    摘要: A backpressure valve. The backpressure valve may be configured to maintain a substantially controlled pressure in bottom hole assembly while simultaneously being compatible with a pressure pulse tool downhole thereof. The backpressure valve includes pressure generating capacity below its internal valve assembly so as to avoid the tendency of the assembly to throttle open and closed. Furthermore, the pressure generation is achieved in a manner avoiding cavitation. As a result, once the backpressure valve is opened, the pressure pulse tool is able to reliably communicate with surface equipment at the oilfield.

    摘要: A backpressure valve. The backpressure valve may be configured to maintain a substantially controlled pressure in coiled tubing uphole thereof while simultaneously being compatible with a ballistically actuated tool downhole thereof. The valve may include a housing with an uphole chamber in alignment with the coiled tubing and downhole chamber in alignment with the ballistically actuated tool. A gate mechanism disposed between the uphole and downhole chambers may thus be employed to receive a ballistic actuator from the uphole chamber for dispensing into the downhole chamber without sacrifice to pressure control within the coiled tubing.
