FIELD: oil and gas industry. SUBSTANCE: according to method, opening of productive beds is performed as follows. Opening is cut out in production string above roof of productive bed, and through this opening, drilling is effected of radially directed inclined holes of small diameter. Drilling is performed beyond zone of sedimentation and beyond-string fluid flows. Subjected to drilling are all interlayers of productive reservoir. Used in this operation are composite solutions on oil base. Composition of solutions is chosen on basis of core analysis with core taken from nearest well within given area. During normal operation, opening in production string is closed with slot-type filter. EFFECT: high efficiency.
