FIELD: oil producing industry. SUBSTANCE: invention relates to jet plants used at repair-and-renewal and repair-and-isolating operations in wells. Said oil-well jet plant has packer and jet pump with active nozzle, mixing chamber and through channel with seat for sealing unit, all installed on tube string. Plant has radiator and receiver-converter of physical fields installed on logging cable passed through axial channel of sealing unit. Inlets of channels for delivery of handled medium and liquid working medium into active nozzle of pump communicate with inner space of tube string, respectively, lower then and upper than sealing unit. Plant has liner-stinger designed for threadless connection and disconnection with preliminarily installed in well drillable packer. Packer has through channel and check valve closing passage section of channel and opening towards productive formation. Packer has central channel and linear with guide funnel arranged below packer. Liner is installed for replacement by liner-stinger. Inner diameter of liner-stinger and inner diameter of liner with guide funnel is at least by 1 mm greater than diameter of radiator and receiver-converter. Sealing unit is installed for replacement by other functional inserts. Radiator and receiver converter is made for replacement by other bottom-hole devices. EFFECT: improved reliability of repair and isolating operations, enlarged operating capabilities of plant, optimization of operations carried out in well. 5 dwg
