FIELD: oil industry, particularly to produce oil with sucker-rod pump. ^ SUBSTANCE: method involves installing flow string with sucker-rod pump on rock in dib-hole through stepped pipe liner; arranging sucker-rod pump in well at maximal possible depth, wherein distance between sucker-rod pump and well head is equal to multiple pipe liner length. Sucker-rod pump is arranged so that the pump is in well oscillation antinode zone tuned for one of higher modes of natural system vibrations. Piston stroke is increased and decreased to maintain well output. Then sucker-rod pump is operated along with simultaneous applying dilatation and wave action on productive formations by sucker-rod pump movement. ^ EFFECT: increased well output and reduced water content in produced oil due to increased intensity of dilatation and wave action. ^ 1 ex |
