FIELD: oil extractive industry.
SUBSTANCE: method includes perforation of casing column in oil-saturated and water-saturated ranges of bed, lowering on tubing pipes of deep pump in such a way, that it was placed above productive layer and was connected to tail pipes column, lower end of which is lowered to pit face, and pumping away bed liquid. According to invention, speed of oil movement in hollow of casing column is increased oppositely to perforation in oil-saturated range of bed. This is realized due to decreased width of oil passing channel. For this at end of tail pipes column a device is placed - head piece in form of streamlined spindle-shaped body with thickened portion having length selected on basis of length of oil-saturated range.
EFFECT: higher oil yield.
