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: The eccentric friction increases the friction force of the upper stroke, 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, so that the load of the oil pump increases, the leakage increases, and the pump efficiency decreases.
Centralizer principle
The centralizer is an oil production tool used in oil pumping rig wells. It is a new type of product that can improve the pumping efficiency of the oil well. It adopts a sliding valve automatic opening and closing structure and is connected to the sucker rod. The upward movement of the valve opens the oil passage on the centralizer, and when the sucker rod travels upward, the slide valve moves downward to close the oil passage on the centralizer. Therefore, by lifting the liquid column in sections, the load of the sucker rod and the pump load is reduced in sections, the leakage of the pump 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.
