Mud Tank and Corollary Solids Control Equipment

In drilling waste management, mud tank is an important oil drilling mud equipment.

mud tank

As is an indispensable part of oil drilling fluid solids control system, mud tank has been improved a lot in recent years. According to the tank bottom shape, mud tank is divided into square mud tank and conical tank. Tank body adopts flat conical structure or corrugated structure, welding steel group steel and type. Tank surface and the skid resistance steel plate and strip corridor slip board, tank surface railings with square steel tube making, for barrier free folding structure, firm inserting.

 

 

The surface of mud tank is equipped with water to cleaning tank pipeline and equipment, tank surface mesh using zinc dipping treatment. Tank ladder adopts channel steel as the main body, with anti slip strip plate to do the pedal, bilateral guardrail is provided with a safety hook. Oil drilling mud tank construction standard sand, rain proof shelter, tank is provided with heat insulation pipeline.

Corollary solids control equipment for mud tank are shale shaker, vacuum degasser, desander, desilter, all-in-one machine, mud gas separator, mud agitator, sand pump, shear pump, decanting  centrifuge, flare ignition device, jet mud mixer, the mud gun etc.

Jet mud mixer for drilling mud system

Jet mud mixer is widely used in the solid control system, the device main function is to changing the density, viscosity,water lose and another of the drilling fluid.

When used with shear pump, its function will become more better.With advantages of safety, reliable, easy to moving and handling, Brightway Solids Control Series jet mud mixer is an ideal choice for you in the oil drilling solids control system.

 

 

Jet Mud Mixer is a corresponding equipment of solids control system, which meet the needs of solids control drilling fluid weighting and compounding in case of different drilling depth. It is combined with a centrifugal pump(or many sets) and a Jet mixing hopper(or many sets), connected by manifold and valve then installed on a base. Aggravated hopper and sand pump can be connected by manifold and valve, or installed separately.

Jet mud mixer is the equipment match with drilling solids control equipment, usually used to configurate and increase the proportion of drilling fluid, change density, viscosity, water lose etc. It has a more excellent effect if  matched with shear pump, and also can be designed to double jet mud mixer as clients’requirements.

shale shaker

Jet mud mixer is used in solids control system,in this system it is combined with other solids control equipments,such as shale shaker, desander, desilter, mud cleaner, vacuum degasser,decanter centrifuge, submersible slurry pump,shear pump,centrifugal pump,mud agitator, mud gun, shaker screen,jet mud mixer,mud tank,etc.

4 Fixing shaker screen box during transportation: In order to prevent any damage during transportation, please remember: the locking yoke should be tightly locked in transportation, making sure that there is no relative movement between screen box and pedestal. The locking yoke should be unlocked before its starting, otherwise, the machine will be seriously damaged! 5 The 5maintenance on sieving medium:shale shaker

 

The shaker screen should be medium should be cleaned with clean water at the same time. The sieving medium and its stand should be cleaned by water (in summer) or vapor (in winter) at least every shift.

shaker screen

There should not be too much sediment on the sieving medium and its stand, especially when the viscosity or density is high or the screen mesh is thinner than 60. Otherwise sedimenothesieving medium will block the meshes when dried, and the efficiency will be greatly impact its later operation, causing unnecessary escapes of slurry.

When installing, the right end (looking from the sand discharging mouth) should be fixed firstly and make sure that the outside of the screen cloth has tightly pressed on the stopper beneath the bolt hole. The middle bolt among the three ones should be solidly fixed for smoothly and evenly stretched. The bolts are exclusive. And special attention should be paid to on the work site lest it be lost.

Shale shaker is a important part of solids control system, which is used widely in oil and gas drilling works. How to install and debug is a very important part.

 

 

1 The shaker screen can be used alone or have two or more combined in which slurry influx pipe manifolds can be made according to the users’ requirements.

 

2 The installation and replace of the screen cloth: Screen cloth is an expensive wearing part for shaker screenthis equipment, the quality of its installation will directly influence its service life. A bolt stretching device is adopted to fix the screen cloth.

3 The regulating of the screen box’s dip angle: When slurry discharging quantity is too much or escaping because of a higher viscosity, the screen box’s dip angle should be regulated. The best dip angle is that one preventing slurring from escaping. The screen box’s dip angle of the facility can be discretionarily regulated by the values including -1°, 0°, 1°, 2°, 3°, 4°, 5°. When adjusting, the oil return valve of the hand centrifugal pump should be screwed down firstly and tightly. At the same time, lightly press the manual rocker until the lifting slide bushing will be going up a little. By this step, have the pin drawn off with pressurizing finished manually. The movement of the hydraulic cylinder will change screen box’s dip angle. When the regulation finishes, the facility will not resume its work until the bolt pin is inserted with oil return valve unscrewed. While the screen is in its operation, the slurry should cover 3/4 of the screen cloth. If the covered area is not up to the standard, it shows that the screen mesh is too thick. And to improve its purifying result the screen with thin mesh must be replaced.
