Due to the complexity of the well conditions, the following problems often occur during the production process of pumping wells.
1. Eccentric wear of sucker rods: After eccentric wear of sucker rods occurs, it will reduce the production time of the pumping well and increase production costs;
2. Low pump efficiency: Due to eccentric wear, the friction force on the upper stroke increases, which increases the load on the pumping unit and energy consumption, resulting in large stroke loss and low pump efficiency;
3. As the water content of the liquid increases, the specific gravity of the liquid increases, which increases the load of the oil pump and causes leakage, leading to a decrease in pump efficiency.
The appearance of the centralizer perfectly solves all the above problems.
