The development of China PDC bit for oil drilling

图片
China began to introduce PDC bits since the early 1980s. After the 1990s, major oil fields began to use PDC bits and achieved good results. Although PDC bits have many advantages and are widely used, the hydraulic problems of PDC bits are even more pronounced than other bits: On the one hand, PDC bits break the rock in a shear manner, and the drilling speed is fast. A large amount of cuttings needs to be removed in time; On the one hand, the temperature Sensitive PDC cutters require rapid cooling. If the clear rock and cooling effect are insufficient, it will not only cause bits of mud, repeated cutting, resulting in a sharp decline in the penetration rate, but also will make the PDC cutting teeth rapidly wear out in the bottom of the high temperature environment, which will seriously affect the use of PDC bit life. Therefore, research and improvement of the effect of PDC bit bottom hydraulics has always been one of the most concerned issues for PDC bit researchers and users. ...
