Detailed Photos

1.REVERSE CIRCULATION CORING BIT

The bit adopts six-blade channel layout, reverse circulation mode, real-time sampling, sampling and drilling at the same time to reduce the number of trips, real-time observation of formation characteristics to reduce losses and improve drilling efficiency.
 

2.PDC CORE BIT M332
 

1.Circular-arc shaped crown design, placed with high quality cutters, significantly enhances drilling footage capability of the bit.                          2.Inner and out gauges are protected by natural diamond, which helps several-fold increasing wear resistance and stability of the bit.
3.Specially designed core head provides  high rates of core recovery.
4.Optimized waterway design, benefits for the bit cleaning and cooling.
5.Suitable for coring in soft to medium hard abrasive formation, such as soft shale,limestone,sandstone,etc

3.DIAMOND CORE BIT M722

1.Short parabolic configuration outer cone crown design, placed high density diamond particles, ensure efficient reaming and drilling while extending the application and performance rang of casing running operation.
2.Inner and outer gauges are protected by natural diamond, which helps several-fold increasing wear resistance and stability of the bit.
3.Provides high rates of core recovery in medium to medium hard abrasive formation. Such as limestone, dolomite and sandstone, etc.

4.POLYCRYSTALLINE CORE BIT M723

 

1.Short parabolic configuration outer cone crown design, placed high density polycrystalline diamond, significantly increases the stability and life of the bit.
2.Inner and outer gauges are protected by natural diamond, which helps several-fold increasing wear resistance and stability of the bit.
3.Optimized waterway design, benefits for the bit cleaning and cooling.
4.Provides high rates of core recovery in soft to  medium hard abrasive formation. Such as soft shale, limestone, dolomite and sandstone, etc.
