A centrifugal unit for eradicating pretty fantastic particles, or silt, from drilling fluid to keep the quantity of solids during the fluid at the lowest doable stage. Typically the lower the solids content material of mud, the faster is the rate of penetration. The desilter will work on the identical theory to be a desander.
Las actividades de perforación y exploración generan dos tipos de residuos: recortes de perforación y fluidos de perforación usados. La mayoría de los desechos asociados con las actividades de perforación de petróleo y gas representan amenazas significativas para el medio ambiente.
Right after desilter, the high-quality solids Management devices is termed decanter centrifuge that may Management solids of two-5 microns.The main element solids Manage products may be the shale shaker and decanter centrifuge, which performs a vital Component of the solids control system.
The Derrick spherical and inline desilters are meant to clear away silt-sized (twenty to seventy four microns) solids from drilling fluids. Derrick’s spherical desilters are easy to function and simple to keep up. Optional shutoff valves on Each individual spherical desilter cone inlet allow personal cone removing and inspection without interrupting operation of the desilter.

When equally oil and fuel desanders & desilters are managing, the hookup must be as proven in Determine 7. Again, both of those centrifugal pumps really should be one hundred twenty five% of the rig pump level.
The function of desanders is to cut back loading downstream on desilters. Installing a desander forward of your desilter relieves a significant amount of solids loading on the desilter and improves desilter performance. Superior premiums of penetration, particularly in the unconsolidated surface area hole, the place the most important-diameter bits are utilized, ends in creating larger concentrations of drilled solids.
Set the hydrocyclones at the right operational angles as specified from the company. The overall performance of desanders and desilters heavily depends upon the proper angle for effective centrifugal drive generation.
Desanders are set up immediately downstream of the shaker and degasser. Suction is taken from the quick upstream tank, typically the degasser discharge tank.
As well minimal a stress ends in inefficient separation; far too higher a pressure will give an improved separation though the bladders will fail.
Desilter suction is usually taken in the rapid upstream tank, ordinarily the desander discharge tank. Desilter suction and discharge tanks are, once more, equalized by way of a valve, or valves, or a gap Found on The underside of each tank. The size of the valve or opening should be:

The discharge falls on to a shaker monitor and might be dried, recovering much in the entrained mud. The liquid can possibly be returned into the mainstream or passed desilter by way of a centrifuge if vital. The oil is then saved and the fabric to become disposed of is in dry kind.
When dealing with the drilling fluid to remove a selected sizing array one hundred% from the fluid stream has to be processed, for the reason that particles not eradicated The 1st time are circulated again down the hole again. Don't just do they then increase the erosion with the drill string, Bottom Hole Assembly, and open gap, they on their own are subject to abrasion and regrinding underneath the oilfield drilling bit.
