由武汉地质学院探矿系研制的低温电镀人造金刚石钻头,最近在美国克里斯坦森公司与该公司生产的金刚石钻头进行了实验室对比试验。试验结果表明,我国研制的这种新型钻头,钻进时效比克里斯坦森公司用热压法生产的金刚石钻头高出近一倍,其他各项技术指标均达到满意的效果。 The low-temperature electroplated synthetic diamond bit, developed by the Geological Prospecting Department of Wuhan Institute of Geology, was compared with the diamond drill bit recently produced by Christensen Corporation in the United States. The test results show that the new drill developed by our country has nearly doubled the drilling time compared with the diamond produced by Christensen by hot pressing, and all the other technical indexes have achieved satisfactory results.
