| 中文摘要:复合片钻头在石油钻井和地质钻探中，得到了广泛应用，取得了很好的技术经济效果。但是，在深孔钻进中，特别是在复杂地层，诸如软硬互层、裂隙互层和研磨性地层中钻进时，机械钻速下降，钻头进尺降低，影响了其进一步推广和使用。如何提高钻头的使用性能，即提高钻头的强度（硬度）和耐磨性，以解决上述问题是一个非常重要的课题。在提高钻头使用性能方面，对其进行低温液态氮处理、磁化处理的综合处理方法是一种很有效的方法。俄罗斯专家进行的理论研究和生产实践证明，使用这种综合方法可以有效提高钻头的使用性能。 |

| Abstract:In petroleum and geological exploration drilling, PDC bits have been widely used with good technical and economical results. But in deep drilling, particularly in complicated formations, such as soft hard alternate formation, fractured formation, abrasive formation, the penetration rate of PDC bits is slow and the bit life is reduced; thus hindering its further promotion and use. How to increase the performance of the bit, i.e. its strength (hardness) and abrasiveness to resolve above mentioned problems is a very important issue. The integrative treatment of PDC bit with cryogenic nitrogen and magnetization is a simple and effective method to increase the performance of the bit. Results of theoretic study and field practices done by Russian specialists show that the bit performance can be increased effectively with the above treatment method. |
