Suitable Mud Gun for Solids Control System

In a complete oil and gas drilling solids control system, there is not only main equipments like shale shaker, desander, desilter, mud cleaner, and decanter centrifuge, there are also auxiliary equipments that play certain roles in the whole procedure, like the mud agitator, mud guns and mixing hoppers, and also the pumps for feeding including centrifugal pumps, submersible slurry pumps and shearing pumps.

The auxiliary equipments’ performances also affect the treating efficiency for the whole system. GN Solids Control, as the TOP solids control manufacturer in China, always sticks to its belief: Quality first, Price second. Even the mud guns, GN Solids Control also provide the best ones.

Mud Gun

GNNJQ series mud guns have following main benefits:

1. for the mud gun nozzles, GN use polyurethane as material, for a better wear proof result and a longer service life. Unless other Chinese suppliers, who mostly use the metal like steel for the nozzle material, Polyurethane is for sure a better choice. Just like the hydrocyclones for desander or desilter, before, the manufactures all use steel ones, but now the high standard solution is the polyurethane ones, the service life is greatly prolonged.

2. GNNJQ series mud guns also suitable for higher pressure condition, its largest pressure is up to 6.4Mpa, which is the standard of high pressure mud gun. GN use this as standard level in order to provide more cost-effective choice for the clients, and of course, the safer usage.

3. the main body of the mud gun is made of national standard steel from reliable supplier. GN Solids Control always buying from large supplier with good reputation.

 

For other GN products also, like the bearings, GN uses SKF, FAG or NSK, the vibrating motors for shale shakers, GN uses Italy brand Oli or USA brand Martin. And for the design and manufacturing, GN has 10 patents already and another 5 pending. And GN QC department is always serious in inspecting the semi-products and products.

HDD usage of mud cleaning equipments

The technology of trenchless digging is developed from directional drilling technology, require very small area of surface for the construction.  it only needs very small inlet and outlet area excavation. All kind of underground replacements of the pipeline construction start adopt this technology for minimum interference of surface have high effect of keep the cost in control.

In 1970’s the technology was developed and now is widely use on horizontal directional drilling, piping, tunnel digging, piping type of detonation are some use this method.  Now are widely use in water supply and drainage.  Laying power, gas, communications lines. Any type of pipeline construction and repair of old pipeline.  The archaeology use this method of digging to minimal disturb the ancient structures.

Hydraulic Jackup Mud Recycling System

Horizontal directional crossing (HDD-Mud Recycling System) technology in oil and gas industry are laying pipeline across waters like river and lake.  The hub of railroad obstacles and areas has important function  that cannot be disturb is obvious using through Horizontal Directional enlarge hole that common diameter of pipe in 1.5 times larger.

The method of solids control principle used in Horizontal directional drilling is the control of mud solid phase technology.  The technology purpose remove the harmful mud, solids and keep the good solids through process on mud filter and cleaning requirements.  The current use of horizontal directional drilling, the recovery mud solids control is system composed from small to large as end user requires.  The choices of mud solids control system is need according the basics in below:

 

It needs to be clean or inhibit particle variable types and size

It need to be maintain the quality of the mud

The size of ability in drill, removal of solids and operation cycle rate.

 

Solids control system function as environmental protection system that is requires in every region of the world who are digging in to earth to harvest resource underground.

Efficient and Flexible Mud Units for HDD Drilling Rigs

It is known to all that for the oil and gas drilling projects, there must be a solids control system for separating out as much as solids cuttings, but in HDD projects, in many places in the world, the separation unit is not a legal request.

Recently, more and more countries are establishing laws requesting the mud recycling system or mud recycling units, and some clients, although their countries have not yet established such laws, the company owners decided to use mud units for their drilling works, because of below benefits a mud unit provide:

1. greatly save the usage of materials, including water, bentonite and polymer

2. save the drilling cost by lower down the discharge disposed.

3. responsible for the surrounding and environment friendly.

Hydraulic Jackup Mud Recycling System

What’s the main equipments for a HDD mud system?

For a high standard configuration, there are 3 steps separation and 1 step of mixing, the separation equipments include: 1. Shale shaker, 2. Desander, 3. Desilter. In order to save space and make the mud unit more compact, there is always a mud cleaner playing a role as combination of desander and desilter. And mixing system is a jet mud mixer consisted by a mixing hopper and a centrifugal pump for feeding.

