摘要
根据溪洛渡地层硬、脆且存在层间层内错动、裂隙发育和较强研磨性的特点 ,着重就金刚石钻头胎体和烧结工艺进行研究 ,研制出热压孕镶金刚石钻头 ,以提高钻进效率 ,缩短钻探施工工期 。
The Xiluodu formation is hard and fragile, contains interlayer and intrastratal faults, and is of comparatively great grindability. According to these specific characteristics, the diamond bit crown and its sintering technology are studied in particular. As a result, a type of hot pressed, impregnated diamond bit has been developed to meet the needs of increasing the drilling efficiency and shortening the time limit for drilling construction for the sake of the accomplishment of hydroelectric station construction.
