Abstract:
A hydraulic pulse valve for use in downhole tools includes a split ring seal to limit the fluid flow available to shift a poppet in the valve from an open position to a closed position. The split ring seal provides relatively long and repeatable pressure pulses, which improve the effectiveness of the hydraulic pulse valve for borehole applications.
