1.Introduction
1 material: cabide
2 suitable for very soft with low compressive strength,such as clay, soft marl,unconsolidated standstone,etc.
3 Cutting structure: the durability of premium diamond insert is improved with new formulas and new techniques for insert bit.
4 Guage structure: Multiple guage protethion with trimmers on the heel of cine,tungsten carbide inserts and hard facing on the shirttal increases guage holding capability and bearing life.
5 Seal and lubracation: Premium O-ring,optimal.Seal compression and curred seal structure can enhance the seal performance.The compensator system and advanced grease can greatly increase the lubricaing reliability.
6 Bearing structure: High precision bearing surface inlaid with friction-reducing alloy and the silver-plated.Abrasion insistance and the silver-plated.Abrasion insistance and seizure resistance of the bearing are improved.
7 Production application: it can receive high WOB in the conventional drilling.It is suitable for various formation by cutting structure with different tooth shape,tooth density and tooth exposure hight.
From 1.8 inch (45mm) to 26 inches (660mm)Note: sizes and types that are not shown above can be customized according to specific drilling requirements
2.The main structure features:
This series inserted bits adopts non-isometry teeth placement in combination with optimized teeth height and shape.
Applying the world's latest sealing technology- metal face sealing ensures the bearing sealing is more efficient,and more suitable for drilling at high rotary speed and high temperature working condition.
New material is applied on the part of gage protection,and reducing the friction from back of leg to well wall,improving quality of the well wall, protecting the back of the leg and seal.
Bit;s bear is enhanced treatment, and prolonging the bit working life, reducing the drilling cost.
3.IADC CODE
1.IADC 437 : Soft formation TCI tricone bits
The 437 tci bits are used to drill low compressive strength, very soft formations. Tci bits maximize the use of bothconical and chisel tungsten carbide inserts of large diameters and high projection.This cutting structure design, combined with maximum cone offset,results in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formation.
Very soft with low compressive strength, such as soft marl,salt,unconsolidated sandstone,soft limestone, etc
2.IADC 517: Medium formation tci tricone bits
The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows.This design provides a fast drilling rate and add cutting structure durability in medium to medium hard formations.
Soft with low compressive strength,such as shale,sandstone,anhydrite,shale,etc.
3.IADC 537: Medium formation tci tricone bits
Medium soft with low compressive strength,such as Shale,sandstone,anhydrite,shale,etc.
4.IADC 617: MEDIUM -HARD formation tci tricone bits
The 617 features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows.This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations.
5.IADC 637: Hard formation tci tricone bits
The 637 bits can be used to drill hard and abrasive formations. Water-resistant tungsten carbide inserts are used in the outer rows to prevent loss of the bit gauge. Maximum numbers of hemispherical-shaped inserts are used in all rows to provide cutter durability and long life.
