Petroleum drilling fluid mud agitator seller

⋅ Leave a Comment

The mud agitator is widely used in the ground tank of the drilling fluid. The mechanical mud agitator is made of the drive motor, gear reducer, transmission box output shaft and impeller ect.The appropriate mud agitator can keep all the solid phase particles uniform, if  the shearing action is proper, the performance of the drilling fluid system is all the same and can save power.

  

The principle of operation

The impeller can stengthen the stirring effect by making vortex of the drilling fluid. The tray installed between the leaf blades can prevent the deposition of the solid particles when the machine stopped, thereby, to reduce the moment of resistance inflicted by the sediment to the impellers when restart the equipment, therefore, to avoid burnout of the machine.

The structure of the mud agitator

The transmission mechanism

The transmission mechanism are mainly made of motor, reducer device, coupling and the mixer shaft, there are a few drilling fluid mud agitators in the solid control equipment. The rotating mechanism of the turbine and the worm is simple, the strong reliability, it is the most popular in the drilling fluid, now the foreign all use the worm and gear to rotate directly.

Impellers

The impeller is the part of rotation, the structure of the impeller determines the function of the impeller, the sharps of the different liquid storage tanks are different, we select the different impellers according to the experiences and customs. The reasonable method is according to the mixing purpose and the formation of flow state to select .

The mixer shaft

The mixer shaft is the structure of lifting, in the process of the drilling fluid, the agitator can’t stop. There are some causes in the practical work, so usually it can’t reach the
Requirement. After the agitator stoped, because the tank has desilting, the serous tables are buried in the desilting, it is very difficult to start. The blades are often breaked and the motor is often burning loss.

Petroleum drilling mud agitator VS mud gun

⋅ Leave a Comment

Drilling fluid gun belongs to the water conservancy agitator equipment, its function is rely on high speed fluid which is produced from the gun nozzle, impacting the solid phase which in drilling fluid bottom storage tank and keep it suspension. After the agitator stop a period of time, the depositional solid phase bury the impellers, it is needed to restart, drilling fluid gun can eliminate a part of resistance distance when the agitator start, it can provide the reasonable guarantee for regular work of agiatator.

The mud agitator is composed by explosion-proof electric machine, reducer,engine base and impeller components. The electric machine ,reducer and impeller shaft are connected with each other by solid couplings. 4 leaf blades were welded on each impeller.

Operarting Principles: The impeller can stengthen the stirring effect by making vortex of the drilling fluid. The tray installed between the leaf blades can prevent the deposition of the solid particles when the machine stopped, thereby, to reduce the moment of resistance inflicted by the sediment to the impellers when restart the equipment, therefore, to avoid burnout of the machine.

   

The structure of drilling fluid gun

According the structure of drilling fluid gun, it is divided into stationary type and rotation type.

1 The stationary type drilling fluid gun is similar with water conservancy agitator which the tank has nozzles, but the drilling fluid gun is installed on the two diagonal which is from 200meter to the bottom tank, the nozzle direction is parallel the longitudinal tank wall of circulation tank.

2 The rotation type drilling fluid gun is divided into hand regulation and autorotation. The hand regulation agitator has two hinges, it is made of access tubes, shell, spray gun and the replaceable nozzle

The differences

1 The cost of drilling fluid gun is lower than mechanical agitator.

2 In the premise of meet the requirements of pump power can use the drilling pumps.

3 The flow can concentrate in a location to decrease or eliminate the dead zone.

4 The weight is lighter than mechanical agitator.

5 It can improve the rate of shearing.

Shortcomings

1 If use along the drilling fluid system stir, it need a lot of drilling fluid guns, the cost of pumps and pipes is big.

3 The nozzle is abraded and let to high speed flow, it needs greater power, if the nozzle is not replaced in time, it may led to motor overload.

4 If solid phase have already precipitate, drilling fluid gun directly shot to the sediment, the sediment is maybe blocking the pump, conical shield or centrifugal.

The spray gun with the nozzles, rely on the two hinges, it can spurt any direction in the two perpendicular planes inside. The automatic rotary drilling fluid gun is made of input pipes, body gun, cross fitting, the two bends with nipples, replacement nozzle and two coat nots.

 The use of drilling fluid gun has a certain limitation, drilling fluid gun is auxiliary tool of mechanical mixing plant device, the mud gun can dispose the solid phase suspension which is didn’t disposed by mechanical agitator. According the research date, the depth of useful effect is only 1.5-2.7m, it is related with the drilling fluid density, viscosity and the speed nozzle.

