METHOD OF PUMPING GASSY FLUID INTO BED Russian patent published in 2009 - IPC E21B43/20 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas industry, particularly to methods of pumping gassy fluid into bed. The method of pumping gassy fluid into bed consists in mixing gas with fluid, in transporting gassy fluid via an independent channel and in pumping this fluid into a bed. Mixing gas with fluid is performed in an ejector with opposite swirled equal flows of fluid, while transporting it through an independent channel is carried out at a rate facilitating laminar flow of gassy fluid. The disclosed method reduces pressure values at pumping gassy fluid because gas does not escape from fluid, which is provided by laminar flow of gassy fluid. In addition, gas plugs are not formed during gassy fluid pumping into bed, owing to elimination of intensive gas release from fluid.

EFFECT: reduced pressure at gassy fluid pumping, eliminating formation of gas plugs during pumping gassy fluid into bed.
