METHOD OF OPERATION OF WELL Russian patent published in 2009 - IPC E21B43/00 

FIELD: oil and gas production.

SUBSTANCE: invention refers to oil industry and can be implemented at operation of oil wells. The essence of the invention is as follows: during operation of well a lift string with a filter and a shank end of alternate section by depth are lowered into a well; part of weight of the lift string is relieved by resting the shank end on a bottomhole of well; rock is de-compacted forming zones of dilation in a producing bed; the well is equipped with a deep well sucker-rod pump; then the well is put into operation; periodically above-plunger and sub-plunger parts of the pump are hydraulically connected; and a discharge line is partially or fully shut off from time to time. When a plunger of the pump goes up, periodic connecting of the above- and sub-plunger parts of the pump is repeated many times. Also amount of hydraulic connections per one run of the plunger up and length of plunger run are determined to ensure correspondence of repetition frequency of generated hydraulic pulses to frequency of lengthwise fluctuations of the lift string.

EFFECT: enhanced oil yield of deposit due to increased repetition frequency of pulses and increased efficiency of effect onto bed.
