Explosive Charges TRIZ Cases

See how a coaxial perforating charge uses a ring-shaped fracture explosive pack to eliminate co

See how optimized liner geometry with 100°-120° subtended angle creates constant-diameter jets,

A dual-geometry liner forms a rod-and-spade jet that penetrates deeply while creating larger, more consistent slotted holes.

A through-coating insert anchored in the explosive charge forms large-diameter tubular cores while reducing mandrel misalignment and axial bulk.

Simultaneous shaped-charge detonation creates extra circumferential dents in wellbore tubulars with fewer housings, less debris, and better sealing.

Localized tubular wall expansion forms protrusions that compress cement, collapse open channels, and reduce micro annulus leaks.

Controlled explosive expansion forms outward tubular protrusions that compress porous cement, collapse leak channels, and seal the annulus.

A two-layer foam mount prepositions the explosive charge, cuts setup time, and maintains stand-off for more reliable breaching.

A ball-and-socket stand lets EOD teams robotically align shaped charges vertically on uneven ground and lock the angle for stable boreholes.

Multi-pass extrusion with vibration aging and cryogenic treatment reduces stress variation in copper charge liners and improves penetration stability.

A two-layer foam mount speeds explosive charge placement while keeping stand-off distance consistent and shock transfer effective.

A foam carcass with composite liner and tamping strips enables on-site explosive filling, cutting effectively while reducing carried mass.

An overmolded cartridge confines and directs shaped-charge energy, improving downhole reliability, penetration, and reusable loading.

A containment cover and bulkhead let a fully assembled perforation tool travel safely, cutting well-site assembly time before deployment.

Different liner materials are combined to balance jet stretch, density, and momentum for more effective well perforation.

A focused fluid jet from a half-pipe shaped charge disables IED fuzing systems underwater while limiting container burst and shock initiation.

Combining life detection with a shaped charge cutter enables precise rescue blasting while reducing shock wave impact on nearby structures.

Constructive interference from multiple booster charges creates pressure hot spots on the liner, forming several SCJs for deeper, more uniform penetration.

Rounded housings and tapered fins help explosive downhole tools pass wellbore restrictions while reducing stuck-tool damage and debris.

Curved walls and multipoint explosive initiation shape stable high-velocity liquid jets while limiting cavitation and atomization during target disruption.

Precisely sized shaped charges and a high-strength steel housing create larger, consistent perforation tunnels for better fracturing in low-permeability rock.

A hollow booster uses a separate initiator and offset channel to detonate non-explosive booster material while easing transport and supply constraints.

Conventional shaped charge liners can leave residue in perforation tunnels; dissolvable materials and integrated tracers support clearer flowback monitoring.
