METHOD FOR DEVELOPMENT OF PRODUCTIVE FORMATION OF WELL WITH CUMULATIVE CHARGES AND DEVICE FOR IMPLEMENTATION THEREOF (EMBODIMENTS) Russian patent published in 2020 - IPC E21B43/117 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: group of inventions refers to shooting and blasting operations in oil and gas wells. Method for development of productive stratum of the well by cumulative charges includes delivery to perforation interval of productive formation of bearing structure with installed along it cumulative charges, subsequent actuation of cumulative charges with formation in productive formation of well mine working with dimensions sufficient for movement along it of load-carrying structure or its part with cumulative charges with movement of bearing structure or its part with cumulative charges on mine working into the depth of formation. To perform bending of bearing structure in direction of formation and giving required direction to mine working, bearing structure with cumulative charges is placed in guide device, which before turning down or before shooting charges is turned in required direction, wherein to obtain a given shape and size of the mine working, said cumulative charges before the shooting are oriented relative to the mine working.

EFFECT: high-quality hydrodynamic connection of the well with the formation.
