A METHOD AND APPARATUS FOR SUBTERRANEAN FRACTURING

摘要

A subterranean formation stimulation system, comprising a gas generator (46), a high pressure seal (50,53), and means (44) to activate the generator. The high pressure may be a packer and or plug having an outer sealing surface on its outer periphery. The outer sealing surface is configured for metal to metal contact with the inner circumference of wellbore casing. The gas generator can be compressed gas or a propellant. The means to activate the generator includes a shaped charge. The system is disposable in a wellbore (5) on wireline (34), slick line, or tubing.
