Shale shakers are components drilling mud cleaning which used for purification of drilling mud fluid of particles cuttings well drilling. Shale shaker is the first stage of the process, purifies solution from 10 – 20% larger than the sludge 75-100 microns. Shale shakers are involved in the large part of the mud cleaning from cuttings, this most widespread means of purification of drilling mud fluid, so they should be given special attention.
This article presents the shale shakers classification according to the type of screens set, the type of oscillations and the number of cleaning levels.
In the process of shale shakers operation, like in case with any other equipment, failures occur. Failures caused by shale shaker work in quite difficult conditions: the cleaning solution contains many impurities that contribute to corrosion of metal, abrasive particles in solution, lead to hydroabrasive wear mesh, negative impact on the shale shaker has a vibration. An analysis of possible shale shakers failures has been conducted, on the basis of which the classification of failures has been developed.
The main directions for shale shakers improvement have been considered: the transition from flexible stretching screen cassetts to framed screen cassettes, general using of shale shakers as a part of mud cleaners and the improvement of mud cleaning efficiency by changing the type and frequency of oscillations.
