Product Description

Slotted Casing/Pipes

The slotted liner is mainly used to the water and oil reservation layer without much sand. It's function is to prevent rock bits from dropping into the well bore. The working principle is to allow the certain size and coming fthrough the surface with crude oil but keeping the bigger size sand being outside to form the sand bridge for anti-sand purpose. This type of product is commonly used to sand rock and catbonate reservoir, in particular, suitable for horizontal wells.                                                                                            Slotting Patterns: Line slot pattern, staggered slot pattern, multiple staggered slot pattern.

1. The slotted liner is a robust and cost-effective solution for long completions or low productivity wells
2. We offer straight and keystone slot type in the wide range of slotting patterns to creat the required open area

Plasma Slotted Screen (PSS)

The Structural Characteristics of PSS(1) Specially designed trapezoid slot shape: narrow outside and wide insidea. self - cleaningb. The flow resistance is significantly reduced.c. Good effects of sand control.(2) The slot surface has anti-corrosion electro-chemical treatment by high frequency hardening at 8000HZ and 10000 degree during machining process.a. The slot surface has been generated a 0.1 ~ 0.2mm hardening and anti-corrosion layer.b. High resistance to wearing and corrosion.c. A longer service life than similar products.
