Laser Slotted Screen Pipe for Oil Well Filtration Uses

Also known as oil sand controls screen pipes, laser cutting well screen pipes, well screen liners, bridge slotted screen cylinders for Heavy Oil production. The slots are laser cutting with precision micron openings, distributed in straight line, parallel, crisscross, bridge, spiral and other patterns. Heavy oil is filled with sand and other sedimentary material. The slotted screen pipe casings are used to filter more than 98 percent of the sand out while the oil well is being pumped. Also applied in water well manufacture.

The oil well screen casings are mainly used for surface casing and protection. It can be produced according to three standards: Chinese standard, German Standard and American Standard

Slotted Liners for Oil Well Screen enjoy the following features:
Robust and cost effective;
Precise slots opening and effective sand control;
High rigidity;
High intensity;
Anti-corrosion;
Uniform distribution.
