Effect of drilling fluids in drilling industry

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.
Drilling mud solids control equipment is used in a drilling operation in which that fluid is circulated or pumped from the surface,down the drilling string through the bit and back to the surface via the annulus, such as shale shaker, decanter centrifuge, mud cleaner, etc. Drilling fluids system satisfy many needs in their capacity to do the following below:
1.suspend cuttings or drilling solids,remove them from the bottom of the hole and the well bore and release them at the surface.
2.control formation pressure and maintain well bore stability.
3.seal permeable formations
4.cool,lubricate and support the drilling assembly
5.transmit hydraulic energy to tools and bits
6.minimize reservoir damage
7.permit adequate formation evaluation
8.control corrosion
9.facilitate cementing and completion
10.minimize impact on the environment
11.inhibit gas hydrate formation

The most critical function that a drilling fluids system performs is to minimize the concentration of cuttings around the drill bit and throughout the well bore. Of course,in so doing,the fluid itself assumes this cuttings burden, and if the cuttings are not removed from the fluid,it very quickly loses its ability to clean the hole and create thick filter cakes. To enable on site recycling and reuse of the drilling fluid, cuttings must be continually efficiently removed.The complete drilling solids control system can effectively remove the solids and particles in drilling fluid.