Well drilling mud Chinese shale shaker screen

⋅ Leave a Comment

The importance of the screen

The combination property of the drilling fluid shale shaker reflect the sieve size is fine, using life is long and the throughput is big, this conditions are related to the structure and performance of the screen. The screen is a important part of screening task, it is the consumables in drilling fluid, the size of the hole determines the size of the solid phase particles are removed by the shale shaker. Because drilling fluid have corrosive, abrasive resistance and the high temperature,

The specification of the screen

The specification of the screen determines the sieve size, the sieve size is the size of the sieve pore which the particles can pass. Because the oilfield and the related industries learn from the foreign stander, so use the mesh representative the size of the sieve pores, it is said that the number of the sieve pores in one inch width.

For different drilling mud equipments manufacturer will hold their own model

In order to remove the smaller particles in drilling fluid, the material of the screen is the stainless steel wires of the heat treatment, the material of the ancillary shoring structure is steel plate, galvanized sheet, plastic board and ect.

shale shakers. Different type shale shaker will hold different features and superiority.

To develop both precise and accurate process control, DC conducted a battery of tests. These tests included; cure tests by varying time and temperature; bonding strength tests by testing the tensile strength of the cure screens through destructive testing; and chemical exposure tests by immersing a series of screens in chemicals characteristic of the oil & gas industry.

Mud gas separator is a special equipment of gas cut drilling fluid, it belongs to the ordinary pressure, it is the degassing theory of ordinary pressure, but it is the primary degassing equipment of disposed the gas cutting drilling fluid, the main distinguish with vacuum degasser is; it can remove the big bubbles which the diameter is bigger than 3mm. The big bubbles are refers to the swelling gas of the most drilling fluid is full of the well, their diameter are about 3-25mm.  This big bubbles can cause well kick, even erupt the surface of turntable. The gas liquid separator is mainly depend on the effect of gravity collision to realize the liquid and gas separate, the vacuum degasser use the principle of vacuum, flocculated flow and centrifuge, the quality of processing gas of vacuum degasser is less than the liquid gas separator, but it remove the gas more thoroughly. Usually the gas is processed by the liquid gas separator also have small bubbles, after through the shale shaker, it needs enter into the vacuum degasser to conventional gas.


        


The types of liquid gas separator


1 Cover type


The bottom of vacuum degasser is closed, drilling fluid through a U type pipes to return the circulation tank. The depth of drilling fluid in the degassing tank, it can control by the depth of the U type pipes.


2 Open bottom type


The separator have not bottom, the lower parts dive into the drilling fluid, the liquid level in the tank depends on the drive depth of bottom to control, this type of separator is called the “poor children” in foreign, it explains the simplification.

The most simple and reasonable liquid gas separator is the cover types. The open bottom types is take second place, because the depth of drilling fluid is limited to the liquid level depth in circulation tank. The working pressure of liquid gas separator is equal to the frictional drag of when the free gas discharge tubes discharge.

The use of hydrocyclone DC mud system

      
    
		 ⋅ Leave a Comment      

    

  

  
  
	
		
Hydrocyclone is a kind of mechanical separation equipment with simple and easy to maintain. Separation is realized by the admission energy change into the interior barrel centrifugal force. The centrifugal force act on drilling fluid, make drilling cuttings and other solid phase separated, this is follow Joe hicks’s law. Because the drilling cutting is too fine in some strata drilling, drilling fluid shale shaker can’t remove the drilling cuttings, so must use hydrocyclone remove the most of particles. Drilling fluid shale shaker avoid the big particles enter into the hydrocyclone and led to blocking, protect the hydrocyclone.


The best separate effect of hydrocyclone is the least liquid loss, obtain the maximum drilling fluid solid phase to discharge. The small and light particles are discharged through the overflow month. The biggest effect to the performance of hydrocyclong is the diameter, cone Angle, the diameter of bottom month, the pressure of admission, the model form viscosity of admission.




Advantages


1 The device is compact, the structure is simple, the price is cheap, have no movement     parts


2 The throughput is big, the range of separation is large.


3 Adjustment and operation is easy, and it is easy to maintain.


4 The ability of separation is great, in some cases, can obtain the overflow of more fine and the higher of separative efficiency.


The shortcomings of hydrocyclone


1 The power consumption is big


2 When the viscosity of the pulp, the density of solid phase and the composition of particles size are changed, the separation particle size and separation effect is changes.


3 The working condition of desander pump is greatly influenced the hydrocyclone.


4 It can’t carry out super fine separation. It can’t disposed flocculating substance
