Product Description

Far Eastern Drilling are API (API-7-1 & API Spec Q1) factory specializes in drill bits, such as PDC Bit,Tricone bit,Hybrid Bit,HDD Hole Opener,Foundation Roller Cone Bits and related drilling tools,application fields includes for oil well drilling, gas well drilling, geothermal well drilling, mining, geological survey, hydrographic survey, water well drilling, HDD pipelines installation projects, foundation rock piling projects. 

Polycrystalline diamond compact (PDC) bits deliver premium performance and durability for a wide range of standard drilling applications. According to body material,PDC bit can be divided into Steel body and Matrix body.These matrix- and steel-bodied bits incorporate the latest cutter technology, computational fluid dynamics (CFD), enhanced hydraulics, and various structure geometries to maximize ROP.

Matrix-body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail. For diamond-impregnated bits, only matrix-body construction can be used.

Matrix body PDC bits are primarily used for these applications:

• Soft to medium-hard formations 
• High volume 
• High sand 
• Applications where the same bit will need to be used for several bit runs 

The strength and ductility of steel give steel-bit bodies high resistance to impact loading. Steel bodies are considerably stronger than matrix bodies.A beneficial feature of steel bits is that they can easily be rebuilt a number of times because worn or damaged cutters can be replaced rather easily. This is a particular advantage for operators in low-cost drilling environments.

Steel body PDC bits are primarily used for these applications:

• Drilling in shale formations 
• Soft limestone sites 
• Fast drilling in the stratum 
• Natural gas drilling 
• Deep wells 
• Abrasive formations 

Designed for higher ROP in drilling deep and medium-hard rocks,PDC drill bits always drills from ground to bottom directly without changing another drill bit, it will save huge drilling and laobur cost.
Different from tricone bits, the PDC drill bits need lower WOB but higher RPM,so it always works with mud motor to get high rotating speed.

Quality of PDC drill bits mainly depends on quality of PDC cutters,we provide unique solution according to specific requirement and detailed geological information.
