摘要： A jarring tool used to dislodge a stuck tubular string or bottom hole assembly within an underground wellbore. A funnel element is placed underground either within, or as part of, a tubular string. A deformable ball may be seated within the funnel element to block fluid from passing within the tubular string. Hydraulic pressure may build within the tubular string until it exceeds the pressure the ball can withstand. This will cause the ball to deform and be expelled through the funnel element. With no ball to block its flow, fluid will be rapidly released through the funnel element. The rapid release of fluid will cause a powerful jarring or jolting to the tubular string or bottom hole assembly. Deformed balls may be captured in a cartridge chamber installed within the drill string and sized to create turbulent fluid flow within the drill string.
