金刚石作为一种碎岩材料,它具有突出的优越性能。长期以来,人们就把金刚石当作有效的切削研磨材料用之于钻探工作。近十年来,我国也推广使用了金刚石钻进技术,研制了多种金刚石钻头,摸索到许多有效的钻进经验,在硬岩及坚硬岩层钻进中取得了较好的经济效益。金刚石钻进的优越性已逐渐为人们所认识。但是在实践中人们也了解到金刚石作为钻进碎岩工具尚存在有粒度小、抗弯能力差、价格高等不足。 Diamond as a rock material, it has outstanding superior performance. For a long time, people used diamond as an effective cutting abrasive for drilling. In the past ten years, our country also promoted the use of diamond drilling technology, developed a variety of diamond bits, found many effective drilling experience, and achieved good economic benefits in drilling hard and hard rock formations. The advantages of diamond drilling have gradually become known. However, in practice, people also learned that there is still a small diamond particle size, poor bending resistance and high price as diamond drilling tools.
