深部钻进用新型复合片钻头的试验研究

Experimental research on a new generation PDC bit used for deep drilling

摘要:

在地质钻探和石油天然气钻井中，尤其是在深部钻进中复合片钻头得到了广泛的应用，取得了很好的技术经济效果。但是，常常发生复合片非正常磨损甚至损坏的情况，影响了其推广使用。俄罗斯钻探工作者在对其进行深入研究的基础上，提出了使用新一代楔形复合片和圆锥弧形复合片组合，设计出新型结构减振复合片钻头，取得了一定的进展，技术经济效果良好。

Abstract:

In geological drilling and oil and gas drilling， PDC bits have been used widely with good technical and economic results. However， PDC bits are often abnormally worn， and even broken， which influences their further popularization and application. Russian drillers studied this problem， and suggested that new generation PDC cutting elements be used to design a new structure bit. Some progress has been made with considerable technical and economic results. Therefore it has definite reference value for Chinese drillers.
