Concentric casing system with wings
Drilling through formations with loose, unconsolidated material always comes with problems such as the bore hole caving in or collapsing. How to avoid these problems? With years of field practice and research, we have developed concentric casing system with wings applicable for rock formation with silt, and or small sized pebbles. With its simple structure, convenient operation and reliable performance, the concentric casing system with wings can advance the casing easily for depth within 30 meters. It is retrievable and it has long lifetime.
