电镀人造金刚石钻头试用效果探讨

Testing Effect of Electroplated Artificial Diamond Drilling Bits

详细介绍了低温电镀人造金刚石孕镶钻头在“打滑”地层中试用比热压人造金刚石和热压天然金刚石孕镶钻头技术经济效益高的情况，分析了该种钻头时效高、成本低、胎体磨损快，缘于电镀工艺特点和胎体合金成分诸因素，提出了在钻进中防止过快磨损的措施和途径。

It is shown in this paper that low-temperature-electroplated artificial diamond impregnated drilling bits are much more e-conomical than hot-pressing natural diamond impregnated ones when they are used in hard formation drilling.The features ofthis kind of bits,such as higher effectiveness, lower cost and quick wearing of their matrices,are mainly caused by a special elec-troplating technics and the composition of matrices.Measures to prevent matrices from quick wearing are also put forward.
