FIELD: oil and gas industry. ^ SUBSTANCE: method consists in lowering assembly containing flow string equipped with at least one packer for uncoupling objects with disconnector- connector or without packer, electro-driven pump without or with case furnished with inlet module, power cable, submersible electric motor with or without block of submersible telemetry, shank end and at least one controlled electric valve with gate. Valve opening regulates fluid flow at least from one object passing through the valve to the above positioned inlet module of electric driven pump. According to the invention the electric valve of electro-magnetic or electro-mechanical operation is electrically connected either with immersed electric motor or with the block of immersed telemetry or with the cable. Additionally, it is connected mechanically rigidly or not rigidly either with immersed electric motor, or with the block of submersible telemetry, or with the case, or with the shank end. Also electric valve is positioned above the packer. Notably, the electric valve is made either with one inlet hydraulically connected with space under the packer or above the packer, or with two isolated inlets, one of which is hydraulically tied with space under the packer, while another is tied with space above the packer; or the assembly can be equipped with two electric valves, one of which is hydraulically connected with space under the packer, while another is connected with space above the packer thus facilitating both controlled shutting off and passing flow of fluid through it for an upper or lower object, or simultaneously for lower and upper objects without or with measurement of flow parametres. There are versions of facility for implementation of this method. ^ EFFECT: increased efficiency of process for extracting reservoir fluid ensuring stock taking and regulation of yield of each operated object. ^ 32 cl, 30 dwg |
