Requests of operating oilfield shale shaker

In many different industries, shale shaker is utilized widely, such as coal cleaning plant, mining, petroleum drilling, and natural gas exploitation, etc. And the shakers that are currently used in petroleum drilling were initially introduced from the coal cleaning industry. It can remove the solids that is over 75μm diameter.

oilfield shale shaker

As solids over this diameter is much harmful on the drilling fluids property. They must be removed from the drilling mud at the first stage of solids control system. And shale shaker with API 200 mesh (75μm) is designed and manufactured basing on this principle.

Shale shakers can be divided into linear motion shale shaker and ellipse & round motion shaker, basing on the difference of their screen basket moving tracks. As the most important equipment in solids control system, shale shakers are widely used in almost all kinds of drilling rig, and they take an important part in drilling fluids cost as well as total drilling drilling cost. So it is necessary to choose right type of linear motion shale shaker according to the viscosity of drilling fluids & solids density.

The requests of operating oilfield shale shaker:

1.Adjust the specification of screens with the variation of the lithology, drilling rate, well depth and the type of drilling fluid. Choosing the effective screens with fine mesh as far as possible.
2.The flow area should cover from 75 to 80 percent of the total screen area at the normal drilling rate.
3.The drilling fluids pumped out of wellbore should be treated by drilling fluids shale shaker as the primary purification process, and keep 100 percent utilization of shale shaker.

Shale shakers are the most important and easiest solids removal equipment, which is characteristic by highly cost-effective. However, the next stage solids removal equipment will not perform effectively, if shale shakers are used incorrectly.

As China’s important drilling fluids solids control equipment manufacturer, KOSUN not only manufactures shale shaker, shaker screen, decanter centrifuge,vacuum degasser, desander, desilter, and so forth., but on best of that could provide screens for other shale shakers in line with customers’ specifications.
