Centralizer fin is a necessary tool for downhole oil production and plays a very important role in the field of oil drilling and production.

The oilfield centralizer fin is mainly used to centralize the tubing in oil-water deviated wells to prevent the abrasion of tubing and casing wall caused by tubing creep during oil pumping and the cleaning of casing inner wall.

Due to the complexity of well conditions, the following problems often occur in the production process of pumping wells：

1.  Eccentric wear of sucker rod: eccentric wear of sucker rod will reduce the production rate of pumping wells and increase the production cost.

2.  Low pump efficiency: eccentric wear increases the load of the pumping unit due to the increased friction on the up stroke, which increases the energy consumption. The stroke loss is large and the pump efficiency is low.

3.  With the increase of the water content of the liquid, the specific gravity of the liquid will increase, so that the load of the oil pump will increase and leak, and the pump efficiency will increase and decrease.

The appearance of centralizer has properly solved all the above problems.

Centralizer is mainly composed of body/rotary centralizer, with the following characteristics:

1. The oilfield centralizer fin ensures that the tubing is centered and reduces eccentric wear. It is essential to prevent cable damage and helps to solve the problem of the location of inclined or vertical well tubing.

2. Simple structure, flexible rotation, low friction and good centralizing effect.

3.  It is used at both ends of the packer and is convenient to apply. It can reduce the friction damage of the well wall to the packer element, extend the service life of the packer and reduce the relative cost.
