De-sander with Double Layers Screen Panels Drying Shaker

De-sander is very popular equipment used in solids and liquid separation running. It always contains cyclone unit and steel framework. With different diameter of the cone body, this cyclone device could separate the strong particles with different sizes. GN’s de-sander is using 10 ” cyclones which could remove the solids size down to around forty five microns.
GN’s de-sander device is used in drilling business to separate the drilling cuttings from the drilling fluids. Conventional de-sander units don’t have the actual under drying shaker with regard to maximum recovery of the drilling fluids liquid, thus a lot of valuable drilling fluids had been lost. However , this type de-sander and even the de-silter device are very simple structure as well as cost effective.

To make the discharged solids much dryer, GN would rather suggest choosing the de-sander device with a under drying shaker which could recycle much more drilling fluids. This could reduce the waste materials discharges to environment and also the cost on drilling liquids materials. GN has a de-sander model with under drying out shaker of 2 layers displays panel. This unit is actually functioning as both main shale shaker and de-sander unit. The drilling liquids gets into this de-sander device via the mud supplier pipe and then flow at the bottom layer screen firstly with regard to primary solids control. Fluid gets through the screen nylon uppers and falls down to the actual under located mud tank. Large size particles will be released out of the shaker. And then the actual liquid will be transferred with a centrifugal pump unit towards the de-sander cyclone unit with regard to fine solids separation. The actual mixture of liquid and solids discharged from the cyclone can come to the upper layers screen for drying processing. Right here, to prevent the damage of screen mesh resulted by the powerful impact force of solids discharged out from the cyclone device, GN designs small barrier box to cover the store of the cyclone. This barrier box is small sufficient to make the unit more compact.
GN’s double-layer screen panel shale shaker can also be used as just primary shaker for a lot fine solids separation. Apart from de-sander unit, de-silter device can also use this type shaker as drying shaker.

Drilling liquids Bentonite and Barite

Drilling liquids is also known as drilling mud. It’s very important in drilling activities. It may lubricate drilling bits and remove drilling cuttings in the wellhead, and chilling the drill bits.

 

Bentonite and Barite are the normal chemicals utilized in fabricating drilling liquids for drilling rigs. However, many people don’t know the main difference from the 2 types of chemicals.

 

Here is a simple description from the 2 chemicals.

 

Drilling liquids Bentonite

 

Drilling liquids bentonite has good suspension property, thixotropy, low fluid loss, and also have good performance to obtain mud. It’s convenient for all, and simple to regulate the proportion of drilling liquids (drilling mud). With those characteristic, drilling liquids bentonite is the perfect base mud material for deep well drilling and offshore drilling activities.

 

Drilling liquids Barite

 

Drilling liquids barite can be utilized to weight the mud. In certain oil and gas drilling activities, normally, drilling mud and clay possess a proportion of 2.5, the proportion water is 1, therefore the proportion of mud is gloomier, sometimes mud weight can’t be balance using the subterranean oil, gas pressure. It may lead to blowout accident. In the situation of subterranean ruthless situation, it’s important to improve the proportion of mud. Its function measures to include barite into drilling liquids. Barite utilized for drilling liquids ought to be as fine as 325mesh or even more.

 

Drilling liquids bentonite and barite is putting on material for drilling activities. There’s an enormous use of them. To be able to save cost and stop pollution to atmosphere, solids control devices are utilized for drilling liquids recovery.

 

Solids control equipment is used for removing the drilling cuttings and doing drilling mud purification

 

4-stage Solids control equipment is utilized to recover the drilling liquids barite: Shale shaker, desander, desilter, mud cleaner, decanter centrifuge.

Water based drilling mud treatment

Water based drilling mud is one of the most widely used drilling mud in drilling area. In comparison with oil based drilling mud and artificial based drilling mud, water based drilling mud possess a smaller pollution on atmosphere; it’s relatively less expensive, and simpler to create the drilling waste.

Generally speaking, mainly 2 types of system will be utilized to water based mud in drilling area: drilling mud system.

Solids control equipment for water based drilling mud management system

1) The first step equipment shale shaker, recommend GNZS549E shale shaker

2) The 2nd and third step equipment mud cleaner. It’s a mixture of desilter, desander and under flow shale shaker for compact the design. Customer can select various model mud cleaner for every drilling capacity request. Sometimes every different jobsite request, customer can also select separate desilter, desander without or with underflow shale shaker.

3) The 4th step is the decanter centrifuge. The jobsite normally use lower speed decanter centrifuge, and/or perhaps a high-speed decanter centrifuge for fine solids control.

Drilling cuttings treatment for water based drilling mud

1) High G drying shale shaker, GNZS594HGE. It’s a four-panel shale shaker with similar alternative shaker screen with Swaco Mongoose shaker.

2) High speed Decanter centrifuge for drilling waste management system, having a telescopic skid underneath

3) Screw conveyer to deliver the drilling cuttings

In some instances, if you find an excessive amount of fine solids within the liquids phase from drilling waste decanter centrifuge, also it can’t be separated by decanter anymore, dewater unit is going to be utilized.

Dewatering unit with dewatering centrifuge is usually utilized for water based mud drilling cuttings treatment. It’s accustomed to supply chemicals to polymerize the fine solids into bigger size that centrifuge can separate.

After solids control separate, drilling waste separate, and/or dewatering treatment, the clean liquids could be moved to mud tank system for drilling. Or maybe there’s no drilling activity, the liquids could be moved directly to slurry separation company for waste water treatment.

Desilter general information

The desilter is the third step control equipment of the whole solid control system. Its function to deal with the solid debris with diameter of 15-44um, and to ensure a proper treatment of the processed drilling mud in the next step.

