Centralizer is a kind of cementing tool,which is simple to manufacture,beautiful in structure,durable and strong in centralizer.It overcomes the shortcoming of the original welding centralizer which is easy to dissolder and is a kind of centralizer which can guarantee the quality of drilling cementing.There are many kinds of centralizers,including roller type,slider type,automatic reversing type,etc.The centralizers produced by our company include tubing centralizers,sucker rod centralizers,casing centralizers,special tubing centralizers,all metal sucker rod centralizers and nylon centralizers.Centralizers of different structures and materials are suitable for different types of deviant wear Wells.The key technique of using centralizer to prevent eccentric wear is centralizer's installation position,spacing and quantity.
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.
