Shale agitators remove rock particles from drilling fluid, which is vital for the drilling process. The shale shaker is part of a larger mud removal system and uses a vibrating tray lined with a wire mesh screen to remove solids. Choosing the right screen size and corrosion-resistant materials is important. Shale agitators offer benefits such as reusing drilling fluid, reducing costs, and environmentally friendly disposal of contaminated solids.
Shale agitators are a type of industrial equipment used to remove rock particles from drilling fluid. This drilling fluid, or mud, plays a vital role in the drilling process. It washes away rock chips as they are cut by the drill and also helps cool the drill bit to reduce the risk of overheating. The shale agitator is designed to remove these rock chips and other solid materials from the drilling mud so it can be safely reused over and over again. Shale agitators often serve as part of a larger mud removal system, which helps keep drilling mud free of not only solids, but also unwanted gases and other contaminants.
To understand how the shale shaker works, it helps to understand how it relates to other parts of the drilling process. The drilling fluid, composed of water, petroleum and chemicals, collects in a storage pit or drum above the ground. Once drilling begins, this fluid descends through the drill cables and enters the hole through holes in the drill bit mechanism. From here it goes up the sides of the hole, bringing rock particles and other debris to the surface. Once the sludge reaches the surface, it returns to the storage pit for re-use.
In drilling designs with a mud cleaning system in place, this mud flows directly out of the borehole and into the shale agitator. Shale shakers consist of a vibrating tray lined with a wire mesh screen. Rocks and other solid materials remain on top of the screen as liquid passes through. The vibrating action of the screen helps facilitate this process.
The choice of shale agitator screen is critical to the effective removal of solids. The size of the holes on the screen must be adapted to the size of the rock extracted from each hole. It’s also important to choose corrosion-resistant shield materials such as galvanized steel to withstand the extreme conditions at a drilling site. Many designs include multiple shale agitators so the drilling mud has to go through several layers of cleaning and refinement.
A shale agitator offers many benefits to drilling companies. These systems help clean up the drilling fluid so it can be reused over and over again. Without these shakers, debris in the mud could damage the drill and stop operations. Reusing drilling fluid helps conserve limited resources and also reduces costs for drilling equipment. Finally, shale shakers make it easier to capture rocks and other solids that have been contaminated with oil so they can be disposed of in an environmentally friendly manner.
