FIELD: oil-and gas industry.
SUBSTANCE: method includes descending a tubing string with a parker, equipped with an anchor, till the required installation interval, the anchor fixing with the parker installation between reservoirs, descending a pump and reservoir product extraction, simultaneous or separate. According to the method descend the parker with the anchor and additional rotation drive on a cable, which length is efficient enough the parker installation between reservoirs with the pump, located lower then a both reservoirs fluid level. After that fix the cable on the tubing string, equipped with the submersible pump with an additional cable of capacity efficient enough to extract both reservoir products. Descend the tubing string with cables into the borehole until parker dislocation between reservoirs. Install the parker with anchor between reservoirs supplying voltage via motor. Start up the pump supplying voltage with additional cable. Define upper reservoir capacity. Then supplying reverse voltage via cable to the drive, return the parker with anchor into bypass position. Then start up the pump supplying voltage with additional cable. In result define hydrodynamic properties of the lower level according to the first research. According to the research results select parkers with anchor mounting-dismounting period at the pump constantly working for the optimal production from the upper reservoir at the parker mounted till the fluid level decreases lower then the dynamic level of the less productive reservoir and higher then the top pump or from the both reservoirs at parker dismounted till dynamic fluid level is less then productive reservoirs one.
EFFECT: method efficiency increase.
