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.

How does a PDC bit work?

Everyone in the work and study, there will be a process, learning and work are also methods, so people in the daily life of the product will have its own working principle, PDC bit is the same, let's see how it works. The PDC bit is mainly based on the cutting teeth installed on the body of the bit. However, these cutting teeth also have two kinds of structure, which are the composite cutting teeth and the tooth column. The diamond composite cutting teeth are mainly formed by welding the composite sheets directly into the reserved grooves above the drill body, so it is usually used in the carcass bit. The tooth column cutting teeth are mainly welded to the tungsten carbide column, which will be embedded in the tooth column or in the teeth that are welded on the body of the bit. It is usually used in the steel bit, and some of them are used in the PDC bit of the matrix. DIAMONDWK is a highly professional manufacturer in PCD & PDC field. Our main products are P
