Key words: cumulative perforation, support of well, stone, shaped charge, rock, crack, X-ray tomography, perforation, well.
Describes the new design of the cumulative perforating. The results of laboratory experiments comparative validity of the new and staff perforating gun systems. Formation a network cracks between perforations using a new gun, increases the drainage characteristics of the producing formation into the perforation interval.
The paper describes the results of benchmark tests of effects of conventional «Sparka» cumulative perforation system developed by VNIPIvzryvgeofizika institute on well casing models and a carbonate formation (cementsand) model.
The method of X-ray computed tomography used to investigate the changes in the internal structure of samples.
Experimentally, at high pressure, shown the advantage of the use perforators with paired charges than regular perforating.
