The slotted pipes or liners using in oil exploration can prevent 99% sand, decrease 80% of oil well heavy repair and increase the oil well's strength, integrality and stability of keeping off sand. Meanwhile, the laser incision can make very small cuts with smooth surface and high precision. Although its structure is simple, it is very effective. It has small cuts of 0.10-0.5 mm in the tube wall.
The slotted pipe works by allowing certain particle size coming through the surface with crude oil while keeping the bigger size sand staying outside, and thereby the anti-sand purpose is achieved.
Line slot pattern, staggered slot pattern, multiple staggered slot pattern.
Slotted liner screen has several unique advantages when compared with using of perforated pipes.
The slotted liner is a robust and cost-effective solution for long completions or low productivity wells.
We offer straight and key stone slot in a wide range of slotting patters to satisfy the required open area.
High rigidity resisting scrape and abrasion, high intensity, anti-corrosion and even distribution.
