Several Unmissable Points on Desander Maintenance

In oilfield drilling solids control equipment, the desander play a mainly role, it is make as the second stage in the drilling solids control eqipment. So it is necessary to be well maintained all the time.

Here are several points on desander’s daily maintenance:

1. Spare filter element and adequate O-shape sealing ring should be fully prepared.

2. Indicated value displayed on pressure differential gauge should not surpass 3MPa when it is working.

3. Six-hourly examination of wall thickness should be carried out on key parts of desander.

4. The butter from screw thread should be prevented from blocking desander filter element. If blocked, it should be moved from machine and cleaned by high-pressure steam.

5. The moment the filter element is moved from machine, it should be cleaned by water at once to avoid precipitation of sand or support agent at essential points.

6. Only one hydrocyclone is rolling while the other one is saved for later use.

7. No butter should be applied insider its hydrocyclones and seal groove cavity on the top since they are sealed by metal which will be damaged by the potential particle content or fixture from butter.

8. Visual inspection should be conducted into its hydrocyclones.

9. A sudden fall of pressure differential indicates damaged filter element. In this case, one hydrocyclone should be shut and another one started.

10. Filter element should be taken out and examined after one day finishes.

Here are also several unmissed points on drilling fluids desander’s daily maintenance: No butter should be applied insider its hydrocyclones and seal groove cavity on the top since they are sealed by metal which will be damaged by the potential particle content or fixture from butter. Spare filter element and adequate O-shape sealing ring should be fully prepared.
