近年来钻探用超硬材料的发展与展望

Development and prospect of the super hard materials applied to the drilling industry in recent years

摘要:

超硬材料在工业发展中扮演着举足轻重的角色，特别是地质钻探行业中超硬材料的研制与应用更显突出。以前钻探界有句话：“有什么样的磨料就有什么样的钻进设备和钻进工艺”，这充分说明了它们的因果关系。金刚石钻头随着人造金刚石的品种、结构、性能、品质等方面不断提高，很大程度上满足了地质钻探行业的需求，并推动了钻探行业的飞速发展；同样钻探应用中提出的新需求，又不断促进超硬行业继续探索。两者相辅相成，互相促进，共同发展。本文结合大量实例阐述了地质钻探行业中使用的超硬产品的特点、种类、性能等。真切地期待未来超硬材料能够更精更新，更多地在钻探产业实现创新突破。

Abstract:

Superhard materials play an important role in the industrial development， especially in the geological drilling industry， the development and application of superhard materials are more prominent. In the past， the drilling industry has a word saying that the kind of abrasive results in the kind of drilling equipment and craft， which fully explained their causal relationship. As the promotion of the variety， structure， performance， quality of the artificial diamond， the diamond bit has met the needs of geological drilling industry to a large extent， and rapidly promoted the development of drilling industry. In the meantime， the new requirements from drilling applications continue to accelerate further exploration in the superhard industry. In other words， they complement each other， promote each other and develop together. This paper describes the characteristics， types and properties of superhard products used in geological drilling industry according to large numbers of examples. The authors sincerely expect that the superhard materials will be more refined and updated in the future， and more innovation breakthroughs will be achieved.
