| Abstract:In deep hard rock strata, the pregnant diamond drill bit has high strength, high wear resistance and impact resistance, which has better drilling performance in such strata. The efficiency and life of pregnant diamond drill bit are closely related to the performance of broken rock unit. This paper summarizes the research status of wear and reinforcement of pregnant diamond bit unit, summarizes and analyzes the influence of different reinforcement methods on cutting unit strength, wear and drilling efficiency, discusses the direction of reinforcement of pregnant diamond bit unit suitable for deep hard rock drilling from the perspective of life extension and efficiency, and provides reference for the design and manufacture of pregnant diamond bit for deep geological drilling. |
