    摘要: A multiple activation-device launching system for a cementing head comprises a launcher body and at least one launching chamber that are sized to receive one or more activation devices therein. The activation devices are launched into the principal process-fluid stream inside the cementing head, and may be darts, balls, bombs, canisters and combinations thereof. The launching chambers are in fluid communication with an external power source for launching the activation device into the principal process-fluid stream.

    摘要: A hydraulic wiper plug launcher (8) includes a coupler (22) releasably mounted on the upper end of a well casing (9). The outer coupler body (10) has an inner shoulder (49) and an open ended plug container (12) has a stack of wiper plugs (16) compressed therein. The upper end portion of container (12) forms a fluid chamber (S2) above the uppermost wiper plug (16). A precise predetermined volume of fluid is supplied to fluid chamber (S2) for expelling the plugs (16) in a controlled sequence. The length of the fluid chamber (S2) in container (12) increases an amount equal to the length of the wiper plug (16) pushed or expelled from the open lower end of the container (12).
