FIELD: oil and gas industry.
SUBSTANCE: method involves well drilling, arrangement of downhole pumping equipment in the well at the chosen depth, pump operation in a periodic mode with pump stops for oil accumulation in the well, and reduction of counter pressure on a formation during oil accumulation. According to the invention, preferably two horizontal side shafts performing the function of oil accumulators are drilled above upper perforation holes. Pumping equipment is arranged on the face of the well. Periodic pump operating mode is performed so that upper dynamic level is higher than static level, and lower dynamic level is maximum approximated to the pump suction level so that its delivery coefficient is not lower than 0.2.
EFFECT: improving efficiency, versatility and processibility of the method owing to increasing the oil production.
