Drilling fluids management system is a integration of different drilling fluids purification equipments like shale shakers,hydrocyclones,centrifuges etc.

Drilling fluids management system

Drilling fluids management system

GN Solids Control is 1 of about 10 China manufacturers who can design and manufacture all the equipments for a complete drilling fluids management system

All the drilling fluids management equipments are mounted over the drilling mud tank.

There are many ways to configure your mud tanks below your drilling fluids management equipment. The most common practice requires three sections. Under your shale shaker you have the first section known as the sand trap where the mud to be pumped from this section goes through your Desander. This cleaned mud is then dumped into the second section known as a silt tank. The mud is picked up then pumped through your Desilters. The Desilters dumps the cleaned mud into the third section, know as the clean mud or mixing tank. This will be picked up by  the pump to be pumped back into your bore hole.

To provivide Combination Desanders/Desilters are common when the volume being pumped is under 500 GPM. The tank separation in this drilling fluids managemet application can be achieved with two sections in the mud tank. A clean section where mud to be mixed and pumped down hole is located. The second section is under the shale shaker where the contaminated mud is picked up and processed by the Desander/Desilter combination.

The drilling fluids management Equipments

The first line of defense for a properly designed drilling fluids management system has been and will continue to be, the shale shaker. Without proper screening of the drilling fluid during this initial removal step, reduced efficiency and effectiveness of all downstream drilling fluids management in the system is assured. The downstream hydrocyclones will simply be overloaded beyond their designed capacity.

Hydrocyclones are simple mechanical devices, with out moving parts, designed to speed up the settling process. Feed pressure is transformed into centrifugal force inside the cyclone or cone to accelerate particle settling in accordance with Stoke’s Law #1. In essence, a cyclone is a miniature settling pit which alloys very rapid settling of solids under controlled conditions.Hydrocyclones have become important in drilling fluids management system because of their ability to efficiently remove particles smaller than the finest mesh screens.

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.

Other drilling fluids management equipments includes:centrifugal pump,drilling fluids degasser,etc.

Definition of centrifugal pump
Machine for moving fluid by spinning it using a rotating impeller in a casing with a central inlet and a tangential

Note of Centrifugal pump:

NOTE The path of the fluid is an increasing spiral from the inlet at the centre to the outlet, tangent to the impeller annulus.
In the annular space between the impeller vane tips and the casing wall, the fluid velocity is roughly the same as that of
the impeller vane tips. Useful work is produced by the pump when some of the spinning fluid flows out of the casing
tangential outlet into the pipe system. Power from the motor is used to accelerate the fluid entering the inlet up to the
speed of the fluid in the annulus. Some of the motor power is expended as friction of the fluid in the casing and impeller.

These centifugal pumps are developed and fabricated  as supporting pumps based on requirement of transferring oil & gas drilling fluid. Centrifugal pump adopt the axial sucking structure and all the hydraulic components are wear proof cast iron, which is suitable for delivering the corrosive liquids with suspended particles in well drilling. Its quality is accepted by Weatherford and assembling dimension is same to Mission centrifugal pump.

SB centrifugal pumps are characteristic of abrasion resistance, smooth and stable running, reliable sealing, long service life and convenient maintenance.  Those pumps have been used for land and offshore drilling platforms in more than 20 countries over the world.

Clockwise pumps and anti-clockwise pumps are available.

Mechanical seal and compound seal are available. The compound seal adopts auxiliary impeller, special oil seal and packing seal. Main seal of mechanical  seal is mechanical seal with a long service life, auxiliary seal of machine seal is packing seal to prevent occurrence of accidents.
Shaft seals are lubricated with grease and bearings are lubricated with machine oil and grease  Since bearing covers at two ends of bearings are equipped with grease injectors.

Both inlet flanges and outlet flanges for centrifugal pump are with two series standard dimensions.

Centrifugal pump are widely used in oilfield drilling equipments and drilling mud equipments like shale shakers,desanders desilters etc.Top China  Centrifugal Pump company for drilling mud,welcome to consult us for centrifugal pump for oilfield drilling projects.We supply centrifugal pump worldwide.

Industrial decanter centrifuges are wildely used In oilfield drilling fluids solids control systems.It is used after the mud cleaner or desander desilter for seprating drilling cuttings.We are A China based oilfield industrial decanter centrifuge manufacturer.

