Exhibition is the best purchase, sales and propaganda platform of a company, a manufacturer.

On September 17, 2012, Tangshan Dachuan Machinery co.,ltd. Took part in the offshore, oil and gas technology, equipment exhibition of Dong ying. There were a lot of companies in the exhibition, for example, Shengli oil field petroleum equipment co.,ltd. Rong li petro leum machinery and Jin sheng yuan solid control company and so on . The bigger exhibition hall is Jin sheng yuan solid control company. There is a shale shaker, a mud cleaner and several hydrocyclones in the exhibition hall.

   

The salesman of the company and I talked about one hour, I understood the main marketings and the sales model of the company, I studied the sales methods and the keys with the excellent salesman, and exchanged the sales experiences and realized.

Because the time is short, so our company can’t order the exhibition hall, but according our studies and observation, we got a lot of valuable knowledge and experiences, and meet a lot of foreign friends, there are Mark joony, Duanie A. priestley and Allen B.Kilback and so on.

  

DuanieA.Prestley was very interested with our centrifugal, and detailed understand the centrifugal of DC manufacturer with the technical engineer, he hoped establish business relations with us. And we leave the contact information each other.

Form the exhibition, I learned that the main of sales are daring to open, and I hope according about 6 months to exercise, the next time,  Beijing exhibition, my sales model and the spoken language are improve.

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.

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.

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 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.

Advantages

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.

To my surprise, on the morning September 3, I went to work, I have no attention to open my email, I found a inquiry email from Italy solid control company, he said they saw our products on alibaba, they were very interesting with our company, they want the inquiry with shale shaker, I excited to shout” I have inquiry”, this is the first inquiry from my work within the three month. I had very excited, after I send a price list to him, of course this is my first order, so the price is lower compared with the same industry of other companies, the client was satisfied with my inquiry, then he sent a detailed content with shale shaker, the main content is; they want a shale shaker mating with 3000 meters well, let us gave a suggestion for him, then the detailed content was sent to our technology engineer, the engineer patient and careful design, at last fished a reasonable and reliable scheme. On September 5, we sent the scheme to the Italy client, the client thought that there are some parts were didn’t matching the link way and terrain. Then we received the need and improved the scheme, at last the client was very satisfied with our service and scheme. He hope we can established business relations each other, we also hope we can have business communication.

This order is succeed, it give me confidence and patience, I believe that efforts will be fruitful.

Now, we have already manufacture the shale shakers, this is the process of manufacture which I took the pictures in the manufacturing shop.

         

TangShan Dachuan Mechanical Equipment Co., Ltd. is a company focuses on the production, sales and after-sales maintenance service of mud cleaning  equipment of petroleum drilling (not excavation). The main products are mud vibrating screen, vacuum degasser, desander, disilter, mud cleaner, mud gas seperator, mud agitator, desander pump, shear pump, centrifugal, flare lgnition device, mix funnel, jet mud mixer, mud tank, water tank, diesel tank, etc.


 


  

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.
