IMPROVEMENT DURING TRANSPORTATION OF FLUIDS FROM WELLS Russian patent published in 2019 - IPC E21B36/00 F17D1/14 

FIELD: technological processes.

SUBSTANCE: group of inventions relates to production of fluid media from underground reservoirs and, in particular, to methods for transportation of produced fluid medium from the well and associated equipment. Method includes operation of at least one pump for pumping fluid medium through at least one section of pipeline and generation of frictional heat at said section. Frictional heat is equal to or greater than the predicted heat losses in order to protect against one or more of: formation of hydrates; occurrence of paraffin; and paraffin deposition. At that, produced fluid medium represents multiphase fluid medium from well. At that, said pump used for pumping of produced fluid medium includes the first, multiphase pump. Said method comprises operation of multiphase pump to increase fluid medium pressure to produce single-phase produced fluid medium downstream of pump.

EFFECT: technical result is ensuring uninterrupted flow in underwater pipelines, which can be used for transportation of hydrocarbon fluids over long distances.
