Research status and development trend analysis of broad-spectrum diamond bit at home and abroad.

With the consumption of shallow resources on the earth, the exploration and development of resources are constantly marching to the depth, and the conditions of strata encountered are becoming more and more complicated. Hard and dense formations, strong abrasive formations, and other complicated strata conditions have been a major hindrance to deep drilling. The diamond bits are widely used in geological resource development. Therefore, the comprehensive performance requirements of diamond bits are also increased. However, the existing diamond bits can only be applied to a certain formation and need to be replaced frequently, therefore, the research and development of broad-spectrum diamond bits with excellent formation applicability, high drilling efficiency, and long bit life is an important part of overcoming the deep drilling tasks. In recent years, the diamond drill bit has been developed rapidly, the structure, category, and performance have been greatly improved, and there also exists a certain improvement space. Therefore, this paper introduces the research status and important achievements of broad-spectrum diamond drills in recent years, including the improvement and application of drill structure and matrix performance, and then puts forward the research problems and future development direction of diamond drills with respect to the existing research results of broad-spectrum diamond drills. By summarizing the development trend of broad-spectrum diamond bits in this paper, the new research direction of diamond bit making technology and application field was revealed, which is of reference significance to the research and development of broad-spectrum diamond bits in the field of oil and gas exploration and mineral resources development.
