For the complex and variable downhole environments of deep and ultra-deep wells, our HS series casing is developed through a special process, endowing the material with high strength and excellent impact toughness. It is widely used in major domestic and international deep and ultra-deep oilfields, such as PetroChina’s Tarim Oilfield and Southwest Oil and Gas Field.
