Background

At present, geological exploration in China gradually develops towards deep, rock stratums faced by deep drilling are more complex, and requirements on the performance of diamond bits are higher. The traditional method for manufacturing the diamond bit comprises a hot pressing method and an electroplating method, wherein the performance of the diamond bit manufactured by the hot pressing method is difficult to control and is difficult to adapt to drilling of deep complicated and variable strata; the diamond drill bit manufactured by the electroplating method has poor inner and outer diameter protection effects, has short service life, and is difficult to adapt to deep complex strata, particularly non-complete strata and strong-abrasiveness strata. In addition, the inner structure of the traditional diamond bit working layer is single, namely, the diamond inside the tire body and the tire body components are uniformly distributed in the working layer, the adaptability of the drill head to the rock stratum is not ideal, the service performance of the drill head is greatly reduced, the ordering of the diamond in the diamond tool is a hot research topic in recent years, the ordered diamond tool can enable each diamond in the tool to be fully utilized, the diamond amount of the tool is reduced, and the cost is reduced. However, since it is difficult to manufacture an orderly arrangement template having high-density holes, the orderly arrangement technique is more suitable for being applied to the manufacture of low-concentration diamond tools. Therefore, the orderly arrangement technology is often applied to low-concentration diamond tools such as diamond saw blades, diamond grinding wheels and the like. In order to ensure the service life of the drill bit, the diamond concentration of the traditional diamond-impregnated drill bit is about 90%, the diamond-impregnated diamond drill bit even reaches 120%, and is about 2-4 times of the diamond saw blade, through retrieval, the application publication number is CN102390088A discloses a diamond orderly-arranged tool bit and a manufacturing method thereof, the tool bit comprises a tool bit matrix and diamond particles, a plurality of orderly-arranged accommodating holes penetrating through the tool bit matrix are formed in the tool bit matrix, and the diamond particles are filled in the accommodating holes of the tool bit matrix.
