A newly designed wellhead device has been developed in order to reduce filtration resistance and restore the reservoir-to-well connectivity for shock-wave impact on the bottomhole formation zone. The device can be used for enhanced recovery of crude oil by reservoir stimulation through the well while well completion and well repairs. In this paper, the problem of increasing the frequency of closing and opening the wellhead device is solved through a reliable design and a constant and continuous lower pressure compressed air supply, which allows it to be used to create pressure and rarefaction shock waves in the well. The use of the developed device allows to put into production low-permeability and isolated zones, improving connectivity and thereby facilitating filtration in the «reservoir-well» system, which boosts enhanced oil recovery and reduces oil cost.
