desander 1. n. [Drilling] A hydrocyclone machine that eliminates massive drill solids from The entire mud system. The desander should be Found downstream in the shale shakers and degassers, but ahead of the desilters or mud cleaners. A volume of mud is pumped into your vast upper section on the hydrocylone at an angle roughly tangent to its circumference. Given that the mud flows all around and steadily down The within in the cone condition, solids are separated with the liquid by centrifugal forces.
five. The dimensions and quantity of cyclones is usually flexibly configured to higher satisfy consumer customization requirements
It truly is a good idea to Possess a straight pipe before the primary cone which is three times the pipe diameter. This permits time for that solids and liquid to remix evenly
Never ever produce a horizontal bend into an inline hydrocyclone manifold. Centrifugal pressure will pressure solids to the skin of your bend, which could overload some cones and bring about solids to bypass others.
Creating a centrifuge pump to operate numerous parts of equipment is just not a good idea, as doing this necessitates compromises in general performance and possibilities for incorrect Procedure.
Desanders do the job by employing centrifugal drive to different heavier solids (like sand) from the incoming fluid. Because the fluid enters the cyclonic separation unit, it's spun swiftly, triggering the heavier solids to maneuver outward and settle in a set chamber, even though the cleaned fluid carries on its path throughout the outlet.
We also deliver OEM services. We design and style, manufacture, and market Desanders and Desilters in your drilling purposes. If you wish to know most current Desanders and Desilters selling price, don’t be reluctant to Get in touch with us whenever. We can get back again for you in 24 several hours.
The maximum (max) gpm would be the utmost circulation charge expected, not the backflow, as there'll be periods once the unit will not be working and the entire rig movement price will have to go through the valve or opening.
Desanders and desilters are used to get rid of solids from drilling fluid that a shale shaker is incapable of eradicating.
We're maker with prosperous activities of solids-fluid separation. So It is really mean you'd probably spend a lot less Value for a similar equipment and customizing offered.
Because the centrifugal pump is faster as opposed to rig pumps there will almost always be a move of mud from the discharge pit in to the suction pit. In this manner a hundred% from the circulation might be addressed. This system is proven in Figure 6
When dealing with the drilling fluid to remove a certain dimension vary one hundred% from the fluid stream need to be processed, due to the fact particles not removed The 1st time are circulated back down the outlet once more. Don't just do they then improve the erosion from the drill string, Base Hole Assembly, and open up hole, they by themselves are topic to abrasion and regrinding underneath the oilfield drilling bit.
When the liquid reaches the tiny conclusion of your cone, it's pushed out in the tube and proceeds to the subsequent step within the purification approach.
The discharge falls on to a shaker display screen and might be dried, recovering Considerably on the entrained mud. The liquid can both be returned towards the mainstream or passed through a centrifuge if vital. The oil is then saved and the fabric to get disposed of is in dry kind.
The brand new drilling sound control technique will additional improve the combination of good Management gear. We have been using a new style of double-layer or three-layer vibrating display screen to replace the desilter (sand and desilter built-in machine). Beneath the premise of meeting the circulation necessities of various drilling fluids, the website amount of the reliable control process could be compressed.
