The liquid-gas separator uses hydrogen sulfide-resistant materials and liquid-liquid separators for drilling fluids to be manufactured using modern materials using high-quality materials. This equipment can effectively prevent the erosion of harmful gases carried in the drilling fluid and ultimately ensure the use of personnel. And equipment safety. When the construction is carried out, some poisonous and harmful gases carried in the drilling fluid will be carried over. Because of these reasons, the specific gravity and viscosity of the drilling fluid will be greatly deviated from the requirements for drilling; and sometimes the problem is serious. If it is not handled in a timely manner, it will cause well kicking and even blowout accidents. The liquid-gas separator can ensure the smooth progress of the drilling process when used with the electronic ignition device. The design concept of the liquid-gas separator is to separate large amounts of dissolved gas or free air mud, and because these gases expand in volume at atmospheric pressure. Therefore, in the traditional liquid-gas separator located between the choke manifold and the drilling fluid shaker, a pipe line that exclusively discharges gas is connected.
At the drilling site, the frequency of the use of liquid-gas separators and electronic ignition devices is not high, but the importance is unquestionable. Fires are fiercer than tigers, and blowout accidents not only cause major economic and property losses to the country and individuals, but also cause significant pollution to the on-site soil and surrounding environment. Its losses are inestimable.
The GNZYQ1000A series liquid-gas separator is a very good mud gas separator. The gas well drilling fluid enters the separator through the tangent line of the inlet of the separator, and the inner wall falls on a series of specially designed internal baffles, colliding and increasing. The surface area is exposed and flows downward, causing turbulent conditions that separate the gas from the drilling fluid. The free gas is discharged through the gas outlet at the top of the tank. The length of the exhaust pipe is determined and matched by the site, and is led to the safety department. The degassed drilling fluid is discharged into the circulation tank.
 Solar Charged Flare Igniter GN solid control The GNYD electronic ignition device can promptly and accurately ignite the toxic flammable gas emitted from the outlet of the discharge nozzle in the flash of discharge, eliminating the pollution of the gas to the environment and the damage of humans and animals. Guanneng electronic ignition device and solar panels can be configured to use solar energy for post-charge operations to achieve the purpose of energy conservation and environmental protection.
GN solid control will provide you with high-quality liquid-gas separator, as a factory direct sales，we will provide competitive prices, and provide you with satisfactory after-sales technical service for oil field drilling liquid separator and electronic ignition device.

It is well known that oil-based mud is often used for drilling in shale gas drilling projects. The properties of the oil-based mud also determine that the oil-based drill cuttings are often much more difficult to handle than water-based cuttings and the cost is much higher. At this time, customers often choose to focus on oil-based drill cuttings.
Here we briefly introduce the application of the GN cuttings dryer to oil-based drill cuttings.
In the first step, the drill cuttings processed by solid-phase control equipment such as drilling fluid vibrating screens, de-sanders, and drilling fluid desilters are discharged into the cuttings box for unified collection during the drilling process, and the rock is lifted by a lift-swiveling forklift. Chip boxes loaded into the transport truck.
In the second step, according to the preset commuting route, the trucks will use the forklift trucks placed in trucks and transport them to the oil-based drill cuttings drying treatment plant.
In the third step, the oil-based drill cuttings are lifted and lifted by a rotary forklift to raise the cuttings box to the elevated funnel to dump the cuttings. The cuttings enter the elevated funnel and flow to the screw conveyor track, which can be adjusted by spirals. The conveyor controls the flow of cuttings and sends the cuttings evenly into the drill cuttings dryer. After the first treatment, the liquid phase is recovered by the liquid collection tank and stored in a primary treatment liquid collection tank.
In the fourth step, the solid waste is transported to the debris box through the screw conveyor at the bottom of the dryer for subsequent processing. The liquid phase after primary treatment is pumped into the high-speed mud centrifuge for secondary treatment via the screw pump on the collection tank, and the waste discharged from the mud outlet is collected in the cuttings box for treatment, and the liquid discharged from the discharge pipe of the centrifuge is discharged. The phase is a clean, recyclable white oil that is stored in a secondary treatment liquid collection tank.
Finally, the solid phases discharged from the spin dryer and the centrifuge are all stored in special debris boxes. After being collectively collected, they are loaded into trucks by lifting and rotating forklift trucks and transported by trucks to incineration plants, brick factories, cement plants, etc. Waste-producing manufacturers perform the final waste utilization or detoxification treatment.

