BALLISTICALLY COMPATIBLE BACKPRESSURE VALVE |
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. |
