Gas buster can be also called as poor boy degasser, mud gas separator.

GN standard gas buster is ZYQ1000, with 39.4 inch diameter, 1400GPM treating capacity, dimension is 2000 mm diameter x 5860mm height, weight is 2000kgs. Fluids intet pipe diameter is 4inch, fluids outlet pipe diameter is 8 inch, gas discharge pipe diameter is 8inch, we can made customized pipe dia if the required qty is large.

Gas buster is normally used together flare ignitor, after the dangerous gas is separated out, they use a flare ignition device to burn it.

 

GN has 6 units Vacu-Flo degassers in stock, welcome to inquiry us.

How to maintain vacuum degasser?

1.The top cap of degassing vacuum cylinder should be cleaned weekly to eliminate gas channel plugged by any wastes.

2. Cut off the power after use.

4. At operation, check the vacuum gauge frequently.

5. Drain off the water after use each time.

6. Main shaft bearing should be added sodium base grease (abut 250~300ml every other month with a lubricant injector).

7. To the vacuum pump working and lubricating condition of the bearing should be checked frequently.

 

There are many shale shaker manufacturers in the world, mainly from USA, China, Europe, New Zealand. Here is a list of world’s top brand shale shaker.

1 Derrick linear motion shale shaker

2 NOV Brandt King cobra shale shaker

3 MI-SWACO Mongoose PT shale shaker

4 GN solids control linear motion shale shaker & BEM shale shaker

5 DFE shale shaker

6 Kem-tron shale shaker

…and more

GN solids control has GNZS703 & GNZS853 shale shaker in stock in one month.

 

Weighting materials are a high-specific gravity and finely divided solid material used to increase the density of a drilling fluid.  How to add weighting materials to the drilling fluids?

In most oil & gas drilling solids control system, there are weighting tank, which has a mud hopper and mixing pump, the operator add the additives from the top of the venturi hopper, the mixing pump transferred the drilling fluids through the cross under the hopper, under the working of pressure, the power material are added to the drilling fluids. It will be mixed by mud agitator installed on the tank. Sometimes shear pump will be used instead of centrifugal pump.

GN designed 1000gpm mud cleaning system including the following equipments:

2sets of GNZS703 shale shaker or GNPS703 shale shaker, 1 set of GNZJ703 mud cleaner, 2 units of mud agitator, 1 mud hopper, 3 sets of centrifugal pumps, 3 ea lights, 1ea mud tank 14.5meters length. This is standard design, we can revise it according to client’s particular requirement.

This 1000gpm mud cleaning system can be used for various applications, like HDD, CBM, even small rigs for oilfield. Welcome to contact GN for more details.

Cutting dryer/vertical cutting dryer is widely used for drilling cuttings management in the oilfield. Lubrication is important for cutting dryer’s maintenance. Manufacture will provide detailed lubrication diagram with the machine. Motor bearings are grease lubricated, the other bearings are all oil lubricated.

 The oil should be changed every 1600 hours of operation or every three months, whichever occurs first. To change oil, drain oil from the gear unit and drain pot. Gear unit plugs are located under the inside sheave. Oil can be drained from the drain pot by disconnecting the suction line at its union located left of the filter and above the pressure switch.

GNCD930 vertical cutting dryer user manual provide more info about the lubrication diagram.

GN produced decanter centrifuge for drilling fluids, bowl assy is the main body of the decanter centrifuge. Bowl assy including collection box, bowl, inner tube, screw propeller, gear box, hydraulic coupler, pulleys, bearings, etc.

Bowl is the most important component, in includes taper piece and straight piece, previous production procedure is to make them separately and connected by bolts, GN produced centrifuge bowl is one piece bowl, the connection is welding, such centrifuge bowl is more steadily in performance and working time.

There are mainly 2 type degasser used in oilfield, vacuum degasser and poor boy degasser.

Vacuum degasser is used in drilling solids control system to remove the gas such as methane, H₂S and CO₂ from the gas-cut mud, there are horizontal vacuum degasser, vertical vacuum degasser and atmospheric degasser.

Poor boy degasser is well control equipments, it is used to separate dangerous gas, and the vacuum degasser is used only when we need more effective and more efficient results.

GN designed GNLW363 decanter centrifuge with a two-stage planetary reducing gear box, also called differential.

There is internal gear on the shell. Shell rotate with the drum, and then left pulley drive 1-stage sun gear on the input shaft to rotate, at this time, 1-stage sun gear gear into inner gear through 1-stage planet gear, thus 1-stage revolving arm rotational speed is formed by rotational speed of shell and input axle, and this rotational speed was outputted to 2-stage through 2-stage sun gear. The transmission principle of the two stages are the same, at last, propeller begin to rotate driven by output shaft. Differential is the most complex and most important part of decanter centrifuge.

 

GN designed CD930 vertical cutting dryer is applied to drilling waste management system in the rig site. Basket is the main wear parts for cutting dryer, the picture below is cutting dryer basket.

Screen opening can be choose by various field test result. The basket material is stainless steel,inside the basket, there are screen, rotor wheel, they are the main components of cutting dryer.
