FIELD: oil and gas production. ^ SUBSTANCE: wing with bridge is lowered into the well, also perforated connection pipe, lower casing string of design length equal to distance from bore-hole pump location to the specified interval in side bore, connection pipe with side hole and plug. The end of down-hole pipeline is passed through connection pipe side hole, fix it in piston that has inner channel and side hole and having outer diameter providing the gap 3-4 mm between piston and inner surface of lower casing string for process fluid flowing. In the course of connection there formed is an interconnection of internal space of down-hole pipeline and internal channel and side hole in piston. The fluid is pumped through the lower casing string under the influence of which the piston and down-hole pipeline together with it is moved till stop against wing bridge. Filter down-hole pump and upper casing string are attached to the plug. The layout is lowered into the well with arrangement of wing, perforated connection pipe and lower casing string in well side bore. During descending down-hole pipeline is fixed at outer surface of upper casing string. The oil is extracted by bore-hole pump through upper casing string, process fluid is pumped into specified interval of side bore through down-hole pipeline, piston inner channel, side hole of piston, gap between piston and walls of lower casing string and perforates connection pipe. ^ EFFECT: possibility to deliver equipment and supply process fluid into well side bore. ^ 1 ex, 2 dwg |
