FAQ:
Q1: What is the purpose of drilling mud or fluid?
A: Drilling fluid circulates down the hollow drilling rods and back up the outside of the drill string and hole. Its purposes are to lubricate the bit, remove cuttings from the bottom of the hole, suspend cuttings if needed, control downhole pressure, and cool/ lubricate the drill bit.
Q2: What types of drilling fluid are commonly used?
A: Common drilling fluid types include: water-based mud, oil-based mud, synthetic-based mud, foam, air/foam, and mist/foam. The type used depends on factors like geology, environment, well conditions etc. Water-based is most common.
Q3: What is the purpose of mud motor or turbine?
A: A positive displacement mud motor or turbine attached below the drill bit uses the flow of drilling mud to rotate only the bit, while the drill string above remains stationary. This allows for directional or horizontal drilling techniques.
Q4: What are the advantages of using mud motors?
A: Benefits of mud motors include: ability to steer the bit, drill bend sections and curves, provide more weight on bit than rotation alone, separate drill string rotation from bit rotation allowing flexible reaming or underreaming.
Q5: What determines the drill string design?
A: Key factors that determine drill string design include: formation lithology, well geometry, required depth, drilling method, borehole conditions, drilling fluid properties, hole size, penetration rate needed, equipment limitations etc. Proper design is critical.
