SYSTEM FOR INDUCING WATER-GAS EFFECT ONTO BED Russian patent published in 2007 - IPC E21B43/20 

FIELD: oil industry, possible use for realization of water-gas effect while increasing oil yield of beds.

SUBSTANCE: system contains force pump, jet apparatus, booster pump, force wells, vessel with foam-forming surfactants, adjustable valves, line for feeding water into force pump, water forcing line, gas draining line, surfactant feeding line and water-gas mixture forcing line. In accordance to invention the latter contains separator of product of product wells onto oil, gas and water and gas forcing machine. Its intake is connected to output gas line of separator, and its discharge line - to receipt of jet apparatus. Gas forcing machine is made in form of liquid-gas separator and ejector, mounted with possible influx of gas from separator into its space and forcing by it of mixture of water and gas into liquid-gas separator, having closed contour for circulation of water and heating of this water, gas and mixture of water and gas.

EFFECT: increased efficiency and expansion of area of possible use of water-gas effect on formation due to increase of productiveness in gas and efficiency with increase of pressure at intake of jet apparatus.
