Water removing device for extremely high water content three-phase flow, and measurement device and method for extremely high water content three-phase flow

摘要

An extremely high water cut oil-gas-water three phase flow water removing device includes a mist eliminator (8), a fluid stabilizer (7), a liquid collection chamber (2), a fluid directing duct (5), an inlet connection pipe section (10), a gas outlet connection pipe section (9), a mixture liquid exit connection pipe section (4), a free water outlet connection pipe section (1). The function of the device is to effectively remove most of the free water from the high water cut oil-air-water three phase flow mixture liquid. An extremely high water cut oil-air-water three phase flow measurement apparatus and a measurement method using the water removing device are also disclosed.

1. A device for removing water from a high water cut oil-gas-water three phase flow, the device comprising:
an inlet connection pipe, a gas outlet connection pipe along a top portion of the device, a free water outlet connection pipe along a bottom portion of the device, a mixed oil-water liquid outlet connection pipe, for discharging any mixed oil-water liquid, and a fluid stabilizer mounted below the inlet connection pipe and above the mixed oil-water liquid outlet connection pipe, wherein said fluid stabilizer is configured to eliminate an unstable flow state of the mixed oil-water liquid and improve an effect of free water separation, wherein the device is configured such that a gas-liquid gravity separation process occurs when the high water cut oil-gas-water three phase flow enters device via the inlet connection pipe, and separated free water enters the bottom portion of the device and is discharged via the free water outlet connection pipe.
