Analyze the function and application of centralizer

The centralizer is connected with the sucker rod,and the sucker rod centralizer plays a good role in correction,which solves the serious problem of eccentric wear of oil Wells in the oilfield.At the same time,it can also serve as a wax scraper,which can expand the use of pipes,rods and pumps.Life expectancy and extended pump inspection cycles effectively increase well production and reduce production costs.
Functions and characteristics of casing centralizer:

1)The casing centralizer is basically in a folded state when it is put into the well,and its initial outside diameter is small,which reduces the risk of stuck well.

2)Prohibit downhole pressure opening.The opening pressure is only related to the differential pressure between the annulus inside and outside the wellbore.Hydraulic shear pin is opened underground,high reliability.

3)The elastic centralizer is made of spring steel with large deformation,large expansion diameter and large support force after expansion.

4)After opening,it has locking function,can stop before and after in time,and can adapt to different degrees of reaming.
