Maintenance of solid control system 2

11, Clean sand work or high pressure mud gun line, the jet pipe valve should be open , and then open the main valve upstream pipeline , should stop first and then shut off the main valve jet pipe valve , in order to avoid high-pressure jet off to die in the pipeline .

 

12 , When the mud gun work , if found around mud gun did not flip phenomenon , you should check whether the lower nozzle exit is blocked.

mud tank13 , Found flanges, valves , fittings should be checked for leaks repair or replacement.

 

14,If you find Steel by the leakage of first threaded tight , if it is still valid, then check the reason or replacement parts. When found pneumatic tire union dropout, first gassing check whether the pressure is too low or not, emergency treatment should be carried out with cotton or other plug-soft material loss plugging the gap until the mud tank is no mud, replace the pneumatic tire.

15, lifting equipment, wire rope to coat on the ears.

 

Solids control equipment play a very important role in oil exploitation,and the maintenance of solids control is also a very important part for its purification handling .Following are some skills used in purification of solids control equipment.

Maintenance of solid control system 1

1 , Regular cleaning and shaker cone positions , excluding grit .

2, If stop using the shale shaker , immediately rinsing with water , used non- metal tools to clear debris in the sieve .

 

3,150 centrifugal oil ring filled calcium butter, Turn the 1/2 circle in each shift , lower casing plugs row of sand once every 24 hours , Use clean water pump after each stop the pump.

4, After long-term storage the mud in the tank, before start the mud agitator, mud gun should be used first sedimentary mud sand scattered around mud mixer impeller, otherwise it will make the agitator overload and damage.

 

5, Before you start the mud agitator, first to check whether there is enough lubricating oil in the reduction gearbox, according to the provisions added in sufficient quantities.

6, You should check whether the lubrication of mechanical parts is normal often, the oil change once every six months and pay attention to prevent frostbite.

7, Looking for mud gun joint leakage often, such as leakage, should replace the sealing ring, union disassembly cleaning once every six months, add calcium base of butter at teleflex, and check the sealing ring wear degree.

 

8, After each played well, must be removed the sand tank, rinse with water or steam slurry pipeline.

9, Mixed with funnel, application of clear water is rinsed clean.

10, Desander and drilling fluid shale shaker must be used at the same time, the lower cyclone underflow nozzle must often be adjusted depending on the granularity of debris .

Oilfield solids control pumps

The drilling mud can be pumped by horizontal centrifugal pump, or the vertical centrifugal pump. We also may call it slurry submersible slurry pump. Some clients will also request the screw pump for feeding decanter centrifuge.

 

 

In fact, during communicate with clients; we’ll propose proper pumps or configuration for them. Upon their satisfaction on both technique and cost we’ll confirm the optimal solutions on pumps and every other issueThe mixing pump and shearing pump? They have similarity. Both them are combined with centrifugal pump and another part. And they both can mix / compound drilling fluid for solids control system.

 

 

The mixing pump is including the centrifugal pump and mixing hopper, which can be venture hopper or vortex hopper.?While the solids control shear pump including the centrifugal pump and over-head belt.

mud mixer hopper

Yes, another pump is the trip pump. It is also centrifugal pump. And we set it on the trip tank. It can supplement drilling fluid for shaker or the former equipments.

Oilfield solids control pump

Solids control system in oilfield is the typical 4 phase mud process system including shale shaker, desander, desilter, centrifuge. What is the pumps info? What is solids control pump detail?

 

 

As per complete close loop solids control system, there is feeding pump for hydrocyclone separators, the mud transfer pump for charging centrifuge, the drilling fluid mixing pump for configuration, and/or the shearing pump for shredding drilling mud, the trip pump, etc. We also can say, there is horizontal pump, vertical pump, screw pump, etc.Different equipments request different pumps as power resource or mud supplies. Meanwhile, different solids control system configuration will have different pumps position, design, or types.

 

 

Detail pump in oilfield solids control

For solids control equipments, the separated hydrocyclone separators or mud cleaner we must match centrifugal pump as mud feeding pump. The centirfugal pump transfer drilling fluid to the cyclones inlet line for subsequent process.Usually, these pumps are horizontal one. They’ll be mounted on mud tanks ends or under the slant plate of shaker tank. ?When we set pumps under shaker tank will save much space. However, then it will be inconvenient when we repair or inspect pumps.

