Matrix body PDC bitsare 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 bitsare 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.
* Other types and sizes could be designed and manufactured according to the specific requirments.
