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.

The five stages of solids control equipments 2

Second stage solids control equipment: vacuum degasser

Vacuum degasser separate H2S and other gases. It is helpful for reducing cone part abrasion on desander and desilter during further handling.It also can beused as mud agitator with big power.

Third stage solids control equipment:Desander

Desander is used for separating 45-74μm particle from drilling mud. It is adopted with flexible and replaceable cones for option ( 1pc to 3pc,dia 10″ or 12″).Good wear resistance for cone material with PU and high-chromium iron for option.Smaller size motor and lower position deck,making sure lighter participating vibration weight,getting bigger treatment capacity.

Mud Cleaning System for Diamond Drilling

Diamond drilling is becoming more and more popular now as following the diamond stone get cheapper and cheapper .

 

Diamond core drilling uses a diamond bit, which rotates at the end of drill rod (or pipe).  The opening at the end of the diamond bit allows a solid column of rock to move up into the drill pipe and be recovered at the surface.  Standard core sizes are 7/8 inch (EX), 1 3/16 inch (AX), 1 5/8 inch (BX) and 2 1/8 inch (NX).

shale shaker

Most drill rods are 10 feet long. After the first 10 feet is drilled, a new section of pipe is screwed into the top end, so the combination of pipes can be driven another 10 feet into the ground.  The diamond bit is rotated slowly with gentle pressure while being lubricated with water to prevent overheating.  The drill depth is estimated by keeping count of the number of drill rods.

mud agitator

 

For diamond drilling , its required treating capacity is allways small . One diamond drilling company ordered us a 500liters/minute mud cleaning system without tank for diamond drilling mud cleaing . One mud cleaner with desander and desilter cyclone and feeding pumps for desander & desilter . This mud cleaner and feeding pumps is one the first parts we calling processing part . One jet mud mixer with  pump and a mud agitator on the mixing part .

Choose a Suitable Cyclone Desander

In drilling fluids treatment, a cyclone desander is an essential equipment. Is it wise to choose a cyclone desander without considering situation? Absolutely not. Then, how to choose a suitable one? Which aspects should you pay attention to when selecting this type of solids control equipment. Read the following article and you will find it very useful.

desander

The selection of cyclone desander must consider the treatment of water, outer diameter, working pressure of pipeline, water quality and water quality requirements after the treatment and other factors. In general, when choosing hydrocyclone desander, the premise that meet the flow, give high priority to the use of large equipment, and recommends the use of parallel several sets of equipment in the system instead of large equipment,in order to obtain the better effect of separation of solid and liquid.

 

Desander, based on φ 300 mm diameter hydrocyclones, added with shale shaker, all the liquid can be discharged recovery underflow phase, and the solid particles of underflow outlet automatically sent. Φ 300 mm diameter hydrocyclone the upper part of the shell structure is reasonable, is conducive to the solid-liquid separation.

shaker screen

The cone is a wear resistant cast iron casting, good wear resistance, convenient replacement. Drilling fluid vibration of double motor excitation is equipped with a sieve, convenient repair and maintenance, the screen using crochet tension, tension force uniform, convenient to replace the shaker screen.

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.

Linear Motion Mud Cleaner

Mud cleaner has an efficient solids-fluids processing design, which consists of a linear shale shaker, desander with two 10” cones and a desilter with twelve 4” cones primarily used to eliminate 20 – 76 microns of sand and mud in the underflow.

 

 

The drilling fluid will firstly pass the desanding cyclones or desilting hydrocyclones for separation, with overflow returning to the circulatory system and the bottom flow screened and treated by the vibrating screen. If necessary, the vibrating screen of the integrator could be used as the forestage vibrating screen.

 

 

drilling fluid desanding and desilting integrated mud cleaner, or integrator for short, is used for separating the solid-phase granules in the drilling fluid after treated by the shaker screen.

 

 

Brightway compact,multi-functional mud cleaners are designed to be operated as both a double-deck drying shaker / mud cleaner or double-deck flowline shale shaker. The built in multi-functional  feature allows the operator to handle varying drilling fluid viscosities and solids content with the same unit. In the dual simultaneous flow mode, the top deck handles the hydrocyclone underflow and the bottom deck handles the primary scalping.

The processing ability of the hydrocyclone

Brightway desander is solid management second level system of solid management instrumentation, the most role is to solid particle filter 47~76um. Sand removing cyclone relies on the principle of centrifugal gravity to get rid of solid particles in drilling muds. lubricating substance is fed into the impact of sand removal when Cyclone For mation of swirl flow in cyclone, cyclone mud is mirrored all told directions, by centrifugal gravity made, deposition of solid particles within the vertebrae at the hydrocyclone, the bone body discharge to the vibration sieve. And was refined from the higher a part of the lubricating substance pipes into a suspension storage mud tank solid system.

Besides the benefits into sand hydrocyclone is: import and export manifold with fast joints connecting (maintenance), has the benefits of easy structure, quick replacement, handling capability of sturdy moving flow. The disadvantage isn’t effectively the solid is separated into 2 size vary obvious.

Cyclone sand process capability depends on the scale of the cyclone for removing sand and dust consistence. If the hydrocyclone underflow adjusted, to cyclone for removing sand input while not consistence liquid, no consistence liquid from a suspension pipeline is discharged; and therefore the relative with solid separation, liquid input solid particles discharged from rock bottom outlet, whereas the cyclone below the excretion export adjustment is that the key.

hydrocyclone

 

If the hydrocyclone desander bottom outlet, diameter relative to the balance between zero corresponds to the diameter is just too little and therefore the balance purpose underflow mouth edge region are going to be fashioned while not liquid zone, the alleged non liquid zone is between the equilibrium points and outlet edge solely in solid sand,vertebral wall than the drier. once little gravel lose wet, are going to be terribly straightforward to adhere to the inner wall of the cyclone on the block, this is often not the wrong adjustment mode is named dry bottom. If the discharge port adjusting diameter is larger than the comparable to the equilibrium purpose diameter can result inleakage, the error adjustment that’s referred to as wet bottom

How to installed the desander and desilter?

Desander and desilter two main solid control equipment is installed in its above except mud and grit removal cyclone cyclone, cyclone separator solids are not the same diameter . Hydrocyclone separation and processing capability of the cyclone barrel diameter. The barrel diameter of the particle size , the greater the separation . Separation of the particles on the other hand the less , the general current Desanding cyclone size of 10 inches, except for the 4-inch mud cyclone .

Cyclone commissioning and maintenance There are three ways :

A cyclone in the installation of the first to do relatively flat platform , the device can also be mounted on a flat surface. Device bolt which is fixed on the base on the ground or other stable platform , installed by conducting the cyclone .

 

2 , The equipment should be noted that at the time of installation of the direction of the desanderinstallation , there is a left-handed or right-handed look .

3 , When attached to the surface of the mud tank , should be taken into leaving space for installation personnel operations. Since the device has no moving parts in the working process, so that the device can be little maintenance . But the need to pay attention to maintaining the stability of the inlet pressure to avoid too much pressure or too small , over the General Assembly to make the cyclone barrel drum up even burst pressure is too small will lead to run pulp.

shale shaker

Second, in the debugging process desander should pay attention to :

1 , Hydrocyclone desander position should normally be installed after the shale shaker , have the same flow pump to supply its pulp .

2 , The device is stopped for a long time or seasonal outage until stopped , put the right amount of corrosion inhibitor in water , and the use of appropriate protective measures to reduce corrosion protection system.
