Latest Patents

Yongcun Feng holds a patent for a "Multi-stage fracturing sliding sleeve." This invention comprises a fracturing pipe, a shear slip device, a fracturing sleeve, a ball seat support, a first sliding sleeve, and a limiting sleeve. The fracturing sleeve effectively seals fracturing ports, while the ball seat support and the fracturing pipe are connected through at least one first shear pin. A first spring is arranged between the first sliding sleeve and the limiting sleeve, and a second sliding sleeve is positioned below a multi-segment ball seat, connecting with the first sliding sleeve. The design includes a downward-facing annular shoulder on the outer wall of the first sliding sleeve and an upward-facing annular shoulder on the inner wall of the limiting ring. The first spring is located between these shoulders, and the upper end face of the limiting ring restricts the axial travel of the first sliding sleeve. This innovative design aims to improve the efficiency and effectiveness of multi-stage fracturing operations.
