Do you know the purpose and principle of centralizer?

I.Introduction of centralizer

Centralizer is a kind of cementing tool,which is simple to manufacture,beautiful in structure,durable and strong in centralizer.It overcomes the shortcoming that the original welding centralizer is easy to dissolder and is a kind of centralizer to ensure the quality of drilling cementing.There are many kinds of centralizers,including roller type,slider type,automatic reversing type,etc.
Two,the use of centralizer

Due to the complexity of the well condition,the following problems often occur in the production process of the pumping well.

1.Sucker rod bias wear:after rod bias wear,the production time rate of the pumping well will decrease and the production cost will increase.

2.Low pump efficiency:due to eccentric wear,the load of pumping unit increases,energy consumption increases,stroke loss is large,and pump efficiency is low;

3.As the water content of the effluent increases,the specific gravity of the effluent increases,which increases the load of the oil pump,increases the leakage,and reduces the efficiency of the pump.

Three,the principle of righting

Centralizer is a kind of oil production tool used in oil field pumping well.It is a new product which can improve the pump efficiency.It adopts the automatic opening and closing structure of the slide valve connected with the sucker rod.
