Why shaker screens are multiple-layer configured

Shaker screens are the filter cloth to separate drilling cuttings and fluids during oil and gas drilling.

As we know, the shaker screens consisted of S.S wire mesh, plastic lining (Optional), back support, sealing, handle (optional). The screens configuration including followings

  1. Screen cloth selection-1~4 layers

Why do we need multiple-layers mesh?

The supporting layer is the base of screen. It is woven by coarse wire with large opening. It can support surface screen and won’t affect the conductance or filtration performance. For the middle layer, it can help get the accurate cut point as per D100 with proper selection

Compared to other layers cloth, the top layer screen on surface is easy to damage since the extra fine diameter and aperture. Multiple-layer mesh screen enhance the strength of screen cloth in deed. And even there is slight damage on screen surface it can be operated continuously.

Screens made by different manufacturers

Multiple-layer shaker screens made by different manufacturers will vary from each other. So there is API number to let screen mesh size be interchangeable and accurate for certain phase drilling mud process

For example, manufacturer A supplied screen sized 100mesh without API number may be in API 80 since the different layers number and mesh size, as well as the diameter. Manufacturer B supplied screen sized API 60 may be equals to MG 80 mesh or even finer.
