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 Bits)公司研发了一种钻进过程中可以沿着自身轴线回转的ONYX切削具,抑制了PDC切削具的非正常磨损,具有创新性和实用价值。НecкopoMныx B.B.教授等对镶有ONYX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,俄罗斯正在积极推广使用,建议中国有关专家和部门对此进行研究和试验。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(Smith Bits)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 analyzed 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.