The test data collected by the barite recovery system produced by our company shows that:
- Barite recycling centrifuge: The rotation speed is about 1800RPM, the “G” value is about 700, the low density separation point: 6 ~ 10μm, and the high density separation point: 4 ~ 10μm.
- Large-capacity centrifuge: The rotation speed is about 1900-2200 RPM, the “G” value is about 800, and the low-density separation point is 5-7 μm (not in the drilling fluid), which is used to exclude the low-density solid phase;
- High-speed centrifuge: The rotation speed is about 2500~3300 RPM, and the “G” value is about 1200~2100. The low-density separation point: 2~5μm is mainly used to remove the low-density content in the un-weighted drilling fluid.
The influence of various parameters of the centrifuge on the operation of the barite recovery system:
- Main engine rotation speed V: It is mainly used to control the size of the particle size of the separated particles. The higher the rotation speed, the smaller the particle size can be separated.
- Auxiliary machine (drum) speed V2: mainly used to control the pushing speed, the higher the speed, when the host speed is constant, due to the difference in speed [X = (V1-V2) / differential speed ratio] reduced ( V1: differential shaft input shaft speed), pushing material speed is reduced, at the same time, due to the reduction of pushing material speed, small particle size particles have settling time, which makes the proportion of small-size particles discharged out of the solid phase increase;
- Liquid supply volume: The amount of liquid supplied by the system determines the speed of the mud cleaning system to treat the drilling fluid, and it also affects the effect of barite recovery: the greater the amount of liquid supplied, the greater the amount of drilling fluid to be treated. The amount of barite that needs to settle during the time increases. When the sedimentation amount exceeds the system discharge amount, a part of the barite does not have enough time to settle, and the liquid phase separated by the centrifuge carries out the centrifuge system, thereby reducing the barite recovery rate. At the same time, as the amount of liquid supplied is increased, more barite is recovered, which may cause system operation failures, in particular, the increase of solid adherence on the screw feeder of the centrifuge, resulting in the balance of the centrifuge drum. Not enough but strong vibration and stuck.
- Meniscus: mainly controls the sediment thickness (liquid pool depth) in the drum of the mud centrifuge and the water content of the solids discharged, and affects the particle size: when the meniscus is completely removed (the height is lowest) The grit thickness (liquid pool depth) is the shallowest, the water content of the solids discharged is the lowest, and the content of small-size particles is the least, but at the same time the pushing load is increased. When the height of the meniscus is the highest, the thickness of the grit sand (the depth of the liquid pool) is the deepest, the water content of the solids discharged is the largest, the content of the small-size particles is the highest, and the pushing load is reduced. Therefore, the depth of the liquid pool must be properly adjusted when the treated drilling fluid contains a large amount of liquid and has a high viscosity.

Drilling mud centrifuge
Clogging a reason: centrifuge work process, due to the pump flow is too large, or suddenly increased suction density of the mud, causing the auxiliary motor trip, resulting in centrifuge blockage.
Blockage two reasons: Centrifuge shutdown, did not follow the rules carefully, there is no flushing, or flushing is not clean, resulting in centrifuge blockage.
If you start the auxiliary motor, if the differential, the drum followed by auxiliary motor rotation, and faster and faster, indicating that the material between the drum and the auger rinse is not complete or even blocked, can’t start the main motor, in this way Centrifuge to overcome blockage; material should be cleaned between drum and auger.
The specific method is: remove the shield, stuck with a pipe clamp Auxiliary motor coupling, to both positive and negative force, not to be brute force to prevent the differential ruined. Can also be injected into the slurry into the pipe, for 12 hours soaking, to help turn the motor coupling.
Open the collection box to clean up:
Per three days, the collection box should be opened for inspection and cleaning. The wear-resistant sleeve, scraper and end scraper on the slag outlet of the mainframe are both fragile and should be used with special care.

Solidification unit is a kind of equipment used for final treatment of drilling cuttings.some time it was called stabilization unit,With the strict environmental protection regulations issued, most rig site has to consider further treat of the drilling cuttings to reduce the waste discharge and recover drilling fluids as much as possible. To make work environment friendly,The further treated drilling cuttings, due to containing of chemicals, cannot be discharged directly.
Normally,the solidifify will need Cement and lime,some special sludge will add chemical like PAM/blinding material/resin,to keep better solid work,and control harmful metal of drill cutting
Based on different sludge’s solidify time with chemical,GN add VFD adjustable motor for sludge/lime/absorber feeding conveyor ,for easier control solidification unit working progress
Treated material will become solid with in10~15 minutes after discharged from unit,the time can be control follow different sludge and chemical
Most important point for using solidification is clean it before push stop,the solids part will stick at internal surface of mixing tank,it will damage the screw and effect further running
Some area moisture degree is too high,we advice make sure lime tank dry enough when running,or it may meet stick things too and effect feeding
GN choose high quality motor for conveyor for longer system service life,for better arrange waste manage plan
