摘要
随地球浅层资源消耗殆尽,资源勘探开发不断向深部进军,所遇地层条件愈加复杂,坚硬致密地层、强研磨性地层等复杂地层条件成为深部钻探的重大阻碍。金刚石钻头广泛应用于地质资源开发,因此对金刚石钻头综合性能要求也随之提高,然而现有的金刚石钻头只能适用于某一地层,需要经常更换,因此,研发地层适用性好、钻进效率高、钻头寿命长的广谱性金刚石钻头是克服深部钻探任务的重要内容。近年来,金刚石钻头发展迅速,在结构、品类与性能等方面都得到了较大提升,同时也存在一定提升空间。本文介绍了近年来广谱性金刚石钻头的研究现状与取得的重要进展,包括钻头结构及胎体性能方面的提升及应用,随后针对现有的广谱性金刚石钻头研究成果,提出了金刚石钻头的研究难题以及未来发展方向。通过本文对广谱性金刚石钻头的发展趋势总结,揭示了金刚石钻头制作技术和应用领域的新型研究方向,对我国油气勘探及矿产资源开发领域广谱性金刚石钻头研究有一定借鉴意义。
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.
