METHOD TO EXTRACT OIL OR GAS FROM MULTIPAY WELL AND DEVICE TO THIS END Russian patent published in 2010 - IPC E21B43/14 E21B43/12 

FIELD: oil-and-gas industry.

SUBSTANCE: method comprises measures to decrease bed cross flows. Dynamic flows of oil or gas from every production bed or production beds with higher bed pressure are divided into sections and crossed. To this end, anchor is arranged above production bed or production beds for tube with radial orifices to be suspended to said anchor opposite said beds and for smaller-diametre tube to be inserted therein. Proposed device comprises elements intended for decreasing bed cross flows and anchor mounted above production be or beds. Elements intended for decreasing bed cross flows represent tube with radial orifices, smaller diametre tube inserted therein and stem with channels fitted at pipes top edges. Said tube are suspended to anchor stem.

EFFECT: increased production due to reduced bed cross flows.
