What does a effective drilling fluids solids control system include ?

Effective solids control can be attributed to the overall performance of all the components of the mud systems. Conditioning the drilling fluid with the goal of dramatically lowering maintenance cost, avoiding excessive chemical treatment and maintaining drilling mud systems volume will decrease the chance of equipment failure, unnecessary high mud costs, hole and drilling problems.
In the early oil industry open earthen pits were used as settling area to separate solids and mud thereby acting as a solids control equipment. Now, with the stringent environmental regulations and high mud costs, the economics of an effective mud system come into consideration. Different solids control companies introduce zero-discharge systems, closed-loop systems,"quick move" technology, screening technology, disposal options etc.
We use the below solids control equipments in drilling fluids purification usually,they are combined to a system called solids control system,and we usually have 5 stages to applied to the system,what are the functions of the 5 stages equipments in drilling ?Let’s see together!

Shale shaker: The shale shaker is the first stage of solids control equipment in drilling purification system. It can remove cuttings above 75μm brought from the drilling well to leave the liquid with smaller particles into the tanks below, which will flow into next grade solids control equipment to be treated.
Vacuum Degasser:Gases are entrained in drilling fluids from the wellbore during normal drilling operation as well as during “kick” or well control situations ,these gases may bring safety hazards and create operational problems, in case of the presence of hazardous gases, it is desirable to localize the point where gas is released from the mud by installing a vacuum degasser.
Desander: Desander is the second stage of solids control equipment.It is mainly used to take away the solids with diameter ranging from 45 to 74 μm from the formerly treated fluids and then send them to the next stage for more purification.
Desilter: Desilter is the third stage of solids control equipment.In this case,the solids with diameter ranging from 15 to 44 μm are to be separated from the rest,which will go through further processing.
Mud cleaner: Mud cleaner is the second or third stage separation equipment of drilling liquid, which will deal with the mud after being treated by the first grade separation equipment.
Decanter centrifuge: Decanting centrifuge is used in separating suspension of solid phase with particle diameter d≥2μm for drilling mud and fluids handling.

How drilling mud cleaner works in oilfield ?

The KOSUN mud cleaner is suitable for the fluid and also strong handle program concerning the oil gas drilling, it is primarily used for removing the solid particles which happens to be sieved by the separation and also vibration screen in the drilling fluid.
In most drilling operations, a drilling mud cleaner is installed in its mud tanks. It is usually located in a mud tank in the same location as with the desilters. the application of mud cleaner The application of the mud cleaner is to remove drilled solids larger than barite. Solids smaller than 74 micrometers can be removed by the mud cleaner before the viscosity builds up. Mud cleaner can effectively control weighted drilling fluid solid content.

How mud cleaner works ?
The feed slurry of solids and liquid is fed through the inlet at a high velocity obtained by steady pressure of twenty-five .The high velocity transmitted to the feed section creates a spinning velocity and resulting centrifugal forces.The vortex finder causes the stream to spiral downward towards the hydro cyclone wall,in a downward spiraling stream.
The solids separate according to size and weight particles.In the destiny range of particles in drilling fluids ,size is of far more influence than the variations in density so that basically the biggest particles settle first and fastest.
The cone section narrows ,inner layer of the downward spaining liquid turn back toward the overflow because of the increasing centrifugal forces near the center.

How to maintain the drilling mud decanter centrifuge ?

KOSUN decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system.oilfield Decanting Centrifuge are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.
How can we maintain the drilling mud decanter centrifuge to keep its high capacity and serve oilfield solids control system better? The following will give you the answers.

1. Minimize the need for gears or belts to drive the centrifuge.
2. Control and maintain speed during the decanting process.
3. Develop high torque at very low speeds.
4. Two motor applications, one for the bowl and one for the scroll.
5. The bowl has a very high-reflected inertia.
6. The scroll is usually in continuous regeneration, as it runs at a slower speed than the bowl and is pulled along.
7. Torque limiting on the scroll is very important.
8. Some configurations require zero-speed operation of the scroll ( differential gearbox ).
9. Dynamic braking or regenerative modules may be required if the bowl is NOT driven by a drive.
10. Explosion-proof environments.
KOSUN drilling mud decanter centrifuge is built around a slender cylindrical bowl with a relatively large length/diameter ratio and a conical end. This bowl rotates at speeds of up to 4000 rpm (according to model), producing centrifugal force of anywhere from 300 to 3130 G. The other key components include a main drive motor, heavy-duty gearbox, back drive motor and control panel.

Defference on vacuum degasser and poor boy degasser fluid processing

Vacuum degasser gas cut drilling fluid is used to remove the gas, its capacity should be able to reach full flow processing. Vacuum degasser must be placed after the drilling fluid shale shaker sand pump drilling fluid prior to treatment. Because drilling fluids containing gas, drilling centrifugal sand pump cavitation will occur, not only drilling sand pump cavitation performance degradation, noise and vibration, shortened life expectancy, serious cause fluid sand pump is not working or damaged.
Gases are entrained in drilling fluids from the wellbore during normal drilling operation as well as during “kick” or well control situations ,these gases may bring safety hazards and create operational problems, in case of the presence of hazardous gases, it is desirable to localize the point where gas is released from the mud by installing a drilling fluid degasser.

Vacuum degasser is a special-purpose solids control equipment and a new type one for the drilling fluids system. It can get rid of various gas of invasive drilling quickly. Drilling mud vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Also, at the same time vacuum degassing machine can be used as a heavy-power agitator and supported applicable to all types of drilling mud purification system. The drilling vacuum degassing unit design of the structure is scientific and rational. So we are able to achieve an effective gas-liquid separation, filter out impurities and to ensure that the exhaust pipe is always smooth.
Defference on vacuum degasser and poor boy degasser fluid processing
Vacuum degasser usually used to separate less gas than poor boy degasser. Although they both are degassing devices. Poor boy degasser is set up before shale shaker in the oil and gas well drilling. Before fluid flowing to shale shaker it need to be processed by poor boy degasser for safety working condition. Especially when the well depth is more than 4KM.
