Operation of Linar motion shale shaker for oil and gas drilling industry2017-01-03
Shale shakers remove large solids (typically larger than 75 microns) from drilling fluid. (Drilling fluid is also known as drilling mud due to its turbid appearance.) Drilling fluids lubricate and cool the drill bit and are therefore integral to any drilling process. Because fluids are expensive to produce, shale shakers improve a rig's economy by stripping away cuttings for disposal before recycling the fluid.
Shale shakers are important components integral to the drilling process and represent the first phase of solids control in drilling industries such as coal cleaning, mining, and oil and gas production. They are often considered one of the most important pieces of equipment in the solids control system, as the efficiency and performance of all subsequent components depends on the cleanliness of the treated drilling fluid.
Linear motion shale shakers represent the newest shaker technology and are the most common approach to solids control in the oil and gas drilling industries. DC Solid control produce linear motion via a pair of eccentric shafts rotating
Shale shaker utilize a motor to generate vibrations. Acting as a sieve, the vibrating action pushes the drilling mud through a wire cloth screen. Drilling mud that filters through the shaker screen is moved into a mud tank for additional processing if necessary. Larger solids pass over the screen surface and are discharged for later collection and disposal.
