The rigid centralizer is an essential tool for downhole oil production and plays a very important role in the field of oil drilling and production. What is the function of the rigid centralizer?

Centralizer use

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

1. Eccentric wear of the sucker rod: After the eccentric wear of the sucker rod, the production rate of the pumping well will be reduced and the production cost will be increased;

2. Low pump efficiency: due to eccentric wear, the friction force of the upper stroke is increased, which increases the load of the pumping unit, increases the energy consumption, the stroke loss is large, and the 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 and causes leakage, and increases the pump efficiency.

The emergence of rigid centralizers just rightly solves all of the above problems. The principle of rigid centralizer: Rigid centralizer is an oil production tool used in oil field pumping rig wells. It is a new type of product that can improve the pumping efficiency of oil wells. When the oil rod goes down, the slide valve goes up to open the oil passage on the centralizer, and when the sucker rod goes up, the slide valve goes down to close the oil passage on the centralizer. Therefore, by lifting the liquid column in sections, the load on the sucker rod and the pump is reduced in sections, the pump leakage is reduced, the elastic elongation deformation of the sucker rod is reduced, and the stroke loss is reduced, thereby improving the effective stroke of the sucking pump and increasing the filling of the pump barrel. volume and improve pump efficiency.
