    摘要: A rotatable flanged component is adapted for assembly into a flow line of a high-pressure fluid transportation system. The rotatable flanged component comprises a body and a conduit. The body has at least two ends. The conduit extends between the ends. The rotatable component also has a flange and a union face at each of the ends. The flanges and union faces are adapted to provide a flange union between the component and other flowline components at each the body end. At least one of the flanges is a rotatable flange. The rotatable flange has a central opening and a plurality of holes. The holes are adapted to accommodate threaded connectors for loading the flange with an axial force. The flange is mounted on the body end through the central opening for rotation and for transmission of the axial force to the body end.

    摘要: Missile flow lines are incorporated into frac manifolds, especially trailered or skidded frac manifolds. The missiles manifold the discharge from a plurality of pumps and comprise at least two junction fittings joined by spooled pipe. The junction fittings comprise a body having a primary bore and at least two feed bores. The intersections of the feed bores with the primary bore are offset axially from each other along the primary bore. The junction fittings are joined by flange unions to at least one spooled pipe such a that the junction fittings and spooled pipe form a conduit including the primary bores. A discharge line from a pump may be joined to each feed union face of the junction fittings by a flange union. Thus, the discharge from the pumps may be manifolded into the conduit.

    摘要: A gas lift system for oil and gas wells has a gas pump. The gas pump comprises production tubing, a chamber, a dip tube, check valves, a gas supply line and control valve, a gas vent line and control valve, and a fluid control line. Liquid is pumped to the surface by allowing it to collect in the chamber and then forcing it out of the chamber with high-pressure gas. The gas supply and vent valves preferably are controlled by a single pressure control line. The system preferably included retrievable valves that may be installed through the production tubing to provide a life-of-the-well gas lift system.

    摘要: A method of unloading and producing liquids from a well uses a plurality of gas injection valves installed on a production tubing. The injection valves are controlled by pressure signals transmitted through a single fluid control line. A first pressure signal is applied to the control line to open the plurality of injection valves. Gas is pumped into the annulus at an injection pressure until a first pressure drop occurs in the injection pressure, the first pressure drop being indicative of gas flowing through a first, upper one of the injection valves. Pumping of gas is continued until a second pressure drop occurs in the injection pressure, the second pressure drop being indicative of gas flowing through a second, lower one of the injection valves. A second, lower pressure signal then is applied to close the first injection valve while leaving the second injection valve open.
