Function of decantering centrifuge in oil field:

Decanting centrifuge is ideal choices for separating particles in drilling mud. Decanting Centrifuge separate the suspending fluids using  the principle of centrifugal action, the suspending fluids is pushed into the rotor drum through the inlet pipe and the fluid hole of the spiral feeder. Under the influence of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the nud export of the small end of the drum and excreted.

Functions of drilling mud:

Drilling mud is used to control subsurface pressures, lubricate the drill bit, stabilize the well bore, and carry the cuttings to the surface, among other functions.

 

Why solid cutting should be separated from drilling mud:

As the drill bit grinds rocks into drill cuttings, these cuttings become entrained in the mud flow and are carried to the surface. In order to return the mud to the recirculating mud system and to make the solids easier to handle, the solids must be separated from the mud.

 

How to separate solid cutting from drilling mud:

In order to recycle drilling mud, solids control equipments are used, usually 4 stage solids control equipment used.

1)       First stage: Shale shaker

According to rig size, 1 or 2 or 3 sets shale shaker will be used at the first stage solids control separation.

Usually matched with API 60 or API40 shaker screen.

Cutting over 400µm will be separated in this stage.

 

2)       Desander and desilter is used as the second and third stage separation. For better performance, GN recommend to bear a underflow shaker with desander / desilter.

Some clients may choose mud cleaner for these stages. It is a combination of shake shaker, desander and desilter. But more compact with less space.

 

For smaller size rigs (usually, under 750hp), mud treated by shale shaker and mud cleaner can be used for drilling.

 

3)       In some condition, while drilling depth is big, and high standard mud request, decantering centrifuge will be used as forth stage separation. Finer solids can be separated.

4)       For gas cut drilling mud, vacuum degasser, poor boy degasser and ingnition device will be used.

Drilling Waste Management decanter centrifuge also available from GN

Drilling cutting treatment is one major part for the drilling waste management.For drilling waste,the drilling companies need to have the method to treat the solids part and the liquid phase after drilling.

Drilling Cutting Treatment Equipment

Drilling contractor or the waste management companies usually use the Vertical cutting dryer of the HI G cutting dryer for ths solids phase. GN   VERTI-G cuttings dryers are industry standards as is our all-inclusive cuttings re-injection planning, execution and assurance process. GN Solids Control  are the leaders from China for drilling cutting treatment in desorption technologies incorporating efficient processes for reclaiming base oil, minimizing waste and preparing solids for disposal.

The GN Vertical Cutting Dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900RPM with G force up to 420. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation. GN cutting dryer has been done strict balance testing for all major rotary components to minimize vibration & noisy.It is the ideal products for oil based drilling waste management.

About the drilling cutting waste treatment

Most water-based muds (WBMs) are disposed of when the drilling job is finished. In contrast, many oil-based muds (OBMs) and synthetic-based muds (SBMs) cuttings are recycled when possible. Sometimes the physical and chemical properties of the used muds have degraded somewhat, and the cuttings must be processed to rejuvenate the necessary properties. In other cases, the cuttings have been degraded sufficiently that they cannot economically be reused as new muds, and they must be put to a different type of reuse or final fate.You can consult GN Solids about the drilling cutting treament business.

• What Shakers use the Composite material Mongoose shaker screens?

M-I SWACO groundbreaking MONGOOSE PT shale shaker is the only such unit capable of adjusting on-the-fly as solids characteristics change.

MONGOOSE PT gives you the unprecedented ability to change the shaker motion as the characteristics and volume of the cuttings change. The MONGOOSE PT can go from linear to elliptical motion with the simple flip of a switch.

Balanced and Progressive elliptical motion combined with configuration flexibility to suit your needs.

With the new generation MONGOOSE PRO dual-motion shale shaker, M‑I SWACO has combined balanced and progressive elliptical motion technology for a shaker that adapts as
drilling conditions change. As drilling conditions change, the evolutionary MONGOOSE PRO dual-motion shaker can be adjusted “on the fly.” Simply flipping a switch on the control box reconfigures the shaker from balanced to progressive elliptical motion. There is no need to suspend or shut down operations. With the MONGOOSE PRO shaker operating in the gentler progressive elliptical mode, solids encounter reduced G-forces and longer screen residence time. This results in drier solids, improved drilling-fluid recovery, longer screen life and reduced operating costs.

• Features of MI Swaco Mongoose composite material shaker screens

M-I SWACO DURAFLO Composite Screens use a polypropylene frame with an internal reinforcing cage made of high-strength steel. This design increases screen life and fluids-handling capacity to improve solids-control performance. In addition, DURAFLO Composite Screens are lighter than older metal-backed designs.
Longer screen life. The composite frame design provides smaller more numerous panels, evenly distributing mechanical stresses and containing mesh tears when they occur.

Maintains or reduces current screen weight. Our evolutionary DURAFLO composite screen weighs about the same as the original HIFLO screen and significantly less than metal-frame screens.

Easy to repair. The patented SNAP-LOK plug-repair system, available on DURAFLO screens for the NOV Brandt VSM 300 shaker, reduces repair time to less than two minutes. Simply remove the screen from the shaker and snap in a factory-made plug. This system eliminates the need for removing the damaged mesh and requires no cutting, gluing or bonding time.This gives more advantage to the composite material shaker screens for Mongoose shale shaker.
