FIELD: geology.
SUBSTANCE: invention relates to means for producing geological space for tests in downhole conditions of new equipment for use in wells. Said system comprises at least one unproven downhole device comprising at least one drilling device with hydrodynamic bearing or downhole piston device. Said unproven downhole device includes an opening element for opening well without drilling unit configured to be actuated by at least by hydraulic means. Opening element for opening well without use of drilling unit is further configured for actuation by an explosion, a cable or a combination thereof, and configured for deployment through upper end of exhausted wells within one or more pipelines so that opening element opens inner opening in axial direction along and radially in wall. Debris, formed when opening inner opening, is placed and compressed in lower end of exhausted well for arrangement of hardening sealing material, hardening sealing material is placed in axial direction over debris and in wall at lower end of exhausted well for creation of similar geological structure over hardening sealing material, comparable with at least one part of geologic structure of well. Geological test space is configured for used for empirical measurement of operating parameters of at least one unproven downhole device. Proposed invention provides for cheaper methods for comparative analysis, development, testing and improvement of access to annular space and for selective placement of loaded pipelines and borehole barrier elements at necessary underground depths between annular space when accessing, maintaining and/or closing of parts of well to isolated parts by erosion and corrosion. This in turn prolongs service life of well until complete depletion of reservoir and also reduces risk associated with arrangement of borehole barrier elements and responsibility for environmental pollution from improperly liquidated well.
EFFECT: disclosed is a system for providing space for formation of geological test space for checking unproven devices with exhausted geological structure during closure of well.
