| 摘 要： | PDC钻头有着较高的钻进效率，一直受到客户们的青睐，但它受所钻地层、孔深和温度等因素的制约，使得钻头切削齿寿命较低。最近几年，国内外专家针对如何提高切削齿性能开展了诸多研究，并取得了不少成绩。主要介绍了美国史密斯钻头的2项最新PDC切削齿技术——锥形聚晶金刚石复合片和ONXY 360旋转切削齿。实钻试验表明，采用这2种新型切削齿技术的PDC钻头，钻进效率和寿命都有了明显提高。

| Abstract: | Polycrystalline diamond compact bits have been popular with the customers for the high drilling efficiency. However, the service life of PDC bits have been restricted by stratum, hole depth and temperature. In recent years, many researches were carried out on improving the performance of cutters by experts both in China and abroad and a lot of achievements were received. This paper mainly introduces 2 new technologies of Smith bits-CDE and ONYX 360 degree rotary cutter. The practical drilling experiment shows that the drilling efficiency and service life have been obviously improved by using these 2 cutters. |
