| 中文摘要:：PDC 钻头在石油天然气钻井和地质勘探钻进中得到了广泛的应用，取得了很好的技术经济效果。但是，钻进中产生的PDC切削具非正常磨损，影响了这种先进方法的机械钻速和钻头进尺的提高。俄罗斯史密斯钻头（Smith Bit）公司研发出了一种钻进过程中可以沿着自身轴线回转的切削具ONYX，抑制了PDC切削具的非正常磨损，这是一种创新，具有实用价值。Нескоромных B.B.教授等对镶有这种切削具的钻头的结构和性能参数进行了分析研究。试验表明，这种ONYX切削具的耐磨性比常规固定式PDC切削具的耐磨性好，钻头钻进效果也比较好，俄罗斯有关地质勘探的队正在积极推广使用，值得引起我们的注意。 |

| Abstract:PDC bits are widely used in oil and gas drilling and geological exploration drilling. and good technical and economical results have been obtained. However，abnormal wear of the cutting element in drilling engineering affects the improving of technical and economic effectiveness of the advanced drilling method. Company Smith drill bit of Russia has developed a new cutting element, rotating around its inner shaft，inhibiting the wear of PDC cutting element. It is a new innovation and has practical significance. Prof Neskoromnyh V.V.et al have analysed and researched on design and characteristic parameters of the bit with ONYX. Finished tests show, that the wear resistance of the ONYX is better than, that of the fixed PDC element. The result of drilling using such bit are better and the bits are being used actively in geological and prospecting organizations of Russia. It is worth for us to pay attention to. |
