Roller cone bit design goals
Roller-cone bit design goals expect the bit to do the following:
Function at a low cost per foot drilled.
Have a long downhole life that minimizes requirements for tripping.
Provide stable and vibration-free operation at the intended rotational speed and weight on bit (WOB).
Cut gauge accurately throughout the life of the bit.
To achieve these goals, bit designers consider several factors. Among these are:
The formation and drilling environment.
Expected rotary speed.
Expected weight on bit (WOB).
Anticipated wear rates from abrasion and impact.
Design focal points include:
The bit body
Metallurgical, tribological, and hydraulic considerations in engineering bit design solutions. (Tribology is a science that deals with the design, friction, wear, and lubrication of interacting surfaces in relative motion.)
