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： Pivot valves have a valve seat and a valve closure mounted for pivoting movement through a closure chamber in a passage. The pivot valves may be selectively set in a check mode and an open mode. Flapper valves have a hydrofoil extending from a flapper. Valve assemblies comprise the pivot valves and flapper valves and have an open condition, a check condition, and a shut-off condition.

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： Flowline junction fittings are assembled to missiles of frac manifolds. The fittings have a body with a primary bore, at least four secondary bores, and a tertiary bore. The bores extend from union faces adapted for connection to flowline components by a flange union. The tertiary bore intersects with the primary bore at an angle of approximately 90°. Goat head fittings are assembled to well heads. The goat heads have a body with a primary bore and at least four secondary bores. The bores extend from union faces adapted for connection to flowline components by a flange union. The intersections between the secondary bores and the primary bore have an interior angle of substantially less than 90°.

摘要： Flowline components are assembled into high-pressure fluid transportation systems by a flange union. The flowline component comprises a body defining a substantially cylindrical central conduit. The conduit extends between first and second flat union faces and is adapted to conduct fluids through the body. The union faces are adapted to provide a mating surface for a flange union between the component and another flowline component. Accordingly, the union faces have a plurality of holes adapted to accommodate threaded connectors for forming the flange union. The holes are arranged in a defined array extending angularly around the conduit. Importantly, the array of holes on the first union face and the array of holes on the second union face are offset angularly relative to each other by an angle Δ. It will be appreciated that such components may allow changes in the direction of a flow line.

摘要： A densitometer assembly comprises a pipe fabricated from a high-yield steel, a radioactive source, and a detector. The radioactive source is mounted on an exterior wall of the pipe and is adapted to emit gamma radiation in a defined beam. The detector is mounted on an opposing, facing exterior wall of the pipe in alignment with the gamma radiation beam and is adapted to detect gamma radiation.

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.

摘要： Frac pumps have a fluid end and a fluid end block. The fluid end block has a plunger cylinder having a primary axis, a suction bore having a primary axis, a discharge bore, and a pump chamber. The pump chamber is defined by the intersection of the plunger cylinder, the suction bore, and the discharge bore. The fluid end block has a cylindrical portion extending along the primary axis of the suction bore. The cylindrical portion has a diameter greater than the diameter of the plunger cylinder. The pump chamber also has a ridge that extends radially inward from the walls of the pump chamber in a plane normal to the suction bore primary axis.

摘要： Dual path control fittings have a fitting body and a cylindrical plunger. The fitting body has a cylindrical bore, a first conduit, and a second conduit. The cylindrical bore provides a first inlet and an opening. The first conduit provides a second inlet. The second conduit provides an outlet. The cylindrical plunger is mounted for reciprocation in the bore and has a first conduit and a second conduit. The first conduit extends from one end of the plunger to a port on the circumference of the plunger. The second conduit extends transversely across the plunger. The plunger has a first position in which the port is aligned with the second fitting body conduit to provide a first path and a second position in which the plunger second conduit is aligned with the fitting body first and second conduits to provide a second path.
