摘要:

经过50多年的高速发展,聚晶金刚石复合片(Polycrystalline Diamond Compact, PDC)钻头的设计制造技术日臻成熟,现已成为全球油气钻探工程不可或缺的核心破岩工具。当前,中国油气勘探开发正加快向纵深发展,岩石致密难钻已成为深层超深层钻井工程面临的最大挑战之一,对长寿命高效破岩PDC钻头的依赖程度日益上升。但是,国内外PDC钻头技术的发展速度已经趋缓,似乎进入了“瓶颈”阶段,尚未出现颠覆性技术创新。国内外现有钻头产品还无法满足万米深地的钻进需求,亟需研发高效破岩新材料新技术。文章重点梳理了PDC钻头设计制造关键技术的研究现状,归纳了国产钻头存在的短板问题,分析了未来发展趋势,并提出了相应建议。

Abstract:

After more than five decades of rapid development, the design and manufacturing technologies of polycrystalline diamond compact (PDC) bits have become mature, and they have become dominant tools for rock cutting in global oil and gas drilling engineering. Currently, oil and gas exploration and development have accelerated in China, and difficult tight rock drilling has become one of the biggest challenges faced by deep and ultra-deep drilling engineering. The dependence on PDC bits featuring long service life and efficient rock cutting is increasing day by day. However, the development of PDC bit technologies in China and abroad has slowed down and seems to have reached a bottleneck stage, without any disruptive technological innovation. The existing bit products in China and abroad fail to meet the drilling needs of depths of more than ten thousand meters, so it is urgent to develop new materials and technologies for efficient rock cutting. This article sorts out the research status of key design and manufacturing technologies of PDC bits, summarizes the drawbacks of bits made in China, outlines future development trends, and proposes corresponding suggestions.

Key words: PDC bit, polycrystalline diamond compact, heterodont teeth, bit design with composite architecture, next-generation super-hard materials for rock cutting
