Perforated casing pipes are widely used in both oil & Các ứng dụng giếng khí và nước. They play a crucial role in enabling efficient fluid flow, protecting the wellbore, and ensuring the overall longevity of the well. The pipe’s perforations (holes) allow for controlled inflow or outflow of fluids while preventing the collapse of the wellbore, which can be caused by external pressures. This article provides a comprehensive look at Perforated Casing Pipes, including their specifications, nguyên vật liệu, các loại, tính chất cơ học, and applications in the oil, khí đốt, and water well industries.
