Drill Bit

This type of drill bit adopts professional software for PDC cutter layoutdesign and mechanical analysis. It uses high-end PDC cutters with high wear resistance and strong impact resistance, featuring a wide range of applicable formations, high drilling efficienc y, long service life, and excellent comprehensive performance. The structure can be adjusted according to different lithologies and requirements.

The PDC (Polycrystalline Diamond Compact) core bit is a highefficiency tool specifically designed for coring operations in oil, gas,and geological exploration. Its primary function is to efficiently andintactly retrieve subsurface rock samples during drilling, providingcrucial data for geological analysis and reservoir evaluation.By optimizing its cutting structure and hydraulic system, the PDC corebit achieves a balance between coring efficiency and core quality.This makes it particularly suitable for continuous coring in mediumto hard formations.

The PDC roller cone composite drill bit is an innovative drilling toolthat combines the advantages of PDC bits and roller cone bits. It is mainlyused for efficient rock breaking in complex formations and directionaldrilling.Its core design lies in overcoming the limitations of traditionalsingle-type bits in complex conditions such as hard formations and gravelbearinginterlayers through structural integration.

The eccentric bit is a specialized tool designed for hole enlargementoperations in oil and gas drilling engineering. Its core feature lies in itseccentric structure, which allows it to expand the wellbore diameter duringdrilling. This capability is crucial for addressing challenges such asformation collapse and difficulties in casing running, thereby enhancingcementing quality and overall drilling efficiency.Common bit sizes range from 3 1/4" to 26".

The PDC twin - diameter bit is mainly characterized by having two drillbody parts with different diameters. It enhances the overall performance ofthe bit through the PDC cutters distributed on each blade. Compared withtraditional PDC bits, the concentric twin - diameter bit can reduce the stressof the rock around the well, thus having the advantage of increasing themechanical drilling rate in hard - to - drill formations. Additionally, this bitcan eliminate the "stick - slip" phenomenon of PDC bits, protect the maincutting structure and shoulder cutters of the bit, and extend the service lifeof the bit.

The refloat bit is used for fishing operations in drilling and downholeoperations in cases, such as broken drill pipes, worn drill bits, damaged casings,stuck drill bits, and stuck drill rods. Common specifications: φ95/132、φ114/127、φ127/145、φ127/165, etc.
