A new high-efficiency, long-life diamond drill bit has been successfully developed by Guilin Diamond Industry Co., Ltd. for two years. Its service life is twice that of conventional drill bits, and its drilling efficiency is 30% higher than that of conventional drills. The latest weapon. This drill bit applies the new pre-alloyed powder to the diamond bit matrix. The cold press-hot press process is used to produce a single-layer nozzle high-carb diamond bit with a significantly improved bit body strength and a working layer of more than 20 mm. After the successful development of the new high-tire diamond bit, it was tested in the Yunnan Dulong drilling project. The results show that in the VII-VIII (7-8) grade sandstone, the drilling efficiency of the product exceeds 3 m / h and the service life exceeds 400 meters, 1.3 times and 2 times respectively for conventional diamond drill bits; in VIII-IX (8-9) grade granite, the drilling efficiency exceeds 1.5 m / h and the service life exceeds 150 m, which is 1.2 times that of conventional diamond drill bits. And 2 times.
In deep drilling engineering, bit quality is a key factor affecting drilling schedule and cost. According to Zhou Tiansheng, chief engineer of Guilin Diamond Industry Co., Ltd., the test shows that the new high-tire diamond drill can completely replace the imported products, and the cost performance is higher than that of the imported drill bit. It is a tool for comprehensively implementing deep engineering and exploring large-scale resources in a large scale. . At present, the drill has been used in deep drilling projects by several drilling companies in Yunnan and Sichuan provinces.
