As a leader of solid liquid separation plants in China, GN Solids Control now march to piling field, GN50 is the first desanding plants for piling, and it will be exported to Pakistan. GN also can supply GN 100 (treating capacity 100 cbm), or other customized desanding plants.

Desanding plants are also a very important part of liquid solid separation, and GN 50 can also applicant in other fields, like mining industry, well drilling, deep drilling and so on.

The main components of all desanding plants are: Coarse screen for intercepting stones larger than 5 mm;  Storage tank of the coarse screen;  Cyclone with cyclone feeder pump for removing fine particles from the suspension; Dewatering screens for abstracting further water from the solids dis-charged by the cyclone. GN 50 use high efficiency linear motion shale shaker, with OLI brand motor, high quality centrifugal pump.

Submersible mud agitator is also used widely in oil & gas drilling, for the drilling work is usually complicated. To prevent

sedimentation, that is why we use mud agitator, but the suspend type is not usually suitable for all kinds of condition.

Drilling mud is composed of extremely small particles and has a thick consistency. Its settling velocity is therefore low, and sediment should not be a problem if the contents in a tank can be kept in motion. But, due to the combination of the irregular shape of tanks and the inefficiency of conventional mixing systems, sediment build-up is a timeconsuming and expensive problem.

Features and Advantages:

•   No sedimentation – the agitator suspends the solids, counteracting the mud’s tendency to stratify.

•   Full tank volumes – by preventing sedimenta-tion, the full volume of a tank will always be available, allowing for prolonged drilling opera-tions.

•   No manual clean-out – ends time-consuming and expensive manual or mechanical removal of sediment.

•   Problem-free pumping – with well-mixed drill-ing mud, problems are avoided when pumping the mud.

•   Monitoring and control – we supply monitoring devices, for full operator control.

•   Faster batch productivity – the combination of high turbulence and high flow results in fast batch turnover.

Applications:

Submersible, then it must be used in tanks, or something alike. Mud tanks in supply ships, drilling rigs, mud plants.

Professional at solids liquids separation, now GN road to the piling field. In Desander for Piling construction, we introduce the piling slurry recycle and the process of the piling slurry treatment. Now we are going to talk about the application and the desander for piling in the piling construction system.

Piling Introduction

Foundations relying on driven piles often have groups of piles connected by a pile cap (a large concrete block into which the heads of the piles are embedded) to distribute loads which are larger than one pile can bear. Pile caps and isolated piles are typically connected with grade beams to tie the foundation elements together; Continue reading “Piling Slurry Treatment”

The main function of the mud system of ZJ50 drilling rig is: recycle, clean the drilling fluids with debris from the wellhead. this system can eliminate sands less than 7μm in size, and supply drilling rigs with satisfied drilling fluids.

1． The installation

Level off the work site, set a good base. As show as figure 1 : install and fix GNPS70-3S shale shaker & ZQJ250 × 3 / 100 × 16 mud cleaner and jet mud mixer SLH150-50. connect all manifolds ,walkways, guardrails ,ladders, etc.. Ensure all parts flexible and on the good site. Connect inlet manifolds as showed. Connect all the solids control equipment control circuit connectors.

2. Working process of the recycling system

Firstly, start up the shaker box locking device of GNPS70-3S shale shaker & ZQJ250×2/100×16 mud cleaner (as to its operation please refer to the related user manual), and have a trying operation. And ensure all valves not been blocked . The butterfly vavles should be shut up while connecting the mud cleaner pipes. Send drilling fluids to the mud cleaner while bigger capacity needed.

Then, start up GNPS70-3 shale shaker & ZQJ250×2/100×16 mud cleaner. Continue reading “ZJ 50 Mud System Operation”

Driller mud system and GN Solids Control both are very famous drilling equipments company. Here I am going to compare these two companies.
Drillers Mud Systems, LLC offers a variety of mud pumps, mud mixing/ recycling systems, spare parts and tooling designed to fit in Horizontal Directional Drilling or Oilfield applications. It can supply all of HDD or drilling needs.

