FIELD: oil and gas industry.
SUBSTANCE: production method includes descending of tubing string with bottom-hole pump and packer into the well, packer location above the interval of production formation, packer installation and oil extraction by bottom-hole pump. According to invention there used is a low flow rate well as a well, bottom-hole pump is equipped with bottom-hole pressure gauge and located not higher than production formation interval, at oil extraction in under-packer zone there maintained is the negative bottom-hole pressure.
EFFECT: increase of well productivity.
