摘要： A commingling device for combining fluid flows includes an outer fluid line for a first fluid having an inlet end and an outlet end, and an inner fluid line for a second fluid having an inlet end and an outlet end. The inner fluid line has an outlet nozzle at said outlet end, the nozzle being mounted substantially axially within the outer fluid line and configured to direct said second fluid towards the outlet end of the outer fluid line. As a result, the first and second fluids flowing through the inner and outer fluid lines are combined and flow together towards the outlet end of the outer fluid line.

摘要： A slug mitigation system for subsea pipelines includes a riser located between a low level and an upper (above sea-) level of a pipeline, where an inline separator, e.g. an “I-SEP”, is located upstream of a first stage separator. A throttling valve or fixed restriction is located downstream or upstream in series with the inline separator. Further aspects may also include a surface jet pump upstream of the in-line separator and/or a cyclonic separator downstream of the in-line separator.

摘要： An apparatus for boosting the pressure of flowing fluids includes jet pumps (10a, 10b), each having a low pressure (LP) inlet for LP fluid, a high pressure (HP) inlet for HP liquid and a medium pressure (MP) outlet for MP fluid. A fluid separator device (16) receives the MP fluid from the outlets of the jet pumps, and includes a gas outlet line (20) for a separated gas phase and a liquid outlet (22a, 22b) for separated liquid phase. A liquid return line (24b, 38) returns at least some of the separated liquid phase to the HP inlets of the jet pumps, and a mechanical pump (32) is connected into the liquid return line for boosting the pressure of the liquid delivered to the HP inlets of the jet pumps. A flow control system (6) is provided for controlling the flow of fluids through the respective jet pumps (10a, 10b).

摘要： A jet pump comprises a HP inlet vent, a nozzle connected to the HP inlet vent via a HP fluid conduit and configured to discharge a first fluid flowing through the HP inlet into a nozzle discharge zone, a LP inlet vent, a LP fluid conduit connected to the LP inlet vent and configured to discharge a second fluid flowing through the LP inlet vent into the nozzle discharge zone. A mixing tube is provided downstream of the nozzle discharge zone for mixing the first and second fluids and an outlet vent is located downstream of the mixing tube for discharging a mixture of the first and second fluids from the jet pump. The jet pump includes a spinner mechanism upstream of the nozzle discharge zone for causing spinning rotation of at least one of the first and second fluids about a longitudinal axis of the nozzle. In one embodiment the spinner mechanism includes a LP inlet chamber connected to receive the second fluid from the LP fluid conduit, the LP inlet chamber comprising a fluid passageway that extends circumferentially around the nozzle to cause rotation of the second fluid around the longitudinal axis of the nozzle.

摘要： A system and method for boosting the pressure of multi-phase fluids to enable handling of slug flow from oil and gas wells. The system is arranged to include a cyclonic separator having outlets of a first gas-rich line and a first liquid-rich line, a gravitational separator having outlets of a second gas-rich line and a second liquid-rich line, downstream of the cyclonic separator. There is also a gas compressor for boosting pressure in the second gas-rich line and a liquid pump for boosting pressure in the second liquid-rich line. The boosted gas and liquid is received by a commingler downstream which outputs a combined fluid flow. Control valves are provided at various stages of the system that are activated in response to slug flow detected by flow regime detectors upstream of the cyclonic separator. The system is, overall, able to be much smaller than a convention slug catcher system and, in fact, the gravitational separator may be comprised of a pipe section the same or similar to the inlet from the well.
