Characteristics of PDC&Tricone Hybrid Bits
PDC & tricone hybrid bits (Lion Tiger Beast) combine the advantages of both types of drill bits to achieve high efficiency, durability, and versatility, making them particularly suitable for drilling operations in complex formations. This type of drill not only improves rock breaking efficiency and mechanical drilling speed, but also significantly extends its service life and performs well in directional drilling. It is an important tool for modern oil and gas exploration and development, with the following main characteristics:
High rock breaking efficiency
The Lion Tiger Beast drill bit achieves efficient rock breaking capability through the combination of PDC cutting teeth and tricone bits cutting structure. The PDC section adopts a design with large tooth spacing and a medium back inclination angle, which improves the drilling ability of the drill bit, while the tricone bits section further improves the rock breaking efficiency through impact crushing.
Mechanical drilling speed is fast
Hybrid drill bits can significantly improve mechanical drilling speed in sliding drilling, while reducing drill bit torsional vibration and stick slip phenomena, thereby enhancing the stability of the tool face.
Widely applicable
The lion tiger beast drill bit is suitable for complex formations, including tight shale, heterogeneous formations, and hard formations. Its structural design can effectively cope with the alternating soft and hard strata, reducing the problem of drill bit failure caused by geological changes.
Long service life
Due to the high wear resistance and impact resistance of PDC cutting teeth, as well as the low torque characteristics of the tricone section, the service life of Lion Tiger Beast drill bits in hard formations is longer than that of single type drill bits.
Excellent directional drilling performance
When directional drilling in highly inclined sections, the Lion Tiger Beast drill bit can effectively solve the problems of high friction torque, severe pressure support, and unstable tool surface, improving the efficiency of directional drilling.
Reduce wear and maintenance costs
The design of the Lion Tiger Beast drill bit optimizes the arrangement and structure of the cutting teeth, reduces wear, and extends its service life. Meanwhile, its composite structure reduces the frequency of replacement and lowers maintenance costs.
Ability to adapt to complex working conditions
Under high temperature, high pressure, and hard formation conditions, the Lion Tiger Beast drill bit performs well. It combines the efficient cutting ability of PDC bits with the impact crushing ability of tricone bits, enabling it to work stably in harsh environments.
Improve drilling efficiency
Practice has shown that the application of lion tiger beast drill bits in complex formations can significantly improve drilling efficiency and reduce drilling cycles.
