FIELD: oil industry.
SUBSTANCE: the invention relates to the oil industry, and more particularly to a method for killing operating wells with subsurface pumping underground equipment when performing repair operations. The method includes pumping a killing fluid, closing the well for processing. At the wellhead, the following assembly is assembled from top to bottom: pump and compressor pipes-PCP, a packer, a lock support, a landing tool. The layout on the landing tool is lowered to a predetermined depth of the production string - PS of the well. Packer is seated in the PS of the well in a given interval. The packer-process tubing system PCP-PS is pressed. The tool seating from the layout is disconnected and the tool is lifted to the production tubing PCP. Next, a funnel is lowered into the EC of the well on the production tubing. Then the pump is lowered on the sucker-rod string through the production tubing with the funnel, the pump is connected to the lock support. The well is run into operation. Then, the well is killed by replacing the well fluid with circulation through the annular space of the well and the killing fluid PCP of the density determined by the given mathematical expression.
EFFECT: the technical result is an increase in the safety of operations in the repair of wells equipped with deep pumps.
