FIELD: engines and pumps.
SUBSTANCE: proposed method comprises reiteration of fluid evacuation from the well alternating with fluid accumulation of fluid therein at off borehole pump and adjustment of relationship between evacuation and accumulation duration depending upon well fluid dynamic level. In compliance with this invention, duration of all cycles is set equal to 40-80 minutes. Rated efficiency of borehole pump is set 3 to 5 times higher than the well producing ability. Duration of fluid evacuation at different cycles is periodically adjusted by changing of previous magnitude by 10-20% unless preset fluid level is reached.
EFFECT: high-efficiency, reliable operation.