How Does An Oilfield Industrial decanter Centrifuge Work?

A decanter centrifuge works by spinning a vessel containing the material to be separated at high speed. It is very much like the rides at the fairground that rotate. You have to lean towards the center to overcome the force caused by the rotation. In fact, some rides are designed specifically to press your body against a back support. The decanter centrifuge spins at very high speeds and pushes the ‘heavy phase’, usually the solids, to the outside of the vessel, just as you would see in the clear flask standing on the bench top.

What Is The Oilfield decanter Centrifuge Process?

In the drilling mud purification system,If you take a sample of the liquid / solid mixture in a clear flask and you observe that there is a separation of the two phases with time, the separation is caused by the force of gravity. The oilfield decanter centrifuge process speeds up the process by increasing the force of gravity 1000 to 4000 times, depending on the solids control equipment. The result is that a process that can take 1-12 hours in a flask is achieved in seconds using centrifugation.,

By the way,we also manufacturer shale shaker

For separating solids from liquid ,Basicly ,processes used for the separation of suspended solids from a liquid media:

  • Sedimentation
  • Filtration
  • Centrifugation

Sedimentation Equipments(Silting mud tank), allows solid particles, which are heavier than the liquid media, to separate and sink to the bottom of a container under the influence of gravity.In drilling mud solids and fluids separation,we usually use silting tank bogether with need equipments to separate solids from drilling fluids.

Filtration equipments( Shale Shaker) incorporates the use of a filter media by virtue of its degree of porosity and regulates what may pass through it. Since the filter media collects suspended solids, the material progressively builds up and will eventually impair performance and require removal, cleaning, and / or replacement.In the solids control system,there are three equipments use this way,Shale shaker,mud cleaner,and the desilter desander.

Multiply the power of gravitational force by more than 2,000 times.

Centrifugation Equipments (Decanter centrifuge) is a highly accelerated form of sedimentation. This rapid form of sedimentation is attained by introducing centrifugal force to the liquid / solid media generating a force that can be over 2.000 times more powerful than gravity itself. This method is fast and eliminates the need for filter media. GN decanter Centrifuge’s complete range of liquid / solid separating centrifuges are designed to separate suspended solids heavier than the liquid media without the use of consumable filter media.

We are a China manufacturer of Liquid  Solid Separation Equipments

Oilfield drilling Poor boy degasser that removes air or gases (methane, H2S, CO2 and others) from drilling liquids. There are two generic types that work by both expanding the size of the gas bubbles entrained in the mud (by pulling a vacuum on the mud) and by increasing the surface area available to the mud so that bubbles escape (through the use of various cascading baffle plates). If the gas content in the mud is high, a mud gas separator or “poor boy degasser” is used, because it has a higher capacity than standard degassers and routes the evolved gases away from the rig to a flaring area complete with an ignition source.

State International Engineering can design and manufacture mud gas separators, either as standalone units or supplied with choke and kill manifolds.It is used before shale shakers.

Based upon your predicted operating conditions and your required gas handling capacity we will be able to calculate the optimal size of your mud gas separator. All our mud gas separators are supplied with a complete calculation package; this will include mechanical strength calculations, theoretical separation capacities and safe working pressures etc.

All State’s poor boy degassers are fabricated to ASME VIII div 1 or PD 5500. The vessels are then hydrostatically tested with a 3rd party classification society witness. Our mud gas separators are supplied with a product certificate and design review.

Poor boy degasser

Poor boy degasser

State International Engineering poor boy degasser are supplied with top quality temperature and pressure sensing equipment where requested. These instruments can provide local displays at the separator, a display at the choke and kill control system and give repeated signals for the drilling control system. State can also provide loop seal pressure monitors and alarms. All this can be achieved through an State Int. Eng. hazardous area certified, control system.

Oilfield drilling Poor Boy degasser is professional equipment to treat the gas invade mud. When the drilling mud result gas invade, the proportion of its weight and viscosity have a greater deviation not to meet the requirements of drilling. The serious situation is that would cause Chung well, and even blowout accident occurred, if not to treat it timely. ZYQ series Gas-liquid Separator combined with the (Company site: Solids Control System

Electric Ignition Device can be used to ensure the drilling process smooth. It is devided into the normal pressure gas-liquid separator and pressure auto-control gas-liquid separator, according to the pressure.Ga-Liquid Separator is your best choice to prevent drilling fluids invasion.