GN Solids Control (Tangshan Guanneng Machinery Co.Ltd) is a company focus on solid liquid separation. We can supply all kinds of solids control equipments for oil & gas drilling, mud recycling system for HDD.

Slurry pump is widely used in oil&gas drilling work, mining programs and so on. Variable Frequency Drives Slurry Pumps is one kind of slurry pump, and main body is the same with other slurry pumps. And it usually not used so widely as usual ones.

Any way if you need to choose a right Variable Frequency Drives Slurry Pumps, firstly choose the right pump, then the motor, then maybe control panel is needed.

GN Solids Control supply kinds of slurry pumps for all kinds of application, especially in oil and gas drilling. If you want to get the right model from us, usually you must supply these informations:

1.the productivity (flow) you required;

2. the lift you required, or the envioment in your work site, is there any difference in height of the related equipments and others (mud pits for example).

3. Do you need horizontal or vertical pumps?

4. Importantly do not forget to what kind of material you are pumping, if it contains something like H2SO4 or other corrosive materials. Continue reading “Variable Frequency Drives Slurry Pumps”

There are three kinds of drilling fluid, oil based fluids (OBF’s), synthetic based fluids (SBF’s), water based fluids (WBF’s). Every coin have two sides, three ways have there own advantages and disadvantages, but for water based fluids, one important factor is: enviomental friendly, while not delivering optimal performance in more challenging drilling conditions.

Enviomental drilling fluid is water based fluid, no need any biologichal process. Just screening, hydrocycling, decanting, and so on, only mechinical separation.

As an ISO & API Certified company specilize in mud circulation system.Following GN Solids Control introduction of mud circulation systems.
Function of Mud Circulation System
A fluid called mud circulates through the drilling bit as it cuts through rock. The fluid lubricates the bit, removes rock cuttings, stabilizes the wall around the hole, and controls the pressure in the wellbore. The mud is a suspension of chemicals and minerals, such as bentonite clay in water or sometimes oil.

Processing of Mud Circulation System
Workers blend the mixture in the mud-mixing shack. The mud pumps push the fluid up the standpipe and into the drill pipe through the kelly, or through fittings in a top drive mechanism. After passing through the drill bit, the mud and cuttings circulate back to the surface through the space outside the pipe, known as the annulus, and into the return line.

The shale shaker, a vibrating screen, then separates the cuttings from the mud. The cuttings flow into lined pits or tanks, while the drilling mud flows through the de-silter and is recirculated. More fluid is added through the mixer as the drilling progresses to greater depths. When drilling is completed, the remaining fluid is trucked away for disposal or reuse at another site.

Decanter centrifuge is one part of the solids control system, and sometimes it is used separately, for diamond drilling works, some coring works in mining industry, other drilling works with small debries.

As we know, in solids control system for oil&gas drilling, after the third phase, the desilter, debries bigger than 30 (15-47) microns are cleared out.

Once a client told us that they use mi swaco 414 with tank as a centrifuge system for their diamond drilling, we find we producing the equivalent one, LW220. So after proved with our experenced engineer, then re-researched by the cooperation universities, we manufactured our own centrifuge system for diamond drilling. LW220 with mud tank. Rugged design, compact body, efficient solution.

The differential gear type is mechanical differential, and the treating capactity is ≤ 150lpm, which means the maximun capacity is 150lpm, and you even can use this to handal the drilling mud with about 20lpm.  Other specific is as shown below:

Drum diameter: 220mm

Rotary speed:1500~4800rpm (Variable Speed)

Extruder rate L/D: 4.3

Separation factor: 2800G

Motor power(explosion proof)：main power：11kw；Assistant motor: 5.5kw

Dimension ：2020×1080×755mm

Weight ：1000kg；

Operation period：continuously 24hours