Initial preparation of the desilter

Put the desilter base horizontally and use four pressing plates to fix the base on a suitable place of the tank. Take a note that the outlet of screen box should be 20-30mm out of the tank.
Connect the inlet and outlet holes by hose or steel tube. The inlet pipe need to be fit with outlet pipe.

Loose four vibration bolts. When transport, the bolt need to be secure.
Check  there is any bolts that is loose. Check the vibration rotating axis is moving smooth. If there is any fault noise, the problem should be solved at that time. After all the initial check that all things are function properly, the equipment can be start to work.
Connect the belt with motor and turn on the power, check whether the rotating direction of motor is correct.

The operation of desilter

Start with the shale shaker first, then turn on the desilter. Check whether the exhaust pressure can match the requirements and check the results of desilting, check whether there is any possible of leaking.
Check  the rotating direction of motor is consistent toward to the arrowhead on the shield.
Check the pressure gage works properly in a allowed pressure range.
Adjust the bottom flow nuts to make the bottom flow jets shoots the mud out smoothly.
When stop the operation, the drilling fluid should be cleaned out to avoid solidification. Clean the shaker screen with water and check each part.

The maintenance of desilter

Check and confirm the connection and sealed parts.
Check the cyclone cylinder to see the jet situation and pressure.
Repair or change the damaged, leaking or abraded cyclone cylinder.
Check whether the jet nozzle is broken. Check the inside of the cyclone cylinder and if need, change the damaged parts.
Clean the feed head.
When stop using for period of the long time, every parts that contain drilling fluid should be cleaned through, avoid stockpile of sand inside the equipment.
The lubricating grease should be injected into the vibration motor every 1500-2500 hours. The volume to be injected each time is 5-10ml.
When stop using, the shaker screen should be cleaned with water to avoid solidification to ensure max useful screen life.

Oilfield Drilling Rig Composition and Mechanical Transmission System

Drilling mud solids control system to some extent could be seen as part of the complete drilling rig system. Comparing with the main body of drilling rig, the shale shaker has a more frequent maintenance and replacement. Now let talk some on the composition of drilling rig.

 

According to the requirement of drilling, wash well and unloading the drilling tools in the drilling process, one set of drilling rig must be equipped with the following systems and devices.

1. Power equipment: diesel engine or AC, DC power source.
2. Driving system: including reduction, parallel operation, reverse and speed changing etc. On the basis of mechanical transmission, still need hydraulic transmission, pneumatic and electromagnetic clutch, etc.

gn functionality and cost benefits

Functionality Report: Brazil: One certain GN-3 Shaker Outshines 3 in Profitable South America Debut

The new-generation GN-3 triple USA desilter was engineered to supply operators an ideal mixture of higher efficiency, adaptability, enhanced operate atmosphere and reduction in space specifications. Operating in each the progressive and balanced elliptical motion, the compact GN-3 shale shaker is exceptional in that it may well adapt speedily as drilling situations and cuttings volumes modify.

To quantify the functionality and cost benefits of the GN-3, when compared with conventional shale shakers beneath the ever-changing drilling circumstances and specifications, an aggressive comparative field trial was undertaken about the Diamond Ocean Star semi-submersible rig, which generally employed 4 cascade shakers. The test may very well be carried out throughout the remainder inside the OGX 1-OGX-28-D-RJS exploration correctly in Brazil?ˉs Campos Basin. The field test represented the initial use around the GN-3, offshore in South America.

For the comparison, one unique of one’s current rig cascade shakers was removed and replaced with an GN-3, which was installed with no HSE incidents. This configuration allowed the three rig shakers to become applied in conjunction with all the GN-3, because of this enabling the collection of aggressive comparison information and facts. The key objectives in the test had been:

Test the flow handling capacity in the GN-3 desilter in comparison using the existing rig cascade shakers.

Prepare a qualitative assessment around the solids handling and conveyance capacity around the GN-3 shale shaker in comparison with the current rig cascade shakers.

Measure the screen life of your GN-3 shaker and examine it towards the screen usage of the existing rig cascade shakers and historical GN-3 screen usage data 3 tests had been performed which involves all round functionality, screen life and QHSE perspectives, the single GN-3 shaker surpassed the three existing rig shakers in all the head-to-head comparative evaluations. Even when outfitted with bigger API designation screens, the GN-3 did not expertise the regular flow restrictions within the previously employed four-cascade shaker configuration and correctly processed in the complete nicely flow cost. The GN-3 exhibited its capacity to adapt conveniently towards the rapid ROP encountered in each the top rated and intermediate successfully intervals.

For the duration of drilling from the 12 ? in. section, all the shakers removed a cumulative 561.75 bbls (89.311m3) of cuttings, excluding any washout around the open hole. The single GN-3 shaker processed 75%, amounting to 421.31 bbl (66.98 m3) from the total cuttings removed within the 12 ? in. hole, even though the 3 rig cascade shakers combined processed the remaining 140.44 bbl (22.33 m3).

Further, throughout 12 ? in. interval, the screens with all the 3 existing cascade shakers skilled catastrophic failures, even though the GN-3 screens were repaired very simply and returned to service. Whilst the GN-3 processed 75% of one’s total flow in each the intervals tested, in comparison with all the three cascade shakers it accounted for only 33% in the damaged screens that had to be scrapped. When calculated for comparative screen life, the GN-3 screens realized a 12-fold higher service life and utilization compared to the rig cascade shaker screens, thereby saving drastically in connected screen cost.

The general general overall performance with all the GN-3 via the comparative field trial was practically nothing at all speedy of exceptional, effectively validating its operational and economic benefits. Via the trial, a single GN-3 appropriately processed nearly 300 additional bbl of cuttings than 3 cascade shakers combined employing the utmost in reliability and screen life.
