Ruitong's patented CFS perforating system is unique in its composite perforating charge, which includes a shaped charge and a case of high-energy propellants that coaxially assembles at front end of the shaped charge.
When detonating the perforating gun, the shaped charges conduct perforation. The propellants then follow the perforating jet into the perforating holes. The propellants travel, gather inside the hole, and deflagrate continuously under certain conditions of pressure and temperature, and then release sufficient energy directly to the formation. The streams of energy effectively break through the crushed zone and create multiple fractures and further penetration in perforation hole and the formation.
