OIL/GAS PRODUCTION APPARATUS

摘要

An apparatus for boosting the pressure of flowing fluids includes a plurality of jet pumps (10a, 10b), each having a LP inlet for LP fluid, a HP inlet for HP liquid and a MP outlet for MP fluid. A fluid separator device (16) is connected to receive the MP fluid from the outlets of the jet pumps, 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) is connected to the liquid outlet of the fluid separator device and the HP inlets of the jet pumps (10a, 10b) for returning at least some of the separated liquid phase from the fluid separator device 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).

1. An oil/gas production apparatus for boosting the pressure of flowing fluids produced from oil and gas wells, the apparatus comprising:
a LP inlet line for receiving a LP fluid, a plurality of jet pumps, each jet pump including a LP inlet port connected to the LP inlet line to receive the LP fluid, a HP inlet port for receiving a HP liquid and a MP outlet port for MP multiphase fluid, a fluid separator device for separating the MP multiphase fluid in to a gas phase and a liquid phase, the fluid separator device comprising an inlet connected to receive the MP multiphase fluid from the MP outlet ports of the jet pumps, a gas outlet for the separated gas phase and a liquid outlet for the separated liquid phase, a liquid return line connected to the liquid outlet and to the HP inlet ports of the jet pumps for returning at least some of the separated liquid phase to the HP inlets of the jet pumps, a mechanical pump connected into the liquid return line for boosting the pressure of the separated liquid phase to a high pressure and delivering the resulting HP liquid to the HP inlets of the jet pumps, and a flow control system for controlling the flow of fluids through the respective jet pumps.
