Abstract: The method can be used in the oil-producing industry for intensifying the production of oil and for increasing the intake capacity during the working of the bottom region of a seam and completion of wells. For producing pressure draw-down and repressuring cycles at the well bottom there is periodically changed the direction of flow of working liquid using controlled movement of jet pump. The value of maximal pressure draw-down is regulated, and periods of pressure draw-down and repressuring action are implemented with equal values of volumes of the inflow and the liquid pumpable into the seam in one cycle. These volumes in each subsequent cycle are increased. The cycles are continued until the increase in the values of the liquid volumes ceases. Chemical reagents are then pumped into the seam. If necessary, the cycles are repeated. The stimulation of the bottom region of the seam is completed with a pressure draw-down. 14 variants of formula.
