Latest Patents
Xiaoping He's latest patents include innovative designs for drill string shutoff valves. The first patent describes a valve assembly that connects into a drill string, allowing for the opening and closing of at least one inner passage. This valve assembly features an annular valve that moves between open and closed positions in response to downward fluid pressure from the surface. Additionally, it includes an inner valve assembly that acts as a two-way valve, which is actuated by pressure pulses from the surface. This design can be utilized within coiled tubing, enhancing operational flexibility.
The second patent also focuses on a drill string shutoff valve, which connects into a drill string to control the passage within it. This assembly includes an inner valve member that opens and closes the inner passage based on axial movement of the drill string. When the drill string is lifted, the upper portion moves upward, bringing the valve member along with it, while the valve sleeve remains stationary, thus opening the valve. This innovative design can also incorporate an annular valve assembly for additional control.
