Drilling fluids shaker screen area unit integral to the drilling method and, among alternative functions, serve to lubricate and funky the drilling bit likewise as convey the trained cuttings faraway from the bore hole. These fluids area unit a mix of varied chemicals in an exceedingly} water or oil based mostly resolution and might be very high-priced to form. For each environmental reasons and to cut back the price of drilling operations, drilling mud losses area unit decreased by removal them faraway from the trained cuttings before the cuttings area unit disposed of. this can be done employing a multitude of specialised machines and mud tanks.
Shale shakers screen are a unit the first solids separation tool on a rig. once returning to the surface of the well the used drilling mud flows on to the sedimentary rock shakers wherever it begins to be processed. Once processed by the sedimentary rock shakers the drilling mud is deposited into the mud tanks wherever alternative solid management instrumentality begin to get rid of the finer solids from it. The solids removed by the sedimentary rock shaker area unit discharged out of the discharge port into a separate holding tank wherever they expect additional treatment or disposal.
Shaker screen area unit thought of by most of the drilling trade to be the foremost necessary device within the solid system because the performance of the serial instrumentality directly relates to the cleanliness of the treated drilling mud.

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.

Brightway Drilling Vacuum Degasser

Vacuum degasser, conjointly known as degasser unit.It is associate elementary degassing unit in treating the lubricating substance employed in oil & gas drilling. Vacuum degasser is found initially stage before sedimentary rock shaker within the complete solids system. Its main purpose is to confirm the operation safely in well drilling and sleek the entire method of solids management.

Why would like Vacuum degasser?
Drilling mud invasive by the gas (methane, nature gas amd Carbon dioxide) from the circle house aroud the oil rig can end in kick, even blowout whereas drilling operation attributable to the unbalance of gas pressure. The perform of the wedge degasser is to separate the bubbles with the scale ≥ 3mm.

How Vacuum Degasser Works?
There ar in the main four opening(mud water, footballer port, mud outlet and waste product drain outlet) within the process tan and every one of them ar connected by pipes. The gas cut in lubricating substance is delivered by the feeding pump into the vacuum degasser tank on tangent route through the water pipe. when the collision of a series baffles specially designed and put in within the inner wall of the tank, the exposure of the mud surface is enlarged and therefore the mud flows down in an exceedingly disturbed flow condition. Meanwhile,The mud and gas finished separation. Free gas is target-hunting through the footballer port connected by pipes at the highest of the tank to the safe place, then burned by the flare ignition device. lubricating substance when gas separation can flow into the treating tank for the additional treatment by the next equipements. like sedimentary rock shaker, mud cleaner and bottle centrifuge etc. The waste product within the degasser tank flows from the drain outlet at very cheap of the tank.

Drilling fluids solids control in drilling mud system 1

Drilling mud system, also called as drilling fluids, is a mix liquids used in the process of drilling deep oil or gas wells. The drilling mud is an integral part of the drilling process, serving a number of functions.

solids control system

One of the most critical roles of this drilling 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.

The mud also acts as a carrier for the materials being drilled, with material becoming suspended in the mud tank and then being carried up the drill to the surface. Different muds can all be used for different circumstances. There are water, oil, and gas-based muds which made from true mud mixed with materials like bentonite clays to synthetic drilling fluid.

Due to its high cost, drilling mud system is recirculated throughout the drilling process. As it rises to the surface, it passes through shale shaker that screens the materials from the borehole, before being cycled back into the drilling mud system that delivers mud to the head of the drill bit. This recirculation process, called as drilling fluids solids control, is designed to cut down on waste by reusing as much mud as possible.

Mud Tank System

High quality oilfield mud tank system must be fabricated under professional configuration. The optimal proposal with high efficiency and low cost. Cater to clients’ specific demand and actual drilling conditions.

Actually, we need almost fluid system include shale shaker tank, active, storage tank or mixing tank. Sometimes, there will be also the trip tank, pill tank, and swab or test tank. The mud tanks are different size or dimension. It depends on whole mud tanks system capacity or flow mud pump flow rate. Whole mud system including different phases and process steps. We need to calculate all information in detail.

The Structure of Shale Shaker

Solids control is a technique used in drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally solid control system is consist of five stages, including mud tank, shale shaker, vacuum degasser, desander, desilter, centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as high efficient mud cleaner.

When air enters into the drilling fluids, vacuum degasser is used to separate the air. If no air in the mud, the degasser would work as a big mud agitator. All these equipments are mounted on the top of the mud tank. After separating the solids, the clean mud would be pumped into the borehole again.

 

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.

Shale shakers consist of the following parts:
Hopper – The Hopper, commonly called the “base” serves as both a platform for the shaker and collection pan for the fluid processed by the shaker screens, also known as “underflow”. The hopper can be ordered according to the needs of the drilling fluid, aka “mud” system. It can come in different depths to accommodate larger quantities of drilling fluid as well as have different ports for returning the underflow to the mud system.

Mud Agitator

Brightway mud agitator is a part of solid control system and mud tank, which is mainly used in agitating and blending drilling fluid so as to control the depositions of solid particles in its tankcycling system and keep the mud property of circulation stable and mixture uniform.

Decanting Centrifuge used in oil industrial

Decanting centrifuge is one type of the screen centrifuge which belongs to the industril centrifuge. It is used in many industrial applications. During the solids control system matching to the drilling rig system, decanter centrifuge is a piece of equipment that is used as the fourth class solids control equipment.

 

Decanting centrifuge design consists of a solid container, called a bowl, which rotates at high speed. Inside the bowl tube, a screen conveyor rotates in the same direction, but at a slightly different speed. A differential gear is typically used to adjust speed.

Decanting Centrifuge Working Priciple

Decanting centrifuge is generally driven by an electric motor, that puts an object in rotation around a fixed axis, applying a force perpendicular to the axis. The centrifuge works using the sedimentation principle, where the centripetal acceleration causes more dense substances to separate out along the radial direction. By the same token, lighter objects will tend to move to the top.

How Dencanter Centrifuge Works

The drilling slurry is fed through a stationary pipe, which is inside a hollow shaft connected to a screw conveyor or scroll. The slurry enters a feed compartment located inside of the conveyor and is forced through discharge nozzles to the bowl section. Once inside the bowl, centrifugal force makes the material to separate. The screw conveyor moves the solids to the tapered end where they are discharged. Pure fluid flows out the other end of mud tank.

Dencanting Centrifuge

According to the rotary speed, decanting centrifuge could be classified to middle speed decanting centrifuge, high speed decanting centrifuge, and high speed variable frequency decating centrifuge, mainly separate 2-7 microns particle out.
