Methods of controlling the dynamic pressure created during the detonation of a shaped charge using a substance

摘要

Summary the methods to control the dynamic pressure created during the detonation of a shaped charge using a substance, a method of controlling a dynamic pressure created during the detonation of a shaped charge comprises: positioning the shaped charge in a hole of the well in which the load Mo Ldada comprises a main charge of explosive.Where a substance is included in the main charge of explosive or is positioned adjacent to main charge of explosive.In which the substance increases or decreases the dynamic pressure or increases or decreases the duration of a pulse of pressure created during the detonation of the shaped charge; while a load is shaped substantially identical without the substance does not increase or decrease the dynamic pressure or increase Or decreases the duration of the pulse pressure during detonation.A method of controlling the balance of a portion of a hole of shaft comprises positioning the shaped charge in the portion of the hole of shaft; and creating a desired balance in the portion of the bore of the well.
