Determine 2 reveals a desander. The large discharge from The underside in the device is discarded although the cleaned mud leaves from the best from the cyclone which is discharged into the next tank
decantador en la industria del petróleo y el gasoline Un decantador es un dispositivo centrífugo para eliminar partículas muy finas o sedimentos del fluido de perforación para mantener la cantidad de sólidos en el fluido en el punto más bajo posible.
After desilter, the great solids Management equipment is referred to as decanter centrifuge which may Regulate solids of two-5 microns.The real key solids Manage devices would be the shale shaker and decanter centrifuge, which plays a vital Section of the solids Regulate procedure.
Discharge through the desander is built in to the tank immediately downstream. Suction and discharge tanks are equalized via valves or an opening located on The underside of every tank.
As the centrifugal pump is faster in comparison to the rig pumps there will always be a circulation of mud within the discharge pit in to the suction pit. In this manner one hundred% of the movement will be addressed. This technique is proven in Determine 6
The dispersed particles go downward in a spiral path into as underflow although the cleaner and lighter density liquid mud travels up by way of a vortex in the middle from the hydrocyclone, exiting via piping at the very best with the hydrocyclone. Desilter cones are four-six inche diameter to get rid of fantastic sands and silt particles down to twenty micron. Hydrocyclones are made of polyurethane because of its put on resistance and fewer weight than metal.
Use of desanders is mostly discontinued just after barite and/or high priced polymers are additional into the drilling mud, due to the fact a desander discards this kind of large proportion of those resources.
Ensure that operational personnel are well trained to deal with the equipment. Comprehension operational principles, troubleshooting normal processes, and basic safety steps should help in acquiring productive separation and extending products life.
Mud cleaners are quite inefficient and the need for their use continues to be changed by the arrival of linear movement shakers (Check out also: Shale Shaker Layout & Functionality) coupled with using centrifuges.
El cable fulfilledálico que se pasa a través de ellos se vuelve a enhebrar (o “enhebrar�? a los bloques de corona estacionarios ubicados en la parte remarkable de la torre de perforación.
La tolva de lodo es impulsada por una bomba centrífuga que hace fluir el lodo a alta velocidad a través de una boquilla venturi (chorro) debajo de desilter la tolva de forma cónica.

The discharge falls onto a shaker monitor and might be dried, recovering Significantly from the entrained mud. The liquid can possibly be returned on the mainstream or passed by way of a centrifuge if essential. The oil is then saved and the fabric for being disposed of is in dry variety.
Whilst both items of kit are essential, your spending budget will likely Perform a critical part. Desanders commonly cost a lot more due to their greater measurement and higher flow potential.
