发明名称 VIBRATION TOOL
摘要 Various implementations described herein are directed to a vibration tool, e.g., for use in drilling or other downhole operations. In one implementation, the vibration tool may include a housing having a bore extending therethrough. The vibration tool may also include a piston subassembly positioned inside the bore, where the piston subassembly is configured to oscillate when fluid flow inside the piston subassembly exceeds a predetermined flow rate. The vibration tool may further include a valve mechanism positioned around the piston subassembly, where the valve mechanism is configured to restrict fluid to flow inside the piston subassembly when the valve mechanism is in a closed state and configured to allow the fluid to flow from the piston subassembly to the bore when the valve mechanism is in an open state.

主权项 1. A vibration tool, comprising: a housing having a bore extending therethrough; a piston subassembly positioned inside the bore, the piston subassembly configured to oscillate when fluid flow inside the piston subassembly exceeds a predetermined flow rate; and a valve mechanism positioned at least partially around the piston subassembly, wherein the valve mechanism is configured to restrict fluid to flow inside the piston subassembly when the valve mechanism is in a closed state and configured to allow the fluid to flow from the piston subassembly to the bore when the valve mechanism is in an open state.
