FLOW WITH CONTINUOUS OIL PHASE INTO FLOW WITH CONTINUOUS WATER PHASE INVERSION METHOD Russian patent published in 2019 - IPC E21B43/12 G05B13/02 

FIELD: oil and gas industry.

SUBSTANCE: present invention proposes the stream with continuous oil phase inversion method into the stream with continuous water phase and achieving one or more desired production parameters in the producing the oil and water containing fluid well, or stream with continuous oil phase inversion into the stream with continuous water phase and or more desired transportation parameters in the oil and water containing fluid transporting pipeline, wherein in the well or transport transporting a pump is located, at that, the method comprises the following steps: (a) reducing the pump rotation frequency until the inversion from the flow with continuous oil phase into the flow with continuous water phase is complete, or until the specified stopping condition is achieved; (b) if the inversion was not performed in step (a), regulating the pressure at the wellhead or the pressure on the transporting pipeline receiving side to perform the inversion; (c) stabilizing the flow under the condition achieved in steps (a) or (b); and (d) carefully adjusting one or both of the pressures at the wellhead and the pump speed to achieve one or more desired production parameters.

EFFECT: technical result consists in increase in the viscous oils production efficiency.
