METHOD FOR CREATING SYSTEM ADAPTED TO PROVIDE FILTRATION IN PRODUCTIVE RESERVOIR THROUGH PRODUCING WELL Russian patent published in 2005 - IPC

FIELD: oil production industry, particularly gas and/or oil producing wells, especially to increase hydrocarbon output from thick nonuniform productive reservoir through created filtering system.

SUBSTANCE: method involves cutting opening in casing pipe of the well within productive reservoir capping interval; additionally penetrating in separate productive reservoirs and/or beds and/or lenticels of the reservoir through previously cut opening and side channels; placing filtering material in the side channels and main well bore under pressure of natural vertical productive reservoir cracks opening and securing above cracks in opened state to activate fluid filtering of productive reservoir into producing well, wherein filtering material pressure in peripheral side channels spaced maximal distance from main well bore exceeds pressure of natural vertical productive reservoir cracks opening.

EFFECT: increased well yield and overhaul period, improved efficiency due to increased open area of the filtering system in proximal productive reservoir zone adjoining producing well and reduced costs and time for filtering system creation due multidirectional natural cracks utilization.
