提高金刚石取芯钻头寿命是提高整个矿产勘探效率的重要途径之一,特别是深孔钻探施工时,多采用高胎体金刚石取芯钻头。本实验首先利用热压法加工金刚石孕镶块,然后加工自带多层水口和水槽的新型钻头钢体,最后采用镶焊法将金刚石孕镶块与钻头钢体焊接在一起。试制的2只?75/54.5 mm金刚石取芯钻头,工作层高度达到22 mm。野外实验证明：该钻头使用寿命分别达到86 m 和93 m,比现场使用的普通金刚石取芯钻头,使用寿命分别提高120%和141%。
提高金剛石取芯鑽頭壽命是提高整箇礦產勘探效率的重要途徑之一,特彆是深孔鑽探施工時,多採用高胎體金剛石取芯鑽頭。本實驗首先利用熱壓法加工金剛石孕鑲塊,然後加工自帶多層水口和水槽的新型鑽頭鋼體,最後採用鑲銲法將金剛石孕鑲塊與鑽頭鋼體銲接在一起。試製的2隻?75/54.5 mm金剛石取芯鑽頭,工作層高度達到22 mm。野外實驗證明：該鑽頭使用壽命分彆達到86 m 和93 m,比現場使用的普通金剛石取芯鑽頭,使用壽命分彆提高120%和141%。

An important way to improve overall drilling efficiency is to extend the life of single bit,especially using high matrix diamond bits in deep hole.Impregnated diamond blocks were manufactured by using hot pressing method,and then new drill bit steel body including multi-layer nozzle and waterway was processed,at last the impregnated diamond blocks and new drill bit steel body were combined by insert-welded processing. Two ?75/54.5 mm diamond coring diamond drill bits were developed,the height of work layer was 22 mm. Experimental results showed that the life of two drill bits was 86 m and 93 m,respectively,improved by 120%and 141% compared with the conventional impregnated diamond bit.
