellectual property rights and technological innovation. Polycrystalline diamond composite sheets for deep-sea oil and gas exploration are synthesized by one-time sintering of Sandvik diamond micro powder and hard alloy under high temperature and pressure. The polycrystalline diamond composite sheets used for deep-sea oil and gas exploration have received excellent feedback from multiple domestic and foreign customers. The polycrystalline diamond composite sheets used in deep-sea oil and gas exploration adopt special production and testing processes, which make them have good wear resistance, self sharpening and impact resistance.
