| 中文摘要:自从20世纪80年代PDC复合片研发成功以来，PDC钻头由于其钻进性能强和耐磨性能好，在世界许多国家的石油钻井和地质勘探中得到了广泛应用，取得了很好的效果。但是，如何进一步提高其在钻探工程中的技术经济指标是一个很迫切的问题。俄罗斯博士Скоромных В. В.教授等对此进行多年研究，提出了稳态破碎岩石方式的思想，即在轴载和扭矩切力形成的合力R与切削面成垂直角度条件下，切入深度h不变时形成的一种碎岩方式。并在此基础上提出了一些设计PDC钻头方面的建议。 |

| Abstract:Since PDC（Polycrystalline Diamond Compact）was developed successfully in 1980s, PDC drill bit has been widely applied in petroleum drilling and geological exploration in many countries due to its good penetration ability and wear resistance, and very good results have been obtained. However, how to further improve its technical and economic indicators in drilling engineering becomes a very urgent problem. Russian doctor of technical sciences professor Скоромных В. В. and some others have studied this problem for many years and put forward an idea of stabilized mode of rock fragmentation, that is a rock fragmentation method under the condition that the resultant force R held together by axial load & torque sheering force and the cutting surface are perpendicular to the angle with the constant cutting depth. On this basis, some suggestions on PDC bit design are presented. |
