MODULAR TIME DELAY FOR ACTUATING WELLBORE DEVICES AND METHODS FOR USING SAME |
摘要 |
An apparatus for controlling a wellbore energy train may include a firing head, a detonator cord associated with the firing head, and a plurality of serially aligned modules. Each module may include an enclosure, a first portion of a high order detonation material positioned at one end of the enclosure, a second portion of the high order detonation material positioned at the other end of the enclosure, and a low order detonation material interposed between the first portion and the second portion. A method for controlling an energy train generated in a wellbore may include serially aligning a plurality of the modules along the path of the energy train, and detonating at least one of the plurality of modules by detonating a detonator cord. |
