DC Solid control Mud cleaners function and common standards

With the combination of a desander and desilter mounted over a powerful multi-functional shale shaker, DC’s line of mud cleaners offer both high performance and versatility for the operator.

Common standard of the mud cleaner:
Explosion and non-explosion proof electrical systems for 50 or 60 hz.
Deck angle adjustable during operation (from –2 ½ to +5 degrees).
Pretensioned screens with wedge fastening and optional hook strap.
High G-Force of 2 – 8.5 G provides dry solids discharge.
Efficient and simplified design: no gearbox, hydraulics, pneumatics, oiling system or belts.
Shaker dimensions and mud inflow level are compatible with most existing mud tank systems.

Mud Cleaners have the capability to process the entire drilling-fluid circulation volume, and remove drilled solids from weighted mud system; retaining expensive barite and liquids, and economically reducing hole problems associated with excessive drilled solids.

Drilling fluid passes through a series of hydrocyclones – either desander or desilter units that separate the fine, line particles from the heavy,coarse particles. Barite passing through the screen and returning to the active system.

DCS Shale shaker Key specification and advantages

Shale shaker is the most important part in drilling fluids processing system,also plays a decisive role in drilling mud system.Shale shaker decides the performance of the whole solids control system. DC provides both linear motion shale shaker and balanced elliptical shale shaker. DC series shale shaker can meet varied needs of the different customers.

Shale Shakers have evolved from small, relatively simple devices capable of running only the coarsest screens to the models of today. Modern, high-performance shale shakers of today are able to use 10 mesh and finer screens at the flow-line in most applications.

Competitive Advantages of DC Desilter

Desilter is the third phase solids control equipment to treat the drilling fluids, and to improve the performance of drilling mud, which can be combined with desander.  The most common cone is 4” or 5” , mainly to separate the solids in 15-47μm out from the drilling fluids.

The desilters is one indispensable device for stabilizing and adjusting the drilling fluid technical parameters, suitable for those drillers as ZJ70, ZJ50 and ZJ40.  And it can be used together with the sealed circulatory system of the drilling fluid.

High speed centrifuges in in actual application

A problem for everyone who uses decanter centrifuges in the oil field is judging the centrifuge’s capacity, particularly in unweighted mud. Unfortunately the general attitude of the industry is to give hydraulic capacity (how much feed a centrifuge can physically swallow) without regard to the quality of performance a centrifuge can give at
its “rated capacity”.

Another questions is the drum speed, why divided into lower speed, middle speed and high speed centrifuges. We should choose the right and reasonable centrifuges models according to the different industries.

High speed centrifuge has costs, not to the driller, but to the centrifuge owner. Suppose the centrifuge is one pound out of balance. If the centrifuge rotates at 900 RPM, the unbalanced load is 276 lbs, and this unbalanced load is carried by the bearings through to the frame. If it sped up too 1800 RPM, the unbalance load goes up to 1,104
lbs. To keep the centrifuge from shaking itself to death or an early bearing failure, higher speeds require better mechanical tolerances. Generally, to maintain these tolerances over a service life of many years, the centrifuge should be made from stainless steel.
