A Desander can be a specialized tools Employed in the oil and gas marketplace for your elimination of solid particles, largely sand, as well as other abrasive resources, from the creation fluids or drilling mud.
Desanders are utilized continually all through drilling surface holes. Plumbing might be organized to system all complete surface area pit quantity after starting a visit.
The position of desanders is to scale back loading downstream on desilters. Installing a desander in advance with the desilter relieves a major level of solids loading around the desilter and increases desilter effectiveness. Large rates of penetration, specifically in the unconsolidated floor hole, where by the biggest-diameter bits are employed, results in making greater concentrations of drilled solids.
The desander has to be protected against the introduction of grease, oils along with other floating components normally which should be keep upstream in order to manage the equipment’s consistent and correct Procedure.
Desanders are principally intended to get rid of sand, but they may properly get rid of other strong particles which include silt, clay, and smaller debris from output fluids.
An oil and fuel desander is fed by a centrifugal pump the pump mud incorporates a capacity not less than 1.twenty five instances the prepared circulating charge (e.g. 1250gpm if circulating around the properly at 1000gpm) . Drilling fluid ought to move from the best of your sand traps into a little suction pit.
Desanders are generally reliable Management products. Cyclonic desander and desilters make use of a centrifugal pressure to individual solids from liquids. There won't be any rotating parts. Centrifugal pressure is made by turning The top of the centrifugal desander pump into a substantial-pace rotating circulation inside of a cone.
Use of desanders is generally not cost-effective with an oil-base drilling fluid as the larger sized cones discharge a significant amount of the liquid section.
Desk two: Hydrocyclone application The scaled-down the diameter from the cyclone, the higher is definitely the working force and also the more compact the particles that can be eliminated.
Figure two shows a desander. The large discharge from The underside of the unit is discarded even though the cleaned mud leaves within the leading on the cyclone and is particularly discharged into the next tank
Servicing for Desanders ordinarily entails standard inspections, cleansing or substitution of worn components, and monitoring of fluid circulation premiums. The precise maintenance needs may well change according to the application and utilization.
A centrifugal pump is used to pump the drilling fluids in the mud tank into the set of hydrocyclones.
