中文摘要:在地质钻探和石油钻井中，钻头都是非常重要的钻进工具。其技术特性，特别是硬度和耐磨性与钻探的技术经济指标，即与机械钻速、钻头进尺和每米钻探成本直接相关。为了提高钻头的工作性能，俄罗斯南方国立技术大学提出了综合低温淬火、磁化回火处理钻头的方法。经过综合处理后，钻头体、复合片底座和钎焊层的硬度分别提高了30%、3%和22%。野外钻进试验结果表明，经过低温液态氮和磁化综合处理的与未经综合处理的钻头相比，每次试验钻头进尺都有提高，总体上钻头进尺提高了222%，取得了很好的钻进效果。并对取得的效果进行了X射线和显微技术分析。

Analytical research on Xray diffraction and electronic microscopic technology used for improving working abilities of bit, treated integratively by cryogenic nitrogen and magnetization
Abstract:In geological drilling and petroleum drilling, the bit is a very important drilling tool. Its technical characteristics, particularly its hardness and wear resistance, is related directly to drilling technical and economical index, i.e. penetration rate, bit footage and drilling cost per meter. In order to improve performance of the bit, South Russian State Technical University has proposed and tested cryogenic nitrogen and magnetization integrative treatment method for the bit. The hardness of the bit body, base of PDC and the solder layer were improved by 30%, 3% and 22% respectively. The field testing results show that the penetration rates of the bit with the treatment of cryogenic nitrogen and magnetization were improved than those of the normal one in each test, and the penetration rate of this type bit increased by overall 222%, achieving good results. Meanwhile, the obtained results were analyzed with Xray diffraction and electronic microscopic technology.
