The main function of petroleum screen pipes is sand control.The steel grades and types of screen pipes adopted vary dependingon the different geological environments (lithologies) of oil wells.The characteristics of petroleum screen pipes are as follows:High strength and not easy to deform.The verticality of the slotted edges is good, the cut edges are smooth, free of burrs, and the slots are uniform.

Its advantages are more obvious when used in deviated wells and horizontal wells.

The overall anti corrosion treatment is carried out to improvethe anti - corrosion and wear resistance of the screen pipe.

It is suitable for sand control in sand - producing wells where the sand - producing particle size is greater than 0.3mm.
