A oilfield drilling shale shaker is a device that removes undesirable solids from a drilling mud. Drill bit cuttings and pieces of formation that have brought into the wellbore (or called “drilling solids) and brought out to the surface by the drilling fluid. The fluid flows across a shale shaker before entering the mud tanks to be treated. Most drilling shale shakers install a vibrating motion to a weir or plastic mesh screen. This motion allows the drilling mud to pass through the screen and remove solid lager than the openings in the screen. The shale shaker is the primary and the first stage drilling solid removal equipment in solid control system and usually combined with other solid control equipment.

Sieve Paste and sieve mesh blocking phenomenon since the effective flow area decreases, the shale shaker amount of processing will decrease, easily lead to the loss of drilling fluid . Further, when processing the high viscosity fluid , and shale shaker screen(wire mesh)easily sticky drilling fluid , the mesh size becomes smaller , or completely paste, a phenomenon known sieve paste. Since the mesh size decreases, can be isolated more small particles. For example , our 40 * 40 mesh sieve , sieve paste is not separable out particles larger than 440um . Sieve paste , you may separate the particles larger than 220um . Shale shaker working , the threshold may be wedged between the mesh particles clogging the above , a phenomenon known as blocking sieve .
 

In addition to cuttings and clay paste causing sieve paste and sieve block , the drilling fluid remaining in the sieve dried up , the drilling fluid soluble minerals ( such as salt , anhydrite , some carbonate ) will precipitate and sticky on the wire , also make smaller mesh , or even blocked . In addition , the drilling fluid oils ( eg threaded oil) in the sieve will be sticky .

When the sieve paste and sieve blocking , it shall promptly spray wash or replace sieve. Especially in the shaker is stopped working before , while the vibration, while water ( or jet ), not only help clean the screen surface , to maintain smooth mesh , while also removing the drilling fluid paste, but also reduce the screen load.
