介绍了钻井工程用超硬复合材料（包括ＰＤＣ、ＰＣＢＮ、陶瓷和金刚石膜）的发展现状及前景；同时也介绍了以这些材料切削具的钻头制造及应用情况；指出金刚石膜合成技术的发展已使金刚石膜制造钻井工程用切削具成为可能。
The development status and prospect of superhard composites for drilling engineering (including PDC, PCBN, ceramic and diamond films) are introduced. The manufacture and application of drill bits with these materials are also introduced. The development of diamond film synthesis technology has been pointed out Diamond film manufacturing drilling engineering tools possible.
