EFFECT HIGH EXPLOSIVE TYPE ON THE PERFORMANCE OF SHAPED CHARGE USED IN OIL INDUSTRY

Abstract

Several explosives have been tested numerically to study their effect and performance of the produced jet characteristics and predicted jet penetration into concrete target material. TNT, cyclotol, RDX, HMX, PETN and LX-17 have been used in this research as a shaped charge oil well perforator, where the Autodyn hydrocode has been implemented with the jetting analysis solver and jet penetration to estimate both the jetting output data and the relevant penetration depth for these studied explosives. Results show that HMX explosive exhibiting the highest detonation velocity, has the largest penetration depth into Concrete 26MPa target. The relative jet tip velocity to the Gurney characteristic velocity of an explosive has been found to be around 2.5 for the used explosive charges, whereas the scaled jet tip velocity to the detonation velocity of an explosive has been found to be one for the studied six explosives.
