Dewatering unit

Brightway Dewatering Unit includes a contained automatic flocculation unit with pumps, polymer preparation tank and mixing system. Dewatering system uses coagulant and flocculants chemicals including Poly Aluminum Chloride( PAC) and Poly Electrolyte(Polymer) to coagulate and flocculate the solids in the fluid and make the slurry in a condition that centrifuge can separate the solids from the mixture more convenient. Cuttings generated in the dewatering system are discharged by the centrifuge in the corral; liquid is discharge straight to one of the buffer tanks.

The Dewatering suction lines could be connected to middle mud pit and all ES tanks.

The gathered waste water in the waste pit or the amount of the mud which the mud engineer wants to dump ( usually at the end of drilling sections) should be transferred to the ES tanks or the mud pit and from there could be processed by dewatering system.
The overall objective of dewatering systems is to process drilling waste. Typical applications are:
 Reduction of the liquid waste volume generated
 Recycling back into the active fluids system
 Disposal
 Release in an environmentally safe and cost effective manner.

The main aim is to reduce well costs, either through a reduction in fluid volume used during the well, and /or through a reduction in disposal costs.
Dewatering systems have become major factors towards “closing the loop” in the dry location or zero discharge concept. The displaced or excess drilling mud along with the excess location liquids produced on the dry or zero discharge location are channeled to the collection pit and placed in the storage system. The dewatering system is utilized to process the liquid waste from the active mud and the storage system. The cleaned effluent from the dewatering system can then be :
1) Returned to the active mud system
2) Returned to the drill water tanks for use as dilution
3) Treated further to acceptable regulatory standards for release to the environment

Brightway Centrifugal Pump

What is solids management centrifugal pump detail?
In solids management mud system, there have centrifugal pumps for hydrocyclones. The mud transfer pump for charging centrifuge, the lubricating substance compounding pump for configuration, and/or the cutting pump for shredding lubricating substance, the trip pump, etc. we have a tendency to can also say, there’s horizontal pump, vertical pump, screw pump, etc.

Different equipments request completely different pumps as power resource or mud provides. Meanwhile, {different|totally completely different|completely different} solids system configuration can have different pumps position, design, or types.
Detail pump in field solids management
For solids management equipments, the separated hydrocyclone separators or mud cleaner we have a tendency to should match pump as mud feeding pump. The centirfugal pump transfer lubricating substance to the cyclones body of water line for resultant method.
Usually, these pumps area unit horizontal one. They’ll be mounted on mud tanks ends or below the slant plate of shaker tank. ?When we have a tendency to set pumps below shaker tank can save abundant area. However, then it’ll be inconvenient once we repair or examine pumps.
But generally in solids system there’ll be vertical pump or submersible suspension pump rather than horizontal pumps.
We know in solids system, the lubricating substance appears blood to our physique. where as centrifugal pump are the transfer tools. They pump lubricating substance from here there between completely different lubricating substance tanks or compartments.Let’s see, once mud cleaner or hydrocyclone desilter what pumps there? affirmative, the fourth solids management equipment-Decanter centrifuge. For bottle centrifuge, we’d like pump transfer lubricating substance from desilter compartment to centrifuge input.

Impacts the solid content exerts on drilling mud system

1. Drilling mud system is reciprocally proportional to solid control system.The drilling system will be at in clean water stands at 100%. once the solid content goes up to 7-membered, drilling speed reduces to 5 hundredth, that’s 0.5 that in cleaning water. And lot of as varied information show, once the solid content is not on the so much aspect 7-membered, 100 and twenty fifth down in solid content canbring drilling speed up a minimum of 100%.

  1. In many solid content ranges, the increase rates of drilling mud system. If the solid content remainsunderneath 7%(equal to such density joined.08 g/cm3), drilling speed will climb at the fastest speed; if it goes on the so much aspect 7-membered, it does not build lots of significance to drilling speed.
  2. Drilling speed is influenced, to the most effective extent, by mixture particles below 1µm in diameter. it’sestablished by experiments that mixture particles with diameter below oneµm ar twelve times lots ofauthoritative than the coarse particles with diameter above one cape. consequently, the lots of themixture particle there ar, the slower the drilling speed is.

In a word, if the solids management instrumentality ar place into prompt application, they go totake away such harmful solids as drill cuttings, keep the content of useful solids like barites and bentonites beneath the sway of laws, and, at a similar time, recover barites and bentonites from drilling fluids.

So the solids management instrumentality utilised within the drilling mud system ar essential, like fieldsedimentary rock shaker, drilling fluids cleaner, mud cleaner, decanter centrifuge, desilter, vacuum degasser and completely different devices. They compose a whole field drilling mud solids system, that playsa crucial role among the entire field drilling system.

What is the effect solids control equipment exerts on drilling project 1?

One of the most critical roles of this mud is as a lubricant. Drilling causes tremendous friction, which can damage the drills or the formation being drilled. Drilling mud cuts down on the friction, lowering the heat of drilling and reducing the risk of friction-related complications.

solids control system

The mud also acts as a carrier for the materials being drilled, with material becoming suspended in the mud and then being carried up the drill to the surface.

 

Brightway solids control equipment is the precondition to maintain the excellent drilling mud property which is the premise to prevention of underground accident, protection of oil layer, improvement of drilling rate and reduction of drilling cost.