Of course, per different jobsite condition and composition of mud, end users could change the solution, some use without desander, some without desilter. And some adds equipments for a further and cleaner separation with a decanter centrifuge and even a dewatering unit.

 

GN Solids Control is the most professional solids control manufacturer in China who designs and produces mud systems for HDD drilling and other drilling projects. GN has a series of available capacities, not only high configuration, but also economic configuration, from 150GPM to 1000GPM for HDD, CBM, TBM and Piling or water well drilling.

GNDC-40A Waste Management System for Russia

GN Solids Control is the first manufacturer for waste management systems which are accepted by Russian market. Just a few days ago, GN has delivered a complete set of waste management system to Russia. Now, GN’s vertical cuttings dryer and its waste management systems are most popular among the end users. Although it is a tough year for all the oil relating industries, GN also sells lots of waste management systems to the clients and receives good feedback.

GNDC-40A Waste Management System
GNDC-40A Waste Management System

GNDC-40A is one of the 2 standard drilling cuttings waste management systems GN designed for different jobsite requests. GNDC-40A is more suitable for the waste management jobsites which are alongside with the drilling rigs, in this system, there is no tank for containing the liquid phase from the centrifuge, and the centrifuge is hosted at a certain height so that the liquid discharged from the centrifuge flows directly to the active tank of solids control system easily. And when matching with an effective set of solids control system, this drilling waste management system could work continuously.

GNDC-40B is another standard design of drilling waste management system designed by GN Solids Control. It is more suitable for the mud companies or somewhere specially for treating the drilling waste cuttings. In some countries, there is no need for a drilling jobsite to have a waste management system, and the drilling cuttings are transported and collected in a special place for further treating. In this case, we use GNDC-40B, which has a tank for the liquid discharged from vertical cuttings dryer and another tank for the liquid finally discharged from the centrifuge.

Besides above mentioned 2 kinds of standard drilling cuttings waste management systems, GN also has the individual modules for waste management equipments, vertical cuttings dryer, high-G drying shaker and high speed decanter centrifuge, each one could be regarded and used separately. In the coming CIPPE Shanghai, GN will show such modules, welcome to come and see.

Drilling Waste Cutting Management System Onsite Layout Types

Drilling waste cuttings management equipment is more and more used in the drilling industry nowadays. The main cutting drying equipments are the vertical cuttings dryer, drying shaker and high speed decanter centrifuges the cuttings transferring system. According to the different base of the drilling fluids and the cuttings transferring equipment, the drilling waste cuttings management system has several layouts onsite.20150421101534830

Almost the waste cuttings waiting for treatment are collected from the primary drilling solids control equipment like the shale shaker, de-sander, de-silter and barite recovery centrifuge. According to different transferring equipment, the different collection equipment would be used. If the user choose to use the auger as the cuttings delivery equipment, it is better to use the auger also as the waste cutting collecting equipment. The auger is located horizontally at the side of the solids control system mud tank; the length of the auger is decided by the mud tank length. The collected cutting was delivered to the drying equipment by another auger unit. If the user chooses to transfer the cuttings by using the slurry hose pump, then the cutting could be firstly collected by a hopper unit which is connected with a hose pump, the hose pump could transfer the cuttings to the drying unit through the hose. Using the auger would occupy much of the area of the drilling site, while the hose pump could be installed freely with less limitation of space.

As per different base of the drilling fluids, the vertical cuttings dryer or the high G drying shaker would be chosen. GN’s modular design vertical cuttings dryer is the main cuttings drying equipment for oil base cuttings, the effluence out from the dryer is stored firstly in a intermediary tank, then the effluence will be pumped to the waste decanter centrifuge for polishing. The water base cutting mostly transferred to the high G force drying shaker for treatment. GN’s modular design drying shaker unit has a beneath located catching tank for drilling fluids storage and pumped to the centrifuge for further treatment.

The decanter centrifuge could be installed on a telescopic skid, thus the active drilling fluids could flow back to the mud recycling system by gravity force. If the decanter centrifuge is installed on a low mud tank, then the effluence out from the centrifuge would first flow into the mud tank, and then pumped back to the mud recycling system.
