PROCEDURE FOR COMPLETION AND OPERATION OF WELL Russian patent published in 2010 - IPC E21B43/00 

FIELD: oil and gas production.

SUBSTANCE: there is installed packer with by-pass facility underneath. Further, a deep-well pump is lowered on a flow string and well fluid is lifted via the flow string when the pump is alternately turned on and off. The by-pass facility is installed between the packer and the deep-well pump; the facility operates in "open" or "close" positions. When the by-pass facility is in the "close" position, the well is completed with the deep-well pump to a complete or partial replacement of water or sealing fluid under the packer. The deep-well pump is turned off; the by-pass facility is set from the position "close" to the "open" position; annular gas with reservoir fluid is bypassed through the facility via the flow string from under the packer space into cavity of the flow string; the well is put into flowing well operation.

EFFECT: raised efficiency of procedure for intensification of completion and operation of well with high gas factor, increased period of well flowing operation.
