Drilling fluid is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes.
As a key part of drilling fluids solids control equipment desander and desilter for separating solids, hydrocyclones in different specifications work against different diameters and for different cleannesses. Besides, separation capacity is closely related with cyclone diameter since larger diameter is aimed at larger particles while smaller one contends with smaller particles.
Operating desander
at peak efficiency is a simple matter, since most desanders are relatively
uncomplicated devices. Here are a few fundamental principles to keep in
mind.
1. Operate the desander unit at the recommended feed manifold pressure,
usually around 30 PSI. A feed pressure too low decreases efficiency and a
pressure too high puts un-due wear & tear on the cyclone.
2. Check desander
cone regularly to ensure the discharge orifice is not plugged.
3. Run the desander continuously let fluid overflow back and process over
& over.
4. Operate the desander with a light spray rather than a rope discharge to
maintain peak efficiency.
5. Maintenance of desanders normally entails no more than checking all cone
parts for excessive wear and flushing out the feed manifold between bores. Large
trash may collect in feed manifold, which could cause cone plugging during
operation. Preventive maintenance minimizes downtime & repairs are simpler
between bores, rather than during drilling operations.
