提高金刚石钻进“打滑”岩层生产效率的措施

自从我国推广应用金刚石钻进技术以来，就如何提高金刚石在钻进坚硬、致密、弱研磨性岩层(“打滑”岩层)的效率进行了许多研究。文章比较了电镀和孕镶金刚石钻头在该类地层防“打滑”的研制情况，确定孕镶钻头是解决“打滑”岩层并提高生产效率的最佳选择。

HOW TO IMPROVE THE EFFECTIVENESS OF DIAMOND DRILLING THROUGH MASSIVE AND HARD TO CUT LAYER

A lot of research work has been done concerning the improvement of the effectiveness of diamond drilling through the massive and hard to cut layer since the diamond drilling technology was introduced to China. It is confirmed that the pregnanted drill bit should be given first priority for the solution of slipping layer to improve the effectiveness, compared with the electroplated bit in preventing slipping while cutting through the layer.
