CONTROL METHOD OF REMOVAL OF LIQUID AND GASEOUS PHASES FROM WELL FLUID SEPARATOR RESERVOIR Russian patent published in 2015 - IPC E21B43/34 E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: removal of liquid and gaseous phases from a well fluid separator reservoir is controlled via two separate measuring channels, with provision of flow measurements of quantitative parameters as to liquid and gas, with further combination of these flows into one flow for further conveying. A flow regulator installed in a gas line maintains within the specified limits the excess pressure in the separator reservoir over pressure in a phase mixing chamber based on the data on change of pressure difference of media contained in the separator reservoir and in the phase mixing chamber while level of liquid in the separator reservoir is maintained by the flow regulator in the liquid line based on the data on changes in level of liquid in the separator reservoir.

EFFECT: providing effective maintenance of boundary level of media in the separator reservoir at simultaneous maintenance within the specified limits of excess pressure in the separator reservoir over pressure in the liquid and gas mixing chamber.
