The Mud Gun’s Working Principle

Solids control service providers all over the world are common use the rectangular drilling fluid circulating tank for the reason that installation and migration performance of the system is very effective. At the same time, it doesn’t matter how good the mud agitator perform in excellent situation, the drilling fluid tank have the ability to corners that mud agitator’s propellers cannot reach and stir. In an effort to resolve this condition, install the mud gun in the top of the tank to agitate the far corner of the mud tank.

Mud gun functions as supportive machinery to the mud agitator. It comes along with nozzle that either made fixed angle or 360 degree ration angles the positive spray-effect distance of mug gun is approx. 3 meters long. The gun size is involved with drilling fluid density, viscosity and nozzle spray speed. Mud gun is mounted the top of the mud tank can be need adjusted as need whenever you want. The mud gun is connected with a motor-pump to stir the drilling mud and stop the solids from sinking on the base of the mud tank. The mud is mixed by being suck- withdraw into a pipe by a powerful pump and inject back into the mud tank by being pressured carry on the nozzle of the mud gun. The procedure is almost like how a jet sprays in the dish washer disposal.

Drilling mud is a wet mud like substance resembles like thick clay and is accustomed to retain the drill head in controlled-temperature and bear there mains of drilling cutting to the surface in water and oil and gas drilling operations. The mud is recycled and reused by passing it through several steps of filter and cleaning by screens of the shale shaker or mud cleaner and decanter centrifuge as it is circulated into the mud tanks then returning to the drill well on the drilling rig. So as to keep the mud as liquid-liked as they possibly can, a mud gun and mud agitator is utilized to keep the tank agitated and mixed. Drilling mud is made by mixing water and oil with a clay-like substance and also other chemicals.

Geothermal energy is thermal energy generated and stored in the Earth

Geothermal energy is thermal energy generated and stored in the Earth, means” earth’s heat”. GN solids controldesigned and manufactured mud recycling/ cleaning system can be used not only for oil & gas drilling, horizontal directional drilling, water welling drilling, diamond core drilling, rotery drilling, coal bed methane drilling , workover rig, but can be also used for geothermal well drilling.

They donot have much difference in drilling technology between geothermal well drilling and other energy drilling like oil & gas drilling, the important one is that the high temperature drilling fluids will damage the equipments, so you need a mud cooler to cool the drilling fluids. A mud cooler or a mud cooling system is an effective device to used for cooling the drilling mud in geothermal drilling or hot oil & gas drilling both in onshore and offshore.

GN mud recycling/ cleaning system for geothermal including the equipments below:

1 shale shaker: We adopt stainless steel shaker deck bottom which is Corrosion resistance, and the sealing rubbers on the shaker deck and under the shaker screens are also Corrosion resistance material.

2 hydrocyclones, we have 10inch hydrocyclones for desander and 4 inch hydrocyclones for desilter, the mud should go through mud cooler before feeding to the mud recycling system to avoid to shorter the service life of hydrocyclones and centrifugal pumps.

3 decanter centrifuge: GN solids control brand decanter centrifuge bowl assy is made of duplex stainless steel, and the other fluids touch parts are made of stainless steel 316L, which is Corrosion resistance and better strength.

GN solids control can design customized mud recycling system for geothermal project, with different treating capacity, wire height, mud tank size, qty and volume, what equipments to be used, etc.

Solids control equipment for 1000hp land drilling rig

GN Solids Control, as China top solids control manufacturer, exported 4 complete sets solids control equipment for 1000hp land drilling rigs to an North America drilling company. The drilling company also includes some replacement equipment for their previous land rig mud systems.

The order includes below solids control equipment:

1) Linear motion shale shaker model GNZS594E-HB, quantity 10 each

2) Vacuum degasser, GNZCQ270A, Quantity 4 ea

3) Desander mud cleaner,, quantity 5 ea

4) Desilter mud cleaner: quantity 7 ea

5) Different models centrifugal pumps, quantity 25 ea

6) Mud agitator,, quantity over 40 ea

7) Otherreplacement spare parts.

There are so many companies in China and out of China, why the customer finally choose GN after comparison?

1) GN Solids Control is the 1rst API certified solids control company in China. Now GN have CE certificate approved by DNV for European market.

2) GN is the first China solids control manufacturer who registered in Houston America and have a separate brand GN Solids America. All GN equipment made per international high standard.

3) GN company mission: Top brand and reasonable price. No lower, no higher.

4) As the fast developing company, GN think highly of customers’ feedback and keep improving quality and design.

5) GN centrifugal pumpinterchangeable with NOV mission pump. It makes customers easy for replacement and for stock spare parts.

6) GN have shaker model interchangeable with Swaco Mongoose and Derrick.

Besides mud solids control equipment, GN also make drilling cuttings treatment equipment. GN offer one-stop solution for drilling rigs.

Below is the main drilling waste managementequipment GN makes:

1) Drilling cuttings screw conveyer

2) Vertical cuttings dryer for both oil base mud and water base mud. The performance approved by jobsite test. While other brand, they can only be used for oil base mud.

3) High G drying shaker for water base mud

4) Dewatering unit for waste water treatment or water base mud treatment.

3500bbl Mud Liquid Plant for off-shore drilling

Mud System Compact Design for Easy Operation and Cost Saving

Almost all the large capacity drilling project need one set drilling fluids recycling system. While the drilling waste management system could also be classified as high configuration system and economic configuration model. The high configuration mud system is always be equipped for the oil drilling rig. This type mud system includes all the solids control equipment like shaker screen, de-sander, de-silter , vacuum degasser and decanter centrifuge. For some deep oil well drilling, the mud system may be consisting of many mud tanks for active mud storage. The economic configuration mud system is always used for some deep oil well drilling, work over rig project, horizontal directional drilling and piling project.

Work over rig mud system is little simpler in the solids control equipment configuration as the mud system sometimes only contain the shale shaker for one stage solids control. The workover rig no need the drilling mud to be treated very clean. It also has a mud mixing system which could be used to re-configurate the drilling mud.

According to the flow rate of the directional drilling rig, the HDD mud system is often divided into different model. Such as GN’s model 150GPM, 350GPM, 500GPM, 800GPM, 1000GPM and 1500GPM. The HDD contractor would always not use the decanter centrifuge in the system as the drilling fluid is not very high request on the cleanness. But some customers has high request, they will also put the decanter centrifuge in the mud system.

The piling system is the simplest de-sanding unit; it only has one tank and one unit high capacity de-sander. GN solids control could provide the piling system of D50 and D100 as per the treating capacity. Always the piling system is no mixing system, the solids is removed out by the vibration screen, and the fluids get down to the tank and the pumped back to the rig.
