人造聚晶金刚石复合片,在七十年代已在国外被成功地运用于制造石油钻头.特别在全面钻头上,已取得了相当好的经济效果. 我国八十年代初,开始对上述复合片进行研制.首先是被成功地运用在刀具上,后来才在石油钻头上开始试验.这主要是由于石油钻井对这种磨具提出了更严格的性能要求. 1982年10月,我们对锦州碳素厂研制的人造 In the seventies, artificial polycrystalline diamond compact has been successfully used in the manufacture of petroleum drill bits abroad, especially in the comprehensive drill bit, and has achieved quite good economic results.China began in the early eighties the above composite films Developed first successfully applied to the tool, and later began to test the oil drill, mainly due to oil drilling on the abrasive proposed more stringent performance requirements.In 1982 October, we Jinzhou carbon Factory developed man-made
