A Desander is usually a specialized gear Employed in the oil and gasoline business with the elimination of strong particles, primarily sand, as well as other abrasive products, with the manufacturing fluids or drilling mud.
The parameters that have to be looked on while picking out a desander for the specific application are:
Another excuse for a minimum of three % underflow is usually that, at lower costs, the dimensions of particles that should be eliminated is unfavorably impacted, as an excessive amount good will remain inside the fluid.
When treating the drilling fluid to eliminate a certain measurement assortment 100% from the fluid stream must be processed, because particles not eradicated The very first time are circulated back again down the hole all over again. Not simply do they then raise the erosion in the drill string, Base Gap Assembly, and open gap, they by themselves are matter to abrasion and regrinding under the oilfield drilling little bit.
The discharge falls onto a shaker screen and can be dried, recovering Substantially in the entrained mud. The liquid can possibly be returned for the mainstream or handed through a centrifuge if important. The oil is then saved and the material being disposed of is in dry type.
Desander of easy cycloning: These are very good for sandy or somewhat sandy soils. Following the sludge has handed by way of a screening phase to remove oversize, it can be fed to some cyclone separator.
Desanders are set up promptly downstream of the shaker and degasser. Suction is taken from your rapid upstream tank, ordinarily the degasser discharge tank.
Suction really should not be taken within the tank into which chemicals along with other elements (barite and bentonite) are included because useful treating materials may be shed.
Irregular Procedure as a result of faulty manifolding; each desander cyclone device must have its personal pump and, for example, not be Element of the hopper process; Every single pump needs to be dedicated to only one undertaking.
Desilter cones differ from desander cones only in dimensions and work on the exact same ideas. Frequent desilter cone sizes are concerning two and 5 inches. A centrifugal pump ought to be dedicated to deliver fluid to your desilter manifold only.
Should you’re inside the oil and gas business, chances are you’ve heard about desanders. Irrespective of whether you’re a technological Experienced or new to your marketplace, knowledge how a desander performs and its differing types is crucial. Let’s dive into what desanders are, the categories accessible, their attributes, and how they do the job.
For this reason, hydrocyclones can only be utilized for the desanding and desilting of unweighted drilling fluids. Should the fluid is weighted with barites there will be abnormal lack of beneficial densifying content (Look at also: WBM Chemical substances �?OBM Chemical compounds).
