FIELD: oil and gas industry.
SUBSTANCE: installation comprises underground equipment assembly run in the well using the pipes string, including funnel-positioner, lower packer, reducer-positioner, device of injection distribution, top packer, extension. Device of injection distribution contains casing and removable parts, is equipped with to independent pressure gauge, middle independent pressure gauge, and bottom independent pressure gauge. Top and bottom unions are installed in the removable part of the device of injection distribution with possibility of both unions removal by one round run operation.
EFFECT: assurance of possibility of information acquisition on injection pressure upstream and downstream each union for long time period, reception of reliable data on injection mode, increased process reliability.
