俄气石油开发并成功测试新的超硬材料

据俄罗斯油气网7月1日莫斯科报道，俄罗斯天然气工业石油公司(俄气石油/Gazprom Neft)的科技中心已经成功完成了钻头刀片原型的试验，这种新钻头刀片是用一种新的超硬材料五硼化钨制成的。这种独特材料的设计是应俄气石油要求，它比目前用于制造钻头的其他材料的硬度强30%，耐高温能力是后者的两倍。

这个开发项目是俄气石油专家和来自俄罗斯科学院斯科尔技术研究所和韦列什哈金高压物理研究所专家的共同努力。在项目的初始阶段，由Artyom Oganov教授领导的来自斯科尔技术研究所的研究团队使用其专有的数字算法USPEX来预测具有所需性能的新型超硬材料。

接下来，俄罗斯科学院高压物理研究所合成并检测了新的预测化学结构。这种化合物被命名为五硼化钨。今天，另一个项目阶段已经成功完成：新材料被用于制造和测试切削盘——未来钻头刀片的原型。

在花岗岩上进行了试验，试验结果表明，新材料的硬度比碳化钨及其替代品高出30%。此外，五硼化钨比碳化钨更耐高温，能承受高达2200摄氏度的高温。

俄气石油科技中心首席执行官哈萨诺夫表示：“新材料钻头的成功开发证明了我们与研究和学术伙伴的有效合作。我们致力于联合开发项目来应对与油气行业和许多其他行业分支高度相关的挑战。”

Gazprom Neft developed and successfully tested new superhard materials

Neftegaz.RU. Gazprom Neft’s Science and Technology Center has completed successful trials with a prototype of drill bit blades for drilling equipment that are made from a new superhard material, tungsten pentaboride. The design of this unique material was ordered by Gazprom Neft, and it is 30% stronger and twice more resistant to high temperatures than its alternatives used to manufacture the drill bits today.

The development project was a joint effort of Gazprom Neft experts and specialists from Skoltech and Vereshchagin Institute for High Pressure Physics of the Russian Academy of Sciences. At the initial stage of the project, a research team from Skoltech guided by Professor Artyom Oganov used its proprietary digital algorithm USPEX to predict that new superhard materials with desired properties.

Next, the new predicted chemical structures were synthesized and examined by the Institute for High Pressure Physics of the Russian Academy of Sciences. The compound was named tungsten pentaboride. Today, another project phase has been successfully completed: the new material was used to manufacture and test the cutting disks - prototypes of the future drill bit blades.

The trials were carried out with granite and showed that the new material is 30% stronger than pobedit (tungsten carbide) and its alternatives. Moreover, tungsten pentaboride has resistance to high temperatures than that of pobedit and can withstand temperatures up to 2200 degrees Centigrade.
