desander 1. n. [Drilling] A hydrocyclone device that eliminates big drill solids from The complete mud process. The desander should be Positioned downstream from the shale shakers and degassers, but prior to the desilters or mud cleaners. A quantity of mud is pumped to the wide upper section with the hydrocylone at an angle roughly tangent to its circumference. Since the mud flows all-around and gradually down The within in the cone condition, solids are divided from the liquid by centrifugal forces.

All 3 tanks should be connected at the bottom by equalizing valve. Fluid must overflow away from the last tank into the rest of the tank program.

It's a smart idea to Have a very straight pipe before the primary cone which is 3 times the pipe diameter. This allows time to the solids and liquid to remix evenly

Suction is taken through the tank straight away upstream of the discharge tank. The number of cones in use should procedure a minimum of 100% but ideally better than a hundred% on the movement level of all fluids getting into the suction tank with the hydrocyclone. A backflow involving the hydrocyclone discharge and suction compartments of at the very least 100 gpm ordinarily makes sure sufficient processing. Estimations according to rig circulation premiums are frequently insufficient In case the plumbing is not really organized correctly.

Desilter suction can also be taken within the immediate upstream tank, usually the desander discharge tank. Desilter suction and discharge tanks are, once more, equalized by way of a valve, or valves, or a gap Situated desander on The underside of each tank. The size of the valve or opening ought to be:

Desanders do the job by using centrifugal force to separate heavier solids (like sand) with the incoming fluid. Since the fluid enters the cyclonic separation device, it really is spun fast, triggering the heavier solids to move outward and settle in a set chamber, when the cleaned fluid carries on its route from the outlet.

Table 2: Hydrocyclone software The smaller the diameter of the cyclone, the upper may be the functioning strain along with the smaller sized the particles which might be eliminated.

It can help to improve the porosity on the pile Basis, cut down the cost of slurry through the development method, and comprehend the recycling of building mud.

These models make the finest particle-dimensions separations of any total-move solids-Regulate equipment—right down to twelve microns of drilled good. The desilter, therefore, is a crucial product for reducing normal particle sizing and decreasing drilled solids.

Desilter is useful for secondary reliable Handle therapy of mud and liquid to generally be dealt with in land and offshore oil and gas drilling/coal mattress methane excavation/non-excavation directional crossing/piling engineering/waste sewage, mud therapy and various projects.

Since they are often installed with the wellhead within the oil and gasoline subject, These are generally known as wellhead desander. Wellhead desanders are made in both of those ASME and API design and style rankings as per necessity.

去除井口或附近的固体（例如压裂砂、支撑剂），可以提供多种优势，包括：

The primary operate of your electronic Handle technique of your desander is to control the operation from the desander, like starting off, halting, functioning position monitoring, fault diagnosis along with other functions in the equipment.

In the event the drill fee is gradual, generating only some hundred lbs . for every hour of drilled solids, the desander might be turned off as well as the desilter used to procedure the whole circulating system.

Solids are concentrated close to the cone wall in proportion to their mass and exit as underflow at The underside with the cone. Clear liquids and fine solids return with the overflow at the top in the cone.
