METHOD FOR INITIATION OF PERFORATORS RUN IN WITH TUBE STRING Russian patent published in 2013 - IPC E21B43/11 

FIELD: oil and gas industry.

SUBSTANCE: initiation method includes analysis of productive strata inhomogenuity, state of well case in the area of perforation impact, determination of intensity or potential impact of lower and/or upper stratum water in regard to the concerned productive stratum, arrangement of multiple shots in perforator. The method includes determination of potential remoteness or approach degree for charges along the perforator length, degree of charge power difference from each other along the perforator length and sequence of charge outburst and time of its outburst. The method includes design of perforator with at least one unit of uninterrupted power supply and memory for charge blowing in the perforator. Blowing of each multiple shot is envisaged with additional condition of physical events implementation in the well which are pre-programmed on condition of their exclusion as accidental events, the above program is written to the program in memory unit. Then at preset time the pre-programmed events in the well are implemented so that the blasting unit could outburst multiple shot.

EFFECT: increasing efficiency of perforation and well blasting operations.
