Wireline Natural Diamond Surface Set Core Drilling B N H P Bits

 

This type of bit is primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bit. It is also recommended for use in drilling harder formations where the available rotary speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations.

 

In most cases, surface set diamond bits will provide higher rates of penetration than in softer formations due largely to the greater degree of exposure of the individual diamond crystals.

To choose a right surface set for the formations drilled, we need at least consider the following aspects: diamond size, diamond grade, profile design.
 

Principle of choosing diamond size--the harder the rocks, the smaller the diamond size should be.

 

Diamond Size Formation Drilled
10/20 SPC* Soft formation
20/30 SPC soft to medium formation
30/40 SPC medium formation
40/60 SPC Medium to hard formation
< 60/80 SPC Very hard formation

*SPC is short for Stone per Carat

**40/60 is standard diamond size for natural diamond core bit

***Other sizes are available as per request