 

 

But sometimes in solids control system there will be vertical pump or submersible slurry pump instead of horizontal pumps.We know in solids control system, the drilling mud seems blood to our human body. While pump will be the transfer tools. They pump drilling fluid from here there between different drilling fluid tanks or compartments.Let’s see, after mud cleaner or hydrocyclone desilter what pumps there? Yes, the 4th solids control equipment-Decanter centrifuge. For decanter centrifuge, we need pump transfer drilling fluid from desilter compartment to centrifuge input.

Poor boy degasser

We manufacture mud gas separator in oilfield drilling mud cireculation system .Mud gas separator is also called Poor boy degasser, Gas-Liquid separator. It captures and separate large volume of free gas within the drilling fluid. If there is a “KICK” situation , this vessel separates the mud and the gas by allowing it to flow over baffle plates.The gas then is forced to flow through a line and vent it to a flare. A “KICK” situation happens when the annular hydrostatic pressure in a drilling well temporarily (and usually relatively suddenly) becomes less than the formation, or pore, pressure in a permeable section downhole, and before control of the situation is lost.It is always safe to design the mud/gas separator that will handle the maximum possible gas flow that can occur.

Mud gas separator

Brightway series Mud gas separator 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.?Brightway mud gas Separator combined with the Flare Ignition Device can be used to ensure the drilling process smooth.It is devided into the normal pressure mud gas separator and pressure auto-control gas-liquid separator, according to the pressure.Mud Gas Separator is your best choice to prevent drilling fluids invasion.

 

 

The principle behind the mud gas separator is relatively simple. The mud and gas mixture is fed at the inlet allowing it to impinge on a series of baffles designed to separate gas and mud.The free gas then is moved into the flare line to reduce the threat of toxic and hazardous gases and the mud then discharges to the shale shaker and to the mud tank.Gas-liquid separators in other countries also called Poor boy,Liquid-gas separators,Mud/Gas Separators, etc.

Drilling Mud Decanter Centrifuge

Drilling fluid decanter centrifuge used for recovery barite to remove small solid particles, reduce the mud solid content, to ensure the performance of the drilling fluid. And Brightway supply drilling fluid centrifuge has high purification efficiency, convenient adjustment and easy maintenance .

decanter centrifuge

The drilling fluid decanting centrifuge is driven by two motors. The main motor drives the drum and differential shell rotation by the belt . The vice motor drives the spiral through the differential variable speed . The drum and spiral rotate together in the same direction, but at different speeds . Separate the solid phases in the drilling fluids by the centrifugal sedimentation principle.

decanter centrifuge

Suspending fluids is pushed into the rotor drum through the inlet pipe and under the force of screw propeller, under the effect of centrifugal force, the solid phases will be pushed onto the inside wall of the drum, pass the impeller on the screw propeller and be discharged from the exhaust hole at the small side of the drum. The fluids is excreted from the overflow hole of the large end. So continuous circle like above to achieve the target of continuous solid-liquid separation .

decanter centrifuge

 

Brightway LWF Series decanter centrifuge adopts centrifugal force to separate solid particles out of drilling fluid. Different solids or particle have different density and flow speed, some decanter centrifuge also can separate particles as different size and density. Brightway LWF decanter centrifuge is widely used in oil and gas drilling,chemical,foodstuff,pharmacy,mineral beneficiation,water treatment,etc.Brightway also manufacture other solids control equipment.If you want to know more informations ,feel free to contact with us.We will do our best to serve you.

What kind of Shale shaker is the best?

Shale shaker is components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling.They are considered to be the first phase of a solids control system on a drilling rig, they are used to remove large solids also called cuttings from the drilling fluid, more commonly called “Mud” due to its similar appearance.

 

 

Drilling fluids are integral to the drilling process and, among other functions, serve to lubricate and cool the drill bit as well as convey the drilled cuttings away from the bore hole. These fluids are a mixture of various chemicals in a water or oil based solution and can be very expensive to make. For both environmental reasons and to reduce the cost of drilling operations, drilling fluid losses are minimized by stripping them away from the drilled cuttings before the cuttings are disposed of. This is done using a multitude of specialized machines and mud tank.

 

 

Shale shakers are the primary solids separation tool on a rig. After returning to the surface of the well the used drilling fluid flows directly to the shale shakers where it begins to be processed. Once processed by the shale shakers the drilling fluid is deposited into the mud tanks where other solid control equipment begin to remove the finer solids from it. The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal.

 

 

Shale shakers are considered by most of the drilling industry to be the most important device in the solid control system as the performance of the successive equipment directly relates to the cleanliness of the treated drilling fluid.
