发明名称 FLOW RESTRICTION CONTROL SYSTEM FOR USE IN SUBSURFACE WELL
摘要 FIELD: oil and gas industry.SUBSTANCE: group of inventions is related to mining engineering and may be used for regulation of fluid inflow to the well. The system contains a flowing chamber through which a multicomponent fluid passes, at that this chamber contains at least one input, one output and at least one structure spirally located in regard to the output and thus facilitating helical swirling of the multicomponent fluid flow around the output. According to another version the system contains a flowing chamber with the output, at least one structure facilitating helical swirling of the multicomponent fluid flow around the output and at least one structure preventing redirection of the multicomponent fluid flow to radial trajectory passing towards the output.EFFECT: prevention of gas cone and/or water cone formation around the well.24 cl, 5 dwg
