Product Description

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. All the slotted joints are deburred internally, cleaned and drift tested according to API standards. Every slot is visually inspected and cleaned of burr material. All threads and couplings are thoroughly cleaned and lubricated.

1.The pipe joints are in the same body, which is easy to go down, and the inner diameter is large, thus it is easy to process the pipe string configuration.2. It has high strength and allows proper bending, which is suitable for various complex conditions in well. As horizontal well completion string, it plays the function of sand control and support of horizontal wellbore. 3. lLow price, simple construction and low cost of operation.
4. Opening area 2%-6%. 5. Materials: J55, N80, P110. 6. Laser cutting and milling cutter cutting.

Detailed Photos

Slotted liner:The slotted liner is mainly used to the water and oil reservation layer without much sand. It's function is prevent rock bits dropping into the well bore. The working principle is allowing the certain size and coming through the surface with crude oil but keeping the bigger size sand being stopped outside to form sand bridge, and thereby achievement the anti-sand purpose.This type of product is commonly used to sand rock and carbonate reservoir, and especially useful for horizontal wells.

Slotting pattern: line slot pattern, staggered slot pattern, multiple staggered slot pattern.
