摘要
An apparatus and method for increasing the permeability of a productive oil formation, comprised of desensitized detonating cord with a plurality of steel sleeves thereabout, functioning as pressure compensators, disposed at pre-determined distances along the detonating cord to produce sequential pulse/delays upon ignition of the detonating cord. A high-pressure detonator ignites detonating cord. A protective shield, mounted about the detonator, reduces the explosive force, while preserving the kinetic energy effectuated by the detonator. An external plastic tube, arranged adjacent to the detonating cord, is filled with production enhancing chemicals, which are propelled through clogged perforations and stimulate the surrounding formation, thereby increasing transmissibility of a productive oil formation. A weight and Sample/Junk basket to retrieve materials after the process are mounted to the bottom of the apparatus. A 0.092 diameter support wire serves as the back-bone of the entire apparatus.
