Research on Perforation Performance and Reservoir Stimulation Effect of a New Self‐Cleaning and Aftereffect Perforation Technology

Geofluids, Volume 2026, Issue 1, 2026.
The development of low‐permeability reservoirs in the South China Sea X Oilfield is frequently hindered by severe compaction damage zones induced by conventional shaped charge perforation, which significantly impair well productivity. To mitigate these adverse effects, novel self‐cleaning and aftereffect perforation technologies have been proposed ...

Experimental Investigation of the Enhanced Damage Behavior of Nb17Zr33Ti17W33 HEA Reactive Projectile Impacting Fuel‐Filled Tank

Shock and Vibration, Volume 2026, Issue 1, 2026.
Nb17Zr33Ti17W33 high‐entropy alloy (HEA) is a novel energetic material developed by us, which exhibits non–self‐sustained chemical energy release under high dynamic loading conditions. To investigate the coupling influence between kinetic and chemical energy on damage behavior, we conducted a comparative study of the damage inflicted by Nb17Zr33Ti17W33

Resistive Heating and Thermal Decomposition of an Additively Manufacturable Electrically Conductive Explosive

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 1, January 2025.
Abstract The ability to transmit electrical signals through high explosive charges without using dense metal conductors could enable continuous monitoring of explosive charges with internally embedded sensors. With the sensor materials themselves being energetic, the impact on the intended detonation performance of the charge can be minimized. Embedded
